The main functions of pipe extruder head are: 1) Turn the spiral motion of the molten material from the barrel into a linear motion; 2) Form the necessary molding pressure to ensure the density of the product; 3) Further plasticize the material evenly; 4) Molded products.

The head is an important part of pipe extrusion production line. Here, we briefly introduce the design principles of the head as follows:

Parallel twin-screw extruder and conical twin-screw extruder can be used to directly produce PVC-U pipe with dry powder. Due to the full engagement of two screws, a closed C-shaped chamber is formed in the twin-screw extruder. The two screws rotate outward in different directions to make the C-shape......

In the previous period, PP-C pipes and fittings appeared on the market, and the installation method was consistent with PP-R. Many people are confused about the difference between PP-R and PP-C, causing many misunderstandings and confusion. In international standards, polypropylene hot and cold wate......
