PVC Molding in China: Leading Chinese PVC Molds Manufacturer – Suntechmold

PVC molding is becoming increasingly popular in the building industry due to its excellent corrosion-resistant properties, particularly for products like PVC pipe fittings. At Suntechmold, we are committed to providing high-quality PVC molds and sharing valuable insights on the best practices for PVC molding.

Key Considerations for PVC Molding

Avoid Burning PVC:
PVC releases acidic fumes when burned, which can be hazardous. Therefore, it is crucial to avoid using hot runners in PVC molding. Instead, we use edge gates, considering that the melting flow of PVC is not very fluid.

Use Special Equipment for PVC Molding:
Due to the release of corrosive acid gases during the molding process, both PVC molds and injection molding machines require specialized materials and designs to prevent damage. At Suntechmold, we use high-grade stainless steel, such as DIN1.2316, for PVC molds to resist corrosion. Additionally, our machines are equipped with specially designed screws and fans to control temperature, addressing the shear sensitivity of PVC materials.

Enhancing Safety in PVC Molding:
PVC molding can release acid gases that are potentially harmful to workers. At Suntechmold, we have developed effective measures to minimize the exposure to these gases, significantly enhancing safety and production security.
