PPR32-2U High-speed and high-efficiency extrusion production line of random co-polypropylene dual-pipe and dual-layer

Five Points for Attention in PVC Pipe Production

In the production process, since PVC is a kind of heat sensitive material, even if heat stabilizer is added, it can only increase the decomposition temperature and prolong the stable time without decomposition, which requires strict control of PVC molding temperature. Especially for RPVC, since its ......

Selection Method for the Screw Length-to-Diameter Ratio in Extruders

Generally, the selection can be made based on material characteristics and production efficiency.

The Impact of Extruder Screw Compression Ratio on Production Efficiency

The compression ratio of an extruder screw refers to the volume ratio between the first flight channel in the feed section and the last flight channel in the homogenization section. The compression ratio affects the production efficiency of a twin-screw extruder through the following aspects:
