How to solve the problem of PVC injection molding through innovative technology?

In the field of plastic processing, polyvinyl chloride (PVC) has become the preferred material for pipe manufacturing due to its corrosion resistance and economy. However, the process of PVC injection molding often leads to problems such as coking and decomposition due to heat sensitivity, and traditional injection molding equipment often cannot meet its processing needs. However, the new generation of PVC injection molding machines provides new solutions for pipe production through technological innovation.

The screw and barrel of the PVC injection molding machine are made of bimetallic alloy. By optimizing the compression ratio and screw groove depth, it can not only ensure the uniform plasticization of PVC, but also effectively reduce the shear heat generation. With the external air cooling system, the surface temperature of the barrel can be stably controlled within the standard range to avoid overheating and carbonization of the material. The PVC injection molding machine adds a larger grade oil motor to facilitate the plasticization and molding of PVC raw materials.

The upgrade of the equipment structure also reflects the humanized design. The widened safety door space provides sufficient operating space for the installation of large PVC pipe fittings molds, which is convenient for the rapid positioning of complex molds with core-pulling hydraulic cylinders. This structural optimization significantly shortens the mold replacement time. Combined with the standardized mold frame interface design, it can adapt to the production of pipe fittings of different specifications, truly realizing the "one machine, multiple molds" production capacity.
