The plastic pipe extrusion process

The plastic pipe extrusion process is divided into three stages: plasticization of raw materials；forming and Cooling forming.

Design and Construction Principle of Screw of Plastic Extruder

Feeding area of plastic extruder: the fixed groove depth of screw groove, which is responsible for preheating, plastic solid conveying and extrusion. It must be ensured that the plastic starts to melt at the end of the feeding section - that is, it must be preheated to the melting point. The general......

Calibration sleeve and its function

The calibration sleeve is a component that assists the cooling and shaping of plastic pipes in the extrusion production of plastic pipes. It is installed at the front end of the vacuum calibration machine. After the pipe comes out of the mold, it enters the vacuum tank and spray cooling tank for fur......

Type of extruder screws

A screw with excellent performance should not only have high output, but also have a plasticizing effect that meets the product performance and a good comprehensive performance of temperature, pressure and speed. Therefore, a variety of new screws have come out one after another, which greatly impro......

Main parameters of the single screw extruder

Screw refers to the metal rod with screw groove that can rotate in the barrel of extruder or injection molding machine. Screw is the most important part of extruder to transport solid plastic, plasticized plastic and melt, which is often called the heart of extruder. Through the rotation of the scre......

Problems and solutions of extruder in the production process of insulation pipe equipment

Plastic extrusion has always been an important link in the production process of insulation pipe equipment, which is not only related to speed but also to quality, and the extruder plays a decisive role in this link. Ningbo Fangli Technology Co., Ltd. has summarized a series of experience from theor......
