Some of the quality requirements are very strict products in the processing of precision injection mold processing

1) Selection of precision injection mold processing equipment

Precision injection mold processing in the choice of processing equipment usually use mirror spark machine processing, in order to ensure the high precision of injection mold, and the use of graphite electrode for EDM has more advantages, because the loss of graphite electrode is much smaller than the ordinary copper electrode.Can save a considerable part of the processing cost.

2) Selection of heating method of precision injection mold

In precision injection molding, mold temperature is also a very important parameter.For customers with high precision requirements, rapid heating and cooling systems are commonly used.

In addition, due to the precision injection molding for most of the small precision injection parts, if the use of ordinary pouring system to injection products, even after the optimization of the improvement, will produce a large number of pouring system condensate, there is still a waste of a large number of raw materials.So precision injection mold processing should use hot runner gating system.

3) Advantages of hot runner system for precision injection molds

Usually, high mold temperature is very helpful for precision injection molding, such as to prevent the defect of filling difficult thin-wall injection parts and lack of material, but too high injection mold temperature will bring new problems, such as long injection cycle and product shrinkage deformation after opening.

Therefore, it is very important to use the new mold temperature control system. In the process of injection molding, the temperature of the injection mold can be rapidly increased, so that the melt can quickly fill the cavity, to prevent the melt in the filling process of temperature reduction too fast and cause incomplete filling;

And when demoulding, precision injection mold temperature can quickly reduce, keep in a slightly lower temperature than plastic thermal deformation temperature, and then open the mold out of the product.
