How to open your own business so that it makes a profit and does not require significant financial investments?
Choose current idea and niche market for entrepreneurial activity where the competition is the least fierce and the clientele is extensive.
You can engage in the provision of services in various areas of the national economy or trade commerce.
A profitable aluminum can business is an interesting solution for starting your own business.
Different ways to start
For packaging alcohol and soft drinks manufacturers use several options - glass, plastic and aluminum cans.
After consuming the contents, there is a lot of container for disposal. You can build a profitable business on this.
Possible destinations:
- Open a collection point for aluminum cans with subsequent transportation of the collected material to large industrial enterprises for processing.
- To make a profit on the remelting of aluminum cans - to hand over recyclable materials for further processing.
- Open manufacturing facility for the production of new aluminum cans for companies that produce alcoholic and non-alcoholic products.
Each option is profitable, but with different investments.
If the start-up capital is small, the best idea is to open a collection point for aluminum containers.
This will allow you to earn funds for further business development.
How to take the container
The beginning of any entrepreneurial activity - registration of IP ( individual entrepreneur) and the choice of taxation system.
For this you need:
- Pay the mandatory state fee of 800 rubles.
- Submit documents to the tax office.
- To make it convenient to work in the future (it may be necessary to conclude agreements with other market participants), it is recommended to print.
- Open a bank account.
In order to save your own time, it is better to use the services of a professional lawyer.
On average, documenting an IP will cost from 4,000 to 5,000 rubles (a lawyer, a current account, a seal) plus a state duty (800 rubles). The total cost is up to six thousand.
It is advisable to choose a simplified taxation system.
The next step is renting a room.
The collection of aluminum containers can be organized in any area, a small basement with good heating and lighting is enough.
The cost of renting a suitable area starts from three thousand rubles, but if you set up a business in major city or the capital, you will have to pay a large amount.
It is necessary to hire at least one employee who will deal with the acceptance of aluminum cans.
His wage per month - 8000-12000 rubles.
In addition, you need to pay money to people who donate containers - 20-30 kopecks per can, and pay utilities- about 1000 rubles. per month.
The total investment to open a business on aluminum cans will be at least 18,000-20,000 rubles.
If the premises are located in passing place, then in a month you can collect about three tons of recyclables.
Its implementation to a large industrial enterprise will bring:
3 tons * 30,000 rubles = 90,000 rubles.
Excluding mandatory expenses net profit can amount to 70,000 rubles minus the rental of vehicles for the removal of the resulting scrap, which proves the excellent profitability of the business.
Recycling
The collected aluminum scrap can be melted down into briquettes for further shipment to processing plants.

Possible recycling methods:
- Cutting scrap with a shredder, cleaning from household waste, washing, drying and pressing. The cost of a Chinese-made crusher is from 380,000 rubles, and the price of a new press, depending on the series, is 75,000-45,000 rubles plus an electromagnet for cleaning.
- Multi-stage grinding of aluminum scrap with the removal of impurities. The result of processing is powder or fine metal flakes. The organization of such production requires complex expensive equipment, large areas and lines of industrial processing.
- Pyrolysis processing of recyclable materials with preliminary crushing, cleaning and washing. The production scheme is also multi-stage, but a pyrolysis plant must be added to the equipment complex, costing about 2-3 million rubles.
Without a decent start-up capital, you should first earn free funds for the acquisition necessary equipment, which will allow you to get a lot of money on the remelting.
Own production
When injecting solid investments into the business on aluminum cans - from seventy to eighty million rubles - you can earn on receiving 800 million containers per year.
What will require large investments:
- Finding and renting a spacious room.
- Heating and lighting of the production hall.
- Registering a business as an LLC.
- Food aluminum in rolls.
- Press for bending material.
- Body molding machine.
- Washing and drying machines.
- Paints and varnishes.
- Rotary apparatus.
- Neck molding machine.
- Container inspection chamber.
- Press for scrap processing.
In addition to the cost of purchasing equipment for a complete production line, it is necessary to pay for the work of a large number of maintenance personnel.
All expenses are paid off by the cost of products produced annually.
The downside is the large start-up capital.
Business on aluminum cans is a profitable business that brings income that exceeds financial investments by 2-3 times.
Therefore, it makes sense to consider the idea as quite suitable for starting your own business.

Aluminum cans appeared on the shelves about fifty years ago.
Since then they have become one of the the most popular tare for storage:
- lemonades;
- sodas;
- low alcohol drinks.
