Алюминий нашел широкое применение в современном world. This metal is characterized by light weight, ductility and ductility, which allows it to be used in many industries. The melting point is 660 ° C. In production, aluminum casting is often used, thanks to which all kinds of parts are made.
Aluminum has been melted for a long time. He easily acquires any
form, so it is simply irreplaceable in the worldindustry. Today, many steel companies use high pressure die casting technology. It is created in a special chamber by means of a piston, on which compressed air, emulsion or oil accelerates the movement. The molten metal enters a high-strength steel mold at a speed of about 50 m / s, which ensures its absolute filling.
Die-casting of aluminum has a massadvantages, among which not only increase in productivity, but also high accuracy of the finished product. The technology is used to produce important parts in instrument making, mechanical engineering and aircraft building.
An uncomplicated part of this metal can be done by yourself. Everything you need for this is found in the home workshop.
In the process, the following tools will be needed: a wooden spatula, tweezers, hooks, scalpels, brushes, brushes and a trowel made of high-quality steel and having a smooth surface.
Aluminum casting at home means pouring metal into molds. They can be made from a wooden box.
Forming of the future part takes place in two moldings (frames). To make them,
You need to remove the bottom and lid of the box and cut it withusing a longitudinal saw to two different parts in height. In the resulting flasks you need to drill two vertical holes on opposite walls and insert coke rods into them. When the drawer is closed, the coke that protrudes from its lower part must enter the holes drilled in the upper frame. This allows you to accurately fix the flasks relative to each other.
When the casting mold is properly manufacturedaluminum in the ground should result in a cavity that will completely copy the molded part. It is done by pressing one side of the product copy into the ground of the upper flask, and the second - into the surface of the bottom. The frames must rest on a strong shield. A copy of the part can be made of wood or polystyrene.
The filling of the molding earth must occurgradually. Each new layer should be well compacted, otherwise the sifted earth will not keep its shape. It remains to make a few gas vents and insert the gate, through which the molten metal will flow. Now you need to let the earth dry well.
Before you finally assemble the form, you must carefully inspect it and
make sure there is no clump of land.Casting aluminum will give an excellent result only if the groove will ideally repeat the product. The joint formed between the lower and upper flasks, it is recommended to cover with clay, so that the liquid metal does not pour over the edges of the depressions. After that, the top molding is superimposed on the bottom and fixed with cokes.
Aluminum must be melted in a tin can, by placing it on a burning stove. When the metal ceases to stick to the poker lowered into it, it can be removed from the fire and poured into the mold through the gate.
After waiting for the cooling, it is necessary to extract the part from the ground. Usually after this, additional processing of the product is carried out, including cutting off excess projecting edges and grinding.
Casting aluminum is a very fun and rewarding process. Thanks to this technology, small parts can be made independently, which will allow you to get pleasant emotions and save money.
