The main factors affecting the quality of plasticization are: aspect ratio, compression ratio, back pressure, screw speed, barrel heating temperature, etc. 1. Length-to-diameter ratio: the ratio of the effective working length of the screw to the scr...
The extruder barrel screw is not well plasticized because the solid phase cannot flow like a fluid, so the heat generated by shear is small. The heat source of solid phase melting mainly relies on the heat source conducted by the heater on the barrel...
The screw barrel for Injection molding machine is working for a long time under high temperature, high pressure, high mechanical torque and high friction environment. The first few factors are required by the process conditions, and the loss caused b...
The injection screw is the core component of the injection molding machine, and the screw has been working under high temperature, high pressure, high mechanical torque and high friction environment for a long time, and the wear problem is inevitable...
Generally, the screw of the injection molding machine has undergone nitriding treatment to increase the surface hardness, that is, to improve the wear resistance. However, if you neglect to cause the injection molding machine screw to work under high...
The barrel and screw constitute the extrusion system. Like the screw, the barrel also works under high pressure, high temperature, severe wear, and certain corrosion conditions. In the extrusion process, the barrel also has the function of transferri...
People use high-speed injection molding machines to shorten the injection cycle and improve production efficiency. However, in the production process of injection molding products, the slippage of the injection molding machine screw is a big problem....
In the injection molding process, the screw of the injection molding machine is often stuck and does not rotate. Usually, if the screw protection device of the injection molding machine does not work, the operator should stop it immediately. In many ...