There is not a single grocery store that would not offer its customers a can of cold drink on a hot summer day.
The popularity of aluminum modern marketing quite clear. This metal has good stability to organic acids contained in carbonated drinks and fermentation products. Add to this the light weight, and you have the perfect metal for making cans for soft drinks.
When aluminum cans came into use, a serious problem arose street clogging and even whole cities. After all, many people do not think about the surrounding cleanliness at all and throw the cans right on the ground. However, to date, this issue has been completely resolved. Banks can be handed over to collection points and, what is most remarkable, receive for that money.
Read about it below:
- how to choose the right banks for sending for processing;
- how much are aluminum cans accepted;
- how to earn more.
Aluminum cans compare favorably with other types of containers in the following ways: benefits:
- save the initial qualities of the drink are better than plastic containers;
- fully protect content from influence environment, and the metal itself does not have a negative effect on it;
- aluminum cans are beneficial to manufacturers due to easy transportation(they are light enough and do not fight);
- banks are especially good for buyers because cool quickly and are able to "hold" the cold for a long time;
- it is a reusable product and it may be subject to further recycling.
Such enterprises are resellers and offer enough favorable prices upon delivery of non-ferrous metal scrap at retail, that is, by kilograms. The cost per kilogram in some points may increase due to the number of cans handed over. Before delivery, inquire about the availability of the reception point for the implementation of this activity.
Many of the organizations offer not only the removal of scrap, but also the following services:
- cleaning;
- sorting;
- metal pressing.
True, the price of this varies.
If it is possible to sell banks in bulk from several thousand kg, it is better to cooperate directly with metal base or processing plant.
They can also organize self-delivery of the product, and the price will please.
The only difference will be that the banks will have to on one's own:
- cleanse;
- sort.
Recently, in Russia, the third option for the "realization" of aluminum cans has become more and more famous.
This is a special machine for receiving aluminum cans ( vending machine), which carries out the reception by the piece. In big cities, such miracle machines are usually shopping malls. The average cost of receiving one aluminum can in such a machine is about ten kopecks apiece, and any enthusiast of any age can return it.
Though this system just starting to develop in our country, it is safe to say that it is the future of scrap metal collection.
Admission conditions
A huge plus for the delivery of aluminum cans is that the seller receives the money immediately after the delivery of the container. However, it is worth noting that in each type of enterprises and private companies terms recycling may vary.
Not all collection points accept aluminum cans by the piece.
The minimum weight is usually one kilogram, and in large enterprises and processing plants - one ton.
If you want to hand over banks piece by piece, then it is better to contact resellers.
They can find through:
- janitors;
- sellers in the store.
But their prices are right too. You can’t hope to rent a bank for a lot.
It is more profitable to hand over one aluminum can to a special machine for receiving them, but keep in mind that they are still only in large cities.
They only accept banks that meet the following criteria:
- clean;
- whole;
- with intact barcode.
It is easier and more profitable to donate kilograms.
Private reception points take banks of any:
- type;
- forms;
- quality;
- destination.
Even crumpled dirty beer cans stained with earth.
Such companies carry out:
- cleaning;
- sorting;
- remelting
If you would like to receive more money per kilogram, it is better to hand over banks:
- clean;
- sorted.
Each organization determines the sorting conditions itself.
Most often, they ask distribute container according to:
- volume;
- appointment.
Less often - by chemical composition.
Also, if possible, they are asked to place cans in pressed bales for optimal loading into vehicles ( upon order pickup).
As for processing plants, they usually buy already pressed an aluminum can from several hundred kilograms.
Reception is carried out according to regulatory documents regional scale, and the seller must have an identity document with him upon delivery.
Scrap is accepted only:
- in pure;
- sorted by varieties and groups.
To the composition of non-ferrous metal scrap on large enterprises there are certain important requirements:
- the metallurgical yield must be at least 90%;
- paper, iron and dirt are not allowed;
- it is required that the mass of the metal be 95% aluminum, other metals are allowed, but they must be the smallest fraction;
- radiation pollution is unacceptable.
Prices for aluminum cans at collection points
To form average prices, consider the cost of receiving aluminum cans at three types of enterprises:
- those that accept banks with a total weight of several tens and hundreds of kilograms;
- enterprises buying scrap from a kilogram;
- places where you can rent cans by the piece.
From 10-100 kg
At this point, we took four large enterprises that either themselves are engaged in the processing of scrap metal, or directly cooperate with such plants.
