Will the plastic mold be affected by temperature during processing?

Plastic mold temperature is a very important part of injection molding. If the temperature of the plastic mold is well controlled, the processed product will be a good product; and if the temperature of the plastic mold is not well controlled, the processed product may be scrapped.

So, what effect will the temperature of the plastic mold have on the processed product?

1. The temperature of the plastic mold will reduce the standard accuracy of the product, which will reduce the qualified rate of the product.

2. The temperature difference between the mold core and the cavity is too large, and the plastic parts are shortened unevenly, resulting in the bending and deformation of the products and affecting the appearance of the parts.

3. The temperature of the plastic mold is too high, which will cause the product to deform during and after the molding process, reducing its shape and standard accuracy.

4. For some crystalline plastics, the use of high-temperature plastic molds is conducive to the progress of the crystallization process and prevents changes in standards during storage or use.

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

6. When the plastic mold is filled at a low temperature, if the melt rate is not high enough, the internal stress of the product will increase, which will easily cause warping deformation or application cracking, especially for some high-viscosity plastics.

7. The temperature of the plastic mold will reduce the fluidity of the plastic melt, making the parts unclear, or even dissatisfied with the mold filling, or obvious cold seams will occur due to the excessive drop in the temperature of the melt front during the mold filling process, resulting in The mechanical properties of the product decrease. Too low plastic mold temperature will also make the surface of the product not smooth and cause various surface defects.
