With the continuous development of China’s construction industry, the market demand for hard PVC pipe and its fittings is increasing. Many township enterprises have been on the hard PVC injection moulding production line. But due to the weak technical force, the production of poor product quality, high scrap rate, seriously affect the efficiency of the enterprise. This paper puts forward the common problems and solutions of PVC pipe fittings.
PVC pipe fittings parts of injection molding common problems
During the processing process of injection, molds often cannot be filled. When the injection molding machine was just started, the mold temperature was too low. The heat loss of PVC melting materials is large, and it is prone to solidification. There is a large resistance of the mold cavity, and the materials cannot be filled with cavity. This phenomenon is normal. It is just that the temporary continuous injection digital mold will disappear automatically.

Causes of problems and Solution
- The setting of the set injection is low, PVC pipe fittings. Which can improve the injection pressure appropriately.
2: The setting time is not enough, and the pressure preservation time can be appropriately increased.
3: The cooling time is not enough to increase the cooling time appropriately.
4: Insufficient solution amount, appropriately increase the amount of solution.
5: The mold is not uniform in water, and the cooling circuit can be adjusted so that the molds of the mold are evenly cooled.
6: The size of the mold pouring system is small, which can increase the portal of pouring or enlarged the main, divided, and flow tract section dimensions.