Mostorma
This enterprise is engaged in the reception of raw materials of various types. One of them is aluminum cans. The company's website states that they accept weight not less than 0.5 tons. The minimum price is 45 rub./kg.
The price increase depends on three parameters:
- weight characteristics(the more you rent, the more the cost of raw materials per kg becomes);
- raw material purity(lack of dirt and impurities);
- possibility self delivery goods.
The company also notes that the reception of cans is possible only compressed.
SecondResource
One of the largest enterprises of the cultural capital of Russia offers the purchase of aluminum cans from 50 kg by price from 65 to 75 rubles per kg when using your own transport.
The price varies depending on the purity of the offered raw materials.
Its cost will be lowered by 5% if the scrap contains:
- dirt;
- impurities.
If the seller cannot deliver the goods on one's own, the price of aluminum cans will vary from 40 to 68 rubles per kilogram.
MDM VtorMetal
Moscow enterprise accepting aluminum cans at a price 64 rubles/kg.
For this price, you can only sell scrap metal that meets the following criteria:
- clean;
- compressed;
- free of foreign metals and dirt.
Also company offers a surcharge 10% when accepting payment by bank transfer.
Ecopolis
Here, for a kilogram of scrap aluminum cans, you can get from 20 rubles. The company emphasizes that the price will rise depending on the amount of scrap delivered. However, the company's website does not provide accurate information about the price increase.
From kilogram
Here are the five most popular private reception points of the three largest cities in Russia.
MetalExpert24
The Moscow company offers the purchase of aluminum cans at a price 68 rubles/kg. Terms of price increase or decrease not specified, but proposed calculation cost goods according to the photo.
Metal+
Moscow-based Metal+ lists two prices per kilogram for aluminum cans. 45 rubles per kilogram will be received by those who rent cans at retail, that is from 1 to 99 kg. And those who decide to sell over 0.1 tons receive at a time 50 rubles for one kilogram. At the same time, in the cost export is included raw materials enterprise.
Mosvtormetall
Here the price is 64 rubles/kg, but does not include pickup. Also, the company's website notifies that the price of large quantities of goods may increase markedly.
OOO Resurs
On the this enterprise the price is indicated from 40 rubles per kg of aluminum cans. The cost can rise to 42 rubles for cashless payments and up to 45 rubles for the delivery of scrap from one ton.
Riten Metal
The Novosibirsk enterprise "Riten Metal" is ready to buy scrap aluminum cans for 59 rub/kg. Here, accepting payment by card is also beneficial: the cost will increase to 60 rubles per kg.
The company only accepts the following banks:
- clean;
- sorted.
The price may increase depending on the weight of the item.
By the piece
Neither large enterprises, nor small collection points will not accept aluminum cans weighing up to one kilogram.
Piece by piece, banks can only be handed over to resellers or found in your city vending machine- machine for receiving aluminum cans.
At piece by piece acceptance of aluminum cans, the price per piece varies, but on average they are from 30 to 50 kopecks.
The average price of aluminum can scrap is presented in the table:

To get as much profit as possible from the delivery of aluminum cans, you need to prepare a favorable ecological environment
Aluminum casting at home is quite affordable, the main thing is to follow the technology and know some important nuances. Of course, this is not a banal lead casting, which many have tried to do using battery scrap.
The melting point of aluminum is twice as high and reaches an average of 660 degrees Celsius, it all depends on how pure the metal used was, so aluminum cannot be fully melted on a fire.
How to bring aluminum to a temperature when it starts to melt? This can be done in different ways, for example using coal or coke, but in this case it is necessary to supply air with bellows, thus increasing the temperature of the flame.
You can use natural gas burners installed in a homemade furnace, a muffle furnace or acetylene torches - the choice is yours.
The technological process of aluminum casting is as follows:
- the raw materials are washed, various impurities are removed, and then they are crushed to the desired "fraction" and melted (they take care of the removal of combustion products from the working area, using, for example, a fan);
- when the metal becomes fluid, the slag is removed and aluminum is poured into prepared molds. They can be unnecessary steel containers or special forms made of alabaster or gypsum, in the latter case they are broken after the poured metal has cooled. The future part itself is made of foam or paraffin, which is then covered with plaster. Molten aluminum burns out the "blank", repeating its volume.
The best material for the base of the workplace is steel sheet, it will help protect against accidental spillage of molten aluminum or splashes.
