What is the purpose of heating and cooling plastic molds? Plastic Manufacturers ，The purpose of heating and cooling plastic molds will be described below.

heating

1. Thermosetting plastics require higher mold temperature to promote the cross-linking reaction

2. Some thermoplastics also need to maintain a mold temperature of more than 80 degrees, such as polyoxymethylene, polyphenylene ether, etc.

cool down

The molding cycle mainly depends on the cooling and setting time (about 80%). Shortening the cooling time by lowering the mold temperature is the key to improving production efficiency.

Too low mold temperature will cause the following problems

 The plastic has poor fluidity, the outline of the plastic part is not clear, and the surface is dull; the thermosetting plastic is insufficiently cured, and the performance is seriously reduced.

Excessive mold temperature will cause the following problems

It is easy to cause the overflow to stick to the mold, the mold release of the plastic part is difficult, and the deformation is large; the thermosetting plastic is overcooked.
