Metal die casting – is a production technology of castings, in which the alloy under pressure up to 700 MPa quickly fills the mold. Products made in this way can be of different sizes and have weigh up to several kilograms. As a basic raw material normally are used following: non-ferrous metals — copper, aluminum, and their alloys. Die casting makes it possible to obtain high-precision products (along with such technology as powder metallurgy, which allows to obtain sintered metal parts that are particularly hard and wear-resistant). Our company offers the manufacture of parts for LED lighting and other high quality castings. One of the main advantages of die casting is the resistance of finished products to corrosion. The fact is that in the process of their manufacture a strong surface crust is formed, which has a high density and low moisture permeability.

The vertical thin film dryer consists of a cylindrical, vertically arranged body with heating jacket and a rotor inside. The rotor is equipped with rows of pendulum blades all over the length of the dryer. The hinged blades spread the wet feed product in a thin product layer over the heated wall and mix the product layer material intensively. Therefore the volatile components evaporate continuously from the product layer with high evaporation rates. The hinged blades are designed with a minimum gap to prevent fouling of the heating surface by product, but are never in contact with the heated wall. The product enters the dryer at its top. The evaporation starts after heating to the boiling point. In the slurry zone first solids are formed and with advancing evaporation of the volatiles and continued shearing by the hinged blades the paste breaks up to powder. The final solid product is discharged by gravity at the bottom of the dryer via a suitable air lock.

Stainless steel powder 410L is a magnetic grade of stainless steel exhibiting fair corrosion resistance and decent high temperature sintering response as well as good green strength and high compressibility. 410 Steel powder is a magnetic grade of stainless steel. An excellent candidate for automotive sensor ring and mirror mount applications, P410L exhibits fair corrosion resistance and a decent high temperature sintering response. Major performance features of this stainless steel include green strength and high compressibility. Carbon Additions: Fractions of graphite can be admixed for increase hardenability in 410 SS powder. Ferritic stainless steel powdered metallurgy (P/M) technology is specified for longer-term performance and reliability. Good atmospheric and saline corrosion resistance, hot oxidation resistance and elevated temperature yield strength, at the most economical costs are key reasons for using 400 series stainless steel

Stainless steel powder 409L/409CB is a ferritic, weldable grade of stainless steel with key performance features, including high compressibility, enhanced green strength and good sinterability. This stabilized grade provides excellent corrosion resistance and has the capacity to provide high-caliber mechanical properties due to the high temperature sintering response. 409L/409CB’s versatility also results from Cb being less prone to oxidation than Ti. In addition, the oxide is unable to combine with carbon and the Cb forms a stable carbide which prevents coarsening of carbides and grains in the weld’s HAZ. 409L/409CB Stainless steel is a prime candidate for automotive exhaust system applications, among other uses. 409LNI Powder has added nickel for new automotive specifications. Ferritic stainless steel powdered metallurgy (P/M) technology is specified for longer-term performance and reliability. Good atmospheric and saline corrosion
