Coffee Machine Filter

HY's coffee machine filters are manufactured by precision casting, also known as "lost wax casting", which involves coating the surface of a wax pattern with multiple layers of refractory materials. After hardening and drying, the wax pattern is melted to form a mold shell, which is then baked and then poured with molten steel. A method of obtaining castings. Because the castings obtained have high dimensional accuracy and surface finish, it is also called "investment precision casting."

The types of alloys produced by precision casting of coffee machine filters include carbon steel, alloy steel, heat-resistant alloy, stainless steel, precision alloy, permanent magnet alloy, bearing alloy, etc.

The shapes of wax mold castings are generally complex. The minimum diameter of the holes that can be cast in the casting is up to 2mm, and the minimum wall thickness of the casting is 1mm. In production, some individual components can be combined into integrated components. After changing the structure of the part, it is designed into an integral part and cast directly through precision casting, thus saving processing time and loss of metal materials and making the part structure more reasonable.

The production process of precision casting is relatively complex, and the materials produced and consumed are also relatively expensive. Therefore, it is suitable for the production of small parts with complex shapes, high precision requirements or difficult to perform other processing, such as turbine blades.
