Heat treatment processing precision complex mold

The method of heat treatment for machining precise and complicated molds

Are precision plastic mold specifications, shape more complex, low surface roughness and manufacture is difficult, so to explore complex precision plastic mold material selection and heat treatment problem, shunde comprehensive analysis of its working conditions, the performance, in order to improve the service life of the mold, guarantee the processing quality, reduce production cost, it is extremely important.

There is no lack of sophisticated mold in the heat treatment processing, so the processor needs to have the right method, the following to lead you to learn the heat treatment processing precision complex mold can be used.

1. Reasonable selection. To the density of the complex mold to choose good quality micro-deformation grinding steel, grinding steel with severe carbide segregation for forging and tempering shunde heat treatment, the larger or can not be forged grinding steel for the solid solution of the double refinement shunde heat treatment.

2, the design of the mold to reasonable, symmetrical shape, for larger mold to master the law of deformation, reserved processing allowance, large and sophisticated mold can be combined structure.

3. The mould shall be pre-treated.

4, reasonable choice of heating temperature and control temperature, can be used to slow heating, preheating and other balanced heating methods to reduce the mold heat treatment deformation.

5. If conditions permit, use vacuum heating and quenching and post-quenching cryogenic treatment as far as possible.
