Investment casting, also known as lost wax casting, is a traditional manufacturing process that originated thousands of years ago. This process is utilised to create metal parts and components with complex shapes and intricate details. It is a cost-effective method to produce complex parts.
The process commences with the crafting of a wax or plastic pattern, an exact replica of the desired part. Our experienced engineers excel in designing tooling for creating these patterns. Once the tools are devised, we utilise 3D printing for initial rapid prototyping, which undergoes testing before the production phase. Subsequently, the pattern is coated with a ceramic slurry to form a shell around it. After the shell has hardened, the wax or plastic is melted out, leaving behind a cavity in the shape of the desired part. Molten metal is then poured into the cavity, filling the space vacated by the melted pattern. Following solidification, the ceramic shell is removed, revealing the finished metal part. Investment casting is esteemed for its capability to produce parts with tight tolerances, excellent surface finish, and intricate geometries.
Here at A & M Manufacturing Company Ltd, we possess the capability to manufacture metal parts and components with extremely tight tolerances and complex and intricate shapes and designs, both internally and externally. We can cast metal parts and components with a wide range of materials using the investment casting technique, including stainless steel, carbon steel, cast iron, aluminium, and many more.

Structural characteristics of the chip ball valve
Structural characteristics of the chip ball valve: 1, opening and closing without friction. This function completely solves the problem that traditional valves affect the sealing due to mutual friction between the sealing surfaces. 2, the body structure. Valves installed in the pipeline can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs. 3, single seat design. Elimination of the valve cavity medium due to abnormal pressure and affect the use of safety issues. 4, low torque design. Special structure design of the valve stem, just with a small handle valve can easily open and close. 5, wedge seal structure. Valves rely on the mechanical force provided by the valve stem, the ball wedge pressed to the seat on the seal, so that the valve seal from the impact of pressure changes in the pipeline under various conditions, the sealing performance has a reliable guarantee. 6, self-cleaning sealing surface structure. When the ball is away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball evenly, which not only eliminates the local erosion of the valve seat by the high-speed fluid, but also rushes away the accumulations on the sealing surface to achieve the purpose of self-cleaning .
