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...
