Casting Technology
Our factory provides sand casting, metal casting, centrifugal casting, and other casting processes to meet the performance requirements of various casting products.

Centrifugal casting has the capacity of producing large copper bushing, copper bushing, and copper worm gear. In this process, the product density is good, the hardness of copper casting, tensile strength, wear-resistance, and other mechanical properties are far higher than the molding processing copper casting. Self-lubricating products with the most excellent quality, perfect service, low price sales win the market.

Centrifugal casting is to pour liquid metal into a rotating cast, solidification formed copper casting axis and the axis of the rotating cast coincide. Under the action of centrifugal force, the metal crystallization from the casting wall to the inner surface of the casting sequence, directional crystallization, slag, gas, inclusions and others concentrated in the inner surface of the casting, the other parts of the casting structure is fine, no pores, shrinkage holes, slag inclusion defects, and fine structure, so the mechanical properties of the casting is good; Centrifugal casting does not need pouring system, no consumption of molten metal at risers and other places, and the core can be omitted when casting hollow castings, so the equipment investment is less and the efficiency is high.