For casting small products, so to speak, in a "piece" way (weight of raw materials - no more than 0.15 kg.), You can try the following technology:
- take a small empty jar of tin, put pieces of prepared aluminum into it;
- this jar is inserted into a larger jar (on stands) so that a kind of thermos is obtained - the surfaces of the jars should not touch, the gap should be up to 1 centimeter;
- in the bottom of the larger jar, an inlet (several centimeters in diameter) is formed to supply the flame of the burner. The top of the jar is covered with a ceramic lid with adjustable holes for the removal of combustible gas;
- position the burner so that the flame goes inside the large can and melts the scrap in the small can. Cans can be used in this way only for one heat.
For multiple use, you need to make a crucible with a chute for pouring molten aluminum.
Typical mistakes:
- insufficient heating of the metal mold, aluminum can solidify unevenly and non-uniformly, since it cools faster at the "cold" surface of the mold;
- a lot of moisture in plaster and foam molds. When evaporating, it forms cavities and shells, so the workpiece is thoroughly dried;
- slow pouring of metal into molds, when it simply does not completely fill the mold, so aluminum needs to be heated more strongly, and poured into molds faster;
- cooling the casting with water. Yes, I want to admire the fruits of my efforts as soon as possible, but in this way, invisible cracks form in the metal, which, when processed, can lead to its destruction.
For many, the term Foundry» is closely related to overwork and special professional skills and abilities. Actually cast the part out required metal real for the most ordinary person without vocational training at home. The process has its own subtleties, but it is within the power to do it at home with your own hands. Outwardly, it resembles the manufacture of lead weights for fishing. Features of the aluminum casting process are associated with technical specifications material.
How to piss aaluminum
characteristics of aluminum. Aluminum is one of the most common metals.
It is silvery-white in color, lends itself well enough to casting and machining. Due to its characteristics, aluminum is equipped with high thermal and electrical conductivity, and also has corrosion resistance.
For technical aluminum, the melting point is 658 degrees, for high purity aluminum - 660, the boiling point of aluminum is 2500 degrees.
For casting aluminum, home heating appliances are unlikely to be useful and provide the desired temperature. It is necessary to melt aluminum by heating it to a temperature of over 660 degrees.
Aluminum casting: the choice of heat source
As a heat source for melting aluminum, you can use:
- A very effective method is achieved thanks to a self-made crucible muffle furnace. A crucible is installed in the working surface of this furnace ( essential tool for melting aluminum), raw materials are added to it. With the help of a muffle furnace, it is very easy to cast aluminum.
- To obtain the melting temperature of aluminum, the combustion temperature of liquefied or natural gas is sufficient, in which case the process can be performed in a home-made furnace.
- With a small amount of melting, you can use the heat obtained by burning gas in a household gas stove.
- The required temperature will be provided by gas cutters or acetylene generators, if any in the household.
Aluminum preparation
Despite the fact that the melting process will be carried out at home, it must be taken responsibly. The metal must first be cleaned of dirt, crushed into small pieces. In this case, the melting process will go faster.
The choice is stopped on softer aluminum, as a purer material, with fewer impurities. During melting with liquid surface metal slag is removed.
Sand casting
Several technologies are used for the manufacture of casting parts. The simplest is sand casting:
- If it is required to produce an aluminum part of a simple shape, then casting can be performed open way directly into the soil - silica. They make a small model from any material: wood, polystyrene. Installed in a flask. The soil is laid around in small layers and carefully rammed. After the sample is removed, the silica holds its shape well and casting is done directly into it.
- As a forming mixture, you can use sand combined with silicate glue, or cement mixed with brake fluid. The ratio of materials should be such that if the mixture is compressed, it retains its shape.
Video "Aluminum casting in an earthen (sand) mold at home"
For parts of complex shape, a different technology is used.
Investment casting
This long-known method for making aluminum products at home can be slightly modified. The principle of casting is as follows:
The model is made of fusible material. It is laid in a certain form, poured with plaster. One sprue or several are installed. After the plaster has hardened, it is well dried. At high temperatures, the fusible material becomes liquid and flows out through the sprue. An aluminum billet is poured into the resulting mold.
The details of the process can be clarified in the video.
Video "High pressure aluminum casting"
Thus, to make the necessary part of aluminum various shapes even the most ordinary amateur master can do it.
How to cast a complex shape from aluminum
On the industrial enterprises metal molds are often used. Casting molds for casting aluminum can be obtained from various materials. Most often, gypsum is used. Gypsum can be purchased at any hardware store at any price you can afford. It is recommended to use sculptural or white plaster.
