Alloy Metal manufactures bronze elements. Production is carried out in several ways – centrifugal casting, die casting, casting in sand molds.

Centrifugal casting.

The principle of centrifugal casting is that the filling of the mold with alloy and the formation of castings occurs when the mold rotates around a horizontal, vertical or inclined axis, or when it rotates along a complex trajectory.

By centrifugal casting, cast billets are obtained in the form of bodies of revolution:
– Bushings
– Hoops of worm wheels
– Drums for paper machines
– Rotors of electric motors
The greatest application of centrifugal casting is in the production of copper alloy sleeves, mainly tin bronzes.
Compared to solid casting, centrifugal casting has a number of advantages.

Key advantages of centrifugal bronze casting:

– Maximum material density and high wear resistance have been achieved;
– There are no scales, slag, non-metallic inclusions and air pockets in the final part;
– The parts are in the form of revolutionary bodies;
– Increased efficiency is guaranteed (range 90-95%);
– The degree of filling of cylindrical shapes increases;
– Surface roughness is minimal;
– High class of dimensional accuracy.

Die casting

Die casting is the casting of metals by the method of free casting of cooling molds.

Die casting is the casting of metals by the method of free casting of cooling molds. A die is a metal mold with natural or forced cooling, filled with molten metal under the action of gravitational forces. After solidification and cooling, the cooling mold is opened and the product is removed from it. The die can then be reused to cast the same part.
This method is widely used in serial and large-scale production.
Die casting is limited by the possibility of making large-size cooling molds and usually the weight of castings does not exceed 250 kg.
A wide range of products for all industries.

Sand casting.

Casting into sand molds is a relatively simple and economical process. In many branches of mechanical engineering (automotive, machine tool construction, car construction, etc.), this method is most often used in the mass production of castings.

Technological capabilities:
– Generally, bronze with good fluidity and low shrinkage is used as the casting material.
– The shape of castings can be quite complex, but still constrained by the need to remove the model from the mold.
– Dimensions of the casting are theoretically unlimited. In this way, the largest castings (up to hundreds of tons) are obtained. These are machine beds, turbine bodies, etc.
– The surface roughness of castings exceeds 0.3 mm, the surface often contains scales and non-metallic inclusions. Therefore, the mating surfaces of parts whose workpieces are obtained by this method are always machined by cutting.
