The essence of pressure casting is to make the liquid or semi-liquid metal fill the die cavity with high at high pressure, which is a method of forming casting under pressure.
Low Pressure Casting
Low pressure casting is a casting method of making liquid metal solidified under low pressure gas. The low pressure casting was originally used for the production of aluminum alloy castings, and further expanded its use to produce copper castings, iron castings and steel castings with high melting point.
Centrifugal casting is the technique and method of injecting liquid metal into high - speed rotating mold, which makes the molten metal forming casting with centrifugal force. The casting mold of centrifugal casting can choose non-metallic type (such as sand, shell mold ), metal mold, or resin sand mold according different casting shape, size and production batch.
Lost Foam Casting
Lost foam casting is a new type of foundry casting method which put the same size mold into a model cluster, after painting and drying, buride in the sand vibration modeling. Under negative pressure casting, the model is gasified and the liquid metal occupies the position of the model, then the casting is formed after solidification and cooling. The lost foam casting is a new process which is infinite and precise. The process needs no die, no parting surface, no sand core, no fly edge and draft angle, also reduces the size error caused by the core combination.
