The screw of the injection molding machine works under high temperature, high pressure, high mechanical torque and high friction environment for a long time. The first few factors are required by the process conditions, and the loss caused by friction is inevitable. Generally, the screw has been sub... Read More
Material performance 1. The material performance of the Granulation screw is mainly manifested as excellent electrical insulation (especially high-frequency insulation), white hard and brittle, metal sound when dropped on the ground, light transmittance second only to organic glass, coloring and wat...

In the pre-plasticizing stage of the screw, the screw rotates in the barrel 100 to convey the material along the direction of the screw and back up to accumulate the material for the next injection, the screw will also slip. If the screw starts to slip during the pre-plasticizing stage, the axial mo... Read More
The application of the Screw barrel of injection moulding machine is more divided into: integral degree, segmented type, bushing type, casting type, bimetallic layer barrel. Integral barrel: Most injection molding machines and extruders are monolithic barrels, especially small and medium models, bas... Read More
The last thread of the material mouth starts to call the conveying section. The material here cannot be plasticized, but it must be preheated and compacted. In the past, the old extrusion theory believed that the material was loose. Later, it was proved that the material is solid Stopper, that is to... Read More
