Will plastic molds be affected by temperature during processing?

If the temperature of the plastic mold is well controlled, the processed product is a good product; if the temperature of the plastic mold is not well controlled, the processed product may be scrapped. So, what effect does the temperature of the plastic mold have on the processed product?

1. The temperature of the plastic mold will reduce the standard accuracy and pass rate of the product.

2. The temperature difference between the core and the cavity is too large, and the plastic part shortens unevenly, which leads to bending and deformation of the product and affects the appearance of the product.

3. If the temperature of the plastic mold is too high, the product will be deformed during and after demolding, and its shape and standard accuracy will be reduced.

4. For some crystalline plastics, the high temperature application of the plastic mold is conducive to the crystallization process, which can prevent the standard erosion from changing during storage or use.

5. For plastic flexible plastics, the application of low-temperature plastic molds can reduce the molding shortening rate, improve the standard precision of parts, shorten the molding cycle, and improve production efficiency.

6. Plastic molds are charged at low temperature. If the melt velocity is not high enough, the internal stress of the product will increase, which will easily lead to warpage or application cracking, especially for some high-viscosity plastics.

7. The temperature of the Shanghai plastic mold will reduce the fluidity of the plastic melt, make the product unclear, and even make the charging unsatisfactory, or during the charging process, due to the excessive temperature drop at the front of the melt, there will be obvious cold seams, resulting in The mechanical properties of the product are reduced. The temperature of the plastic mold is too low, the surface of the product is not smooth, and there are various surface defects.