An excellent option is the sculptural one, which is marked G-16. Due to the high price, it can be replaced with G-7 - ordinary white gypsum. It is strictly forbidden to replace with alabaster, despite the fact that they are in construction work often interchangeable.
Let's consider a simple way to cast an aluminum part with your own hands at home.
To cast an aluminum part, we need:
- vessel for melting;
- scrap metal;
- mold for melting.
The main stages of the process:
1. We prepare a vessel for melting (you can use a vessel from a part of a steel pipe).
2. We make a mold for melting. If the part has a complex structure, then the form may have several components.
In our version, the form will consist of two parts. First, think about how to simplify the part for convenience (we recommend strengthening the holes with tape).
The form is very easy to make from sculptural plaster (do not use alabaster!). You can use plasticine.
3. Before pouring the gypsum, the container should be lubricated with oil so that the gypsum cannot stick to the container.
4. Gently pour the gypsum, periodically shake the mold to release the bubbles.
It's important to know: the plaster hardening process is quite fast, so be careful and try to install the model in plaster in time.
5. Requires a primary layer for the forthcoming pouring.
We take a drill and make 4 small holes, we process the form with oil. This is necessary so that the finished parts of the molds lie as stable as possible during the casting process.
6. Filling the second layer.
7. After hardening occurs, it is necessary to carefully remove the mold from the container and separate the halves.
8. Before casting, we process the mold with soot to avoid sticking of liquid aluminum. The mold needs to dry. Naturally, the drying process takes place all day. It is advisable to dry the plaster blank in the oven. Start at temperature 11 0 0 FROM- one hour and two hours at a temperature 300 0 C. Holes must be provided in the plaster for pouring aluminum and removing residual air.
In this way we melt aluminum.
9. Then we put the liquid metal into the mold and wait for it to cool completely.
As a result, we get the desired workpiece, then we grind it and make special holes.
Burnt-out casting: technology features
The manufacture of aluminum parts using burnt-out casting has its own characteristics, which will be discussed below. The work is carried out in the following sequence:
- Styrofoam is used as a material for the model at home. Using cutting elements and glue, make a figure that resembles the desired shape with outlines.
- Prepare a container for making a model. You can use an old shoe box. Mix alabaster with water. Pour the mixture into the box. Place the foam model. Smooth out. Allow time for the material to dry well. Due to the rapid process of solidification of alabaster, work at an accelerated pace.
- Remove box. Heat the mold in the oven to dry the alabaster and remove any remaining moisture. Otherwise, all the water from the alabaster will go into the aluminum and turn into steam, which will lead to pores in the metal and aluminum splashing out of the mold during work.
- Melt aluminum. Remove the molten slag from the liquid surface. Pour the metal into the mold in place of the foam. From the high temperature, the latter will begin to burn out and aluminum will take its place.
- After the metal has cooled, break the mold and remove the resulting cast aluminum model. You can see the process in more detail on the video.
Safety and workplace preparation
High-temperature work is characterized by harmful fumes and is accompanied by the release of smoke, so they must be performed outdoors or in a forcedly ventilated room. A side fan must be used.
The casting process is accompanied by splashes, flows of molten metal are possible. Workplace you will need to first cover it with a sheet of metal. It is not recommended to perform work in a residential area - it is unsafe for others.
The main mistakes in aluminum casting
Before performing aluminum casting at home, pay attention to the main mistakes that are observed during the work:
- In the manufacture of plaster molds, it is necessary that all moisture evaporate during the drying process. Otherwise, when filling the form, the water begins to evaporate, turns into steam and may remain inside the aluminum in the form of pores and shells.
- With insufficient heating, or if the aluminum has cooled down before starting work, the metal will not fill the mold well and distant areas will remain hollow.
- Do not cool metal by immersion in liquid. In this case, the internal structure of the material is violated.
Aluminum can bend like paper or be as hard as steel. Aluminum is everywhere, even within us.
Every adult gets about 50mg of aluminum every day through food, it's not a diet, it's just unavoidable.
Aluminum is the most common metal on the planet. Its content in the earth's crust is 8%, but it is not easy to extract it, at least in its pure form.
Unlike gold and silver, aluminum does not occur as nuggets or whole veins. Aluminum is 3 times lighter than iron or copper.
Aluminum in its original form is not at all like metal, this is all because of the special "love" of aluminum for oxygen.
In fact, the first use of aluminum in history occurred when Oriental potters added aluminum-rich clay to their products to make them stronger. .
