Kingplas blow molding machine, hollow blow molding machine has the following points for the molding process of PC material:
First, PC has a large melt viscosity and is less affected by shearing and is sensitive to temperature changes; therefore, it is more desirable to lower the viscosity by increasing the temperature during the molding process than to increase the pressure;
Second, it can cause PC degradation at high temperatures, and lines and bubbles appear on the surface of the product. Therefore, the PC must be dried before molding.
Third, the PC melt has a small shrinkage rate and uniform shrinkage when cooled, but the cooling rate is fast, and internal stress is easily generated; in order to improve the stability of the product, the raw material can be treated;
