Production process
We have four methods for products designing and mould making, which is investment casting, forging, die casting and gravity casting. Investment casting includes wax pattern, ceramic shell, investment casting, cut off & grinding and shot blasting. Forging is the method that makes bar go through the process of forging, punching, T6 heat treatment and sandblasting. Die casting is the method that makes aluminum ingot go through die casting, burr removing and grinding. Gravity casting is the method that makes aluminum ingot go through gravity casting, remain removing, T6 heat treatment and sandblasting. After experiencing one of methods, material is processed into semi-finished part, then go through machining and surface treatment, the product is finished. Finally, test products and package products.
