What is PP PPR PE PVC pipe extruder machine?
May 06 , 2023
PP PPR PE PVC pipe extruder are available as single screw extruders and twin-screw extruders. The appropriate extruder will generally be selected according to the specific material. The material transport of single screw extruders is mainly by friction, which leads to a limited dosing performance, with powders, pastes, glass fibers and inorganic fillers being more difficult to incorporate. Further...

What is Plastic extrusion?
May 29 , 2023
Plastic extrusion is one of the most widely used manufacturing processes for plastic moulding as well as one of the most widespread manufacturing processes for thermoplastics. It is a method of forming a continuous profile with a constant cross-section by forcing a thermally melted polymer material through a head die under pressure by means of the extrusion of a screw or plunger. The extrusion pro...

Co-Extrusion Technology for Plastics Materials
Jul 05 , 2023
As the applications of plastic extrusion continue to expand, the requirements for the extrusion solutions become increasingly complicated. Many products designs require multiple functions in a simplified structure. However, each polymer material has its own characteristics and no single of them has the properties that can meet all desired needs. Therefore, the co-extrusion technology is created. C...

Plastic Pipe Extrusion Line Maintenance Recommendations
Sep 13 , 2023
1、 Extruder If replacing new raw material, please make sure the current of the main machine reaches 60%-70% of the rated current, so that the raw material can be fully plasticized. During the process, please use the vacuum pump reasonably, the host current reaches 60% or more you can use the vacuum pump. You can observe the plasticizing condition of the material through the vacuum hole of the barr...
