The molding of the mold is quite critical. It is related to the molding effect. There are many factors affecting the molding effect. For example, the temperature, when it is usually formed, will increase its temperature and the advantages of the mold temperature increase.
1. Increase the cooling time.
2. Add crystallinity and uniform structure of the molded product.
3. Reduce the flow yin resistance during filling and reduce the pressure loss.
4. Improve the strength and heat resistance of the molded product.
5. Increase the chance of near gate location and reduce the depression of the remote gate.
6. Make the appearance of the molded product more lustrous and good.
7. The molding shrinkage is sufficient, and the shrinkage is reduced.
8. Increase the chance of burrs on molded products.
9. Reduce residual internal stress, molecular alignment and deformation.
10. Reduce the apparent extent of the bond line.
Therefore, in order to achieve a good molding effect, save time, and increase the temperature of the mold, the manufacturer often does this in order to make the molded product beautiful.
