Materials of BAI commonly used in die making: T7, T8, T12, 6CrW2Si, 5CrMnMo, Cr12, Cr12MoV. The use of the mould DU zhi road is different, the choice of the mould material is different.

1. The mold is a tool to make the blank into a piece with specific shape and size under the action of external force DAO. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, ceramics and other products of pressure molding or injection molding forming processing. The mold has a specific outline or cavity shape, and the blank can be separated (blanked) according to the outline shape by applying the outline shape with a cutting edge. The shape of the blank can be obtained by using the shape of the inner cavity.

2, the mold generally includes moving mold and fixed mold (or punch and die) two parts, the two can be divided and can be combined. Take out the parts when separate, and inject the blank into the mold cavity when close. Mold is a precision tool with complex shape, bearing billet expansion force, and has higher requirements on structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important marks of mechanical manufacturing level.


Is located in the hometown of molds in China - the intelligent mold town of Huangyan, Zhejiang. Form a core team partner mechanism. The team adheres to the development concept of "small and specialized, specialized and refined...
