In the processing of plastic products, many screw barrel for Injection molding machine questions are often encountered. One of the common questions is that the screw of the injection molding machine is not fed. This kind of question: The screw i...
Corrosive, abrasive, and high-temperature resins can degrade Screw barrel before you know it. Certain engineering materials, thermoplastic elastomers, plus the wave of newly developed biopolymers, often create a corrosive condition that can quickly d...
1. After the machine has been used for a period of time, a comprehensive inspection should be done to check the tightness of all screws. 2. In case of production interruption, the main drive and heating will stop. When the power supply is restored, e...
Design principle of barrel screw of injection molding machine: The main part of the pin screw is an ordinary screw, the pin can be set in the fusion section of the screw or the drop groove of the metering section or a smooth cylindrical surface witho...
The injection molding machine screw has the following characteristics: 1. The length to diameter ratio and compression ratio of the injection screw are relatively small; 2. The screw groove of the homogenization section of the injection screw is rela...
When the injection screw is difficult to press at the feeding port, or the length of the barrel cannot form enough adhesive force to convey the material, the screw will slip. In the screw pre-molding stage, the screw rotates in the barrel to convey m...
Extruder screw and injection molding machine screw are both plastic processing machinery. They sound a bit similar, but they are actually different. There are many differences between the screw of plastic extruder and the screw of injection molding ...
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 scre...
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...
