Factors Affecting The Metamorphic Layer Of The Middle Wire Cutting

Factors Affecting The Metamorphic Layer Of The Middle Wire Cutting 1. Metallographic structure and elemental composition of the workpiece material Due to the discharge of the electric spark, the metallographic structure of the surface layer of the workpiece material changes significantly, forming a discontinuous, uneven thickness of the metamorphic layer. It is related to the…

What Is Vacuum Casting?

What Is Vacuum Casting? Vacuum casting is a process that uses a ventilated mold. The molten metal flows into the mold by air pressure and then removes the air to form a vacuum. This casting method is mainly used for small parts or jewelry with intricate details. It is a physical modeling method. The vacuum…

Mold Surface Strengthening Treatment

Mold Surface Strengthening Treatment In recent years, with the development of industry, the requirements for product quality have become increasingly strict, and the requirements for molds have become higher and higher. In particular, precision die-casting molds require a high degree of mechanical properties, and require a small amount of deformation, which is basically no longer…

Die Casting Mold Performance Requirements

Die Casting Mold Performance Requirements Pressure casting can cast parts with complex shapes, high precision, small surface roughness and good mechanical properties. Therefore, the die casting mold should have the following performance requirements: (1) Large high temperature strength and toughness The die-casting mold is subjected to high temperature, high pressure and thermal stress when molten…
