Zinc alloy products are used in various fields of industry and everyday life. Alloys from this raw material have increased ductility. And this property makes it possible to use it to obtain castings of complex shapes with the thinnest walls. Zinc casting of rolled metal does not react with metal and cannot stick to its area.
Zinc alloy castings have low area roughness, dimensional accuracy. The blanks, which are obtained by injection molding, are perfectly processed by pressure and cutting.
The main methods of zinc casting
In non-ferrous metallurgy, there are a couple of ways to create a casting, and this can make the work of the technologist a little difficult, especially in identifying how the element is made. Before making an effective choice in favor of a particular technology, you need to understand the following:
The selected casting method must ensure that the resulting elements fully comply with the regulatory and technical and working documents. Everything, the characteristics that are included in the element will be taken into account.
The application of the selected technology should be based on the use of existing equipment and equipment.
To obtain zinc alloy castings, these main types of castings are used, in addition, their features must be taken into account. For example, zinc casting. However, one must take into account the fact that after sand casting it will be useful to carry out additional processing of the area, because its quality is not as high as we would like. In production conditions of small batches of elements, it is worth thinking about die casting. However, in this regard, the increased price of equipment may be an obstacle.
The result of the improvement of foundry technology was the emergence of technology to perform centrifugal zinc casting to order. The principle of this method of obtaining a casting is simple – the melt is fed into molds that rotate around their axis.
There is a technique of horizontal and vertical impact. They are used to make castings with huge dimensions.
This technology makes it possible to obtain hollow castings, moreover, it does not require the use of an additional device, for example, a rod. And experience is not required. The casting, which is obtained using this technology, has a dense and fine-grained structure of the material. In addition, due to a number of reasons, in particular, due to the slight compliance of the form, defects are likely to occur.
However, the chill mold has a high price due to the increased complexity of its production.
The increased cooling rate causes the melt flow to decrease and this usually results in a defect. Zinc alloy casting individually under pressure makes it possible to obtain difficult products with minimized wall dimensions. The quality of the resulting goods makes it possible to avoid subsequent mechanical processing. Such casting differs in the level of productivity. However, to guarantee it, expensive equipment is needed. In addition, there are restrictions on the size of the molded part.
In the metallurgical field, in rare cases, castings are made from pure metals. In addition to a few highly specialized areas, products made of pure zinc are practically not used. Our company can perform casting of zinc alloys and perform excellent quality casting of various forms from ZAM alloys.
Where does it apply?
The main areas of use of TsAM — production of fittings for doors, carburetor housing, pump, decorative parts, and type casting area. Zinc elements are very durable and can perfectly follow the relief of forms, for this reason we are ready to produce a cast with an already applied picture and small elements.
