How to Configure Twin Screw Extruder丨Melt Section Screw Specs
The melting mechanism of a co-rotating twin-screw extruder is special. The single screw process relies on heat from the barrel and friction between the polymer transported between the barrel wall and the screw threads. And the twin screw extruder mechanically process the polymer with a kneading block to stretch, shear, and fold the polymer to… Continue reading How to Configure Twin Screw Extruder丨Melt Section Screw Specs

About temperature controlling of the extruder,what is the difference between water cooing and fan cooling?
As we know,temperature is one of the necessary conditions for the extrusion processing , and the heating and cooling system of the extruder is to ensure the temperature condition. There are two ways to earn heat in the extrusion processing,one is the heat supplied by the external heater of the barrel, and the other is… Continue reading About temperature controlling of the extruder,what is the difference between water cooing and fan cooling?

Two key points of energy vehicles: power battery and lightweight
At present, the early stage of the reform of the automobile industry is mainly electrification. During this period, the core components of the car are no longer the “three big parts” (engine, gearbox and chassis), but the three-electric system (battery, motor and electronic control), accounting for more than 50% of the cost of new energy… Continue reading Two key points of energy vehicles: power battery and lightweight

Detailed use of thread element of parallel double screw plastic extruder
Characteristics of parallel plastic twin screw extruder: 1. High speed and close relative motion speed in different positions of the engagement area (the two screws overlap in the cross-section diagram), so strong and uniform shear can be generated; 2. The geometry dictates that the longitudinal runners must be open to allow for the exchange of… Continue reading Detailed use of thread element of parallel double screw plastic extruder
