PVC has been widely used in the production of cable materials because of its excellent corrosion resistance, electrical insulation, especially its flame resistance and self

After the continuous fiber bundle (carbon fiber or glass fiber) is unwound by the unwinding device, it is pre tensioned and pre dispersed by the

PVC cable material is a pellet prepared by taking polyvinyl chloride as the base resin, adding plasticizers such as stabilizer, dioctyl phthalate, diisopropyl phthalate, dioctyl

The template of the extruder is composed of a die plate body with a discharge hole and a thermal insulation layer, and is fixed to

Extruders can be divided into single screw extruder, twin screw extruder and multi screw extruder according to the number of screws. Single screw extruder is suitable for extrusion

Twin screw extruder is an important equipment in plastic processing machinery. It is not only suitable for extrusion molding and mixing processing of polymer materials,

Daily maintenance: workers need to carry out daily maintenance on a regular basis, which is generally completed when starting the machine, and does not occupy

According to the different production materials, product specifications and material consumption of customers, it is necessary to select the diameter of the screw first, and

Basic principle of screw combination For a twin-screw extruder, the screw is mainly divided into feeding section, melting section, mixing section, exhaust section and homogenization

In the process of extrusion production, gases need to be discharged from the melt. If these gases cannot be discharged, defects such as pores, bubbles