Enough to make beer cans, strong enough for racing cars, flexible for aircraft skins, able to turn into anything, aluminum is an indispensable material for the modern world.
And this is not all the features that this useful metal stores.
Today we will look at how to melt aluminum cans using a simple small melting furnace at home. This time we use our high-tech backyard and a bucket of soda or beer cans. To make crafts from aluminum, or rather from cans, let's start by getting ours, which has already been made earlier, and a large bag of coal briquettes. They are usually used for barbecues. When a few coals have been distributed at the bottom of the smelter, a crucible made from a steel fire extinguisher can be added.
Just take a look at what they sell in this Chinese store.
If you place the crucible on a layer of coal, they will melt faster. Now let's attach the steel tube through the air inlet. This will provide a temperature sufficient for melting, but we still need to find a way to force air inside. For this, a household hair dryer, which can be bought at any store, is perfect.
Connect the hair dryer to a piece of PVC tubing, using two three-centimeter sleeves to attach the steel tube on one side and on the other to make it easier to detach the hair dryer. The whole structure is very easy to disassemble and place in a 20 liter bucket.
The blower is at the right angle, it does not hurt to prop it up so that it does not move away. This way you keep the walls intact and significantly increase the life of the smelter. Now that the smelter is ready, let's fill it to the top with coal. You can use a propane torch because it heats up everything very quickly. The coals are burning, so let's turn on the hair dryer on low power and send oxygen to the coals to heat everything up properly. As you can see, the lid we made retains heat and the temperature rises. The crucible and holes in the center of the lid fit perfectly.
Now let's take aluminum cans prepared for melting down and steel tongs. After 10 minutes, the smelter is extremely hot. It can be seen that the steel crucible glows orange, which means that everything is ready. The crucible is 8 centimeters in diameter and therefore great for melting cans of drinks and at temperatures over 500 degrees Celsius they melt in just a couple of seconds. We will bring the power of the smelter to full in order to melt everything as quickly as possible. The productivity of the device is on average 10-12 cans per minute.
The nice thing is that cans can be both dirty and painted, with leftover soda. It doesn't matter, as we'll see shortly, the mini-smelter absorbs everything and produces pure liquid aluminum. From experience, 35-45 cans are enough to produce 450 grams of aluminum. If you first crush the cans, then you don’t even have to remove the lid, which means that even less metal will oxidize during melting. After melting 50 cans, the crucible is full, but there is a lot of waste inside that we don't need.
A good way to insulate aluminum is to take a steel mold. To begin with, carefully pull out the crucible, making sure that it is firmly grasped with steel tongs. Then very slowly pour the melt into a steel mold. As you can see, the slag stays in the shade or acts almost like a filter, preventing solid particles from leaving it. After separating what we need, we can tap the crucible on a piece of cement and remove the slag. After cleaning the crucible, we can immediately use it again.
For fun, a few more cans were melted down to fill new form for cupcakes. The goal is to give the bars a beautiful unusual appearance. A form of steel, but sometimes a fire breaks out. This will burn off the non-stick coating. But this will only be the first time. After a few minutes the ingots begin to harden but they are still terribly hot, so hot that the paper instantly flares from them. It will be good to stock up on a bucket of water to cool them. Dropped into cold water, the ingots are still hot to boil it instantly, but after about 10 seconds, they cool down and can already be reached by hand.
Use a mini cupcake mold to make smaller ingots. The result is some very cute little cupcakes. The purpose of ingots is to have pure metal ready when you want to do something. Now, if necessary, you just need to throw a couple of ingots into a clean crucible. With this configuration, the ingots will melt in 5-10 minutes. When using ingots, we do not need to get rid of slags, except for a thin film of aluminum oxide, which means that the crucible is full of liquid aluminum ready for casting.
Let's pour aluminum into the sand, in which a special form is made, which burns out, absorbing 900 grams of liquid metal. After 10 minutes, the metal is hard enough to hook with tongs. We can break the mold and pull out our castings. At the link at the beginning of the article, you can see how the sword was cast in more detail.
When the job is done, all the accessories can be conveniently placed in a 20 liter bucket, and when the smelter has cooled down, you can easily shake out the ashes by holding the handle. Cleaning is quick and when you put a plant pot inside, the smelting furnace turns into a decoration.
Well, now you know how to turn empty soda cans into shiny metal muffins at home. You can just be proud of them and admire them, or you can use them to cast everything that comes to mind.
