This article introduces the basic principles of twin screw extrusion of plastics, including Mechanical principles，Thermal principle，Deceleration principle，The feed acts as a coolant，In the feed zone, sticks to the barrel & slides onto the screw，Materials cost the most，Energy costs are relatively unimportant，The pressure at the end of the screw is very important，Output = displacement of last thread +/- pressure flow and leakage，Shear rate plays a major role in viscosity， and The motor is opposed to the barrel these aspects.

The twin screw extruder has a wide range of applications, and can process and produce a variety of products. We need to choose different auxiliary machines to adapt or improve the material characteristics, and make products perfect.

In the daily production of twin screw extruders, necessary maintenance work needs to be carried out on the gearbox

Q1.The length is larger than the normal pelletA: Cause of occurrence:The main reasons are: starting the machine, pulling or breaking the strip, the direction of the strip is not straight, the strip is not properly soaked in water, and the cutting tool of the granulator is worn or has gaps.Main solut

We are familiar with TPE materials as formula materials, which are composed of SEBS, plastics, filling oil, fillers, and other additives. Based on SEBS and other related materials, they all have good processing performance and an important processing process called "granulation". The granulation pro

The difference between screw vacuum pump and roots vacuum pump.

Hydraulic automatic slag discharge meshless die has the characteristics of automatic impurity discharge, no strainer, environmental protection and power saving, strengthened plasticization, no loss, and simple control.

how to clean the screw

Three-screw extruder has been well applied in the preparation of functional plastics, the preparation of high-brightness coatings and convenient food processing, and has begun to attract attention with its excellent mixing characteristics, better capacity ratio, and smaller length-diameter ratio.

Main features: The screen changer device is in the middle of the screw and before the exhaust, no matter when changing the screen at a fast or slow speed, the discharge of the machine head will normally cut off the sliver.
