How to extend the service life of the screw of the injection molding machine? The method to extend the service life of injection molding machine screw: 1) When the injection molding machine starts, it is necessary to fully warm up the injection molding. When the barrel reaches the pre-adjusted temperature, keep the temperature below Φ60mm for 15 minutes. After the above 30 minutes, st
What should be paid attention to if the screw barrel is not well plasticized? The screw barrel is not well plasticized and the following issues should be noted: 1. The plastic head has been cleaned or replaced! Remove the head and burn it with fire to completely burn the remaining material on the plastic head; 2. Carefully check, starting from the hopper, inner spring nozzle;
Extruder screw barrel heating and cooling Extruder screw barrel heating method: Simple heating is widely used in resistance heating, and thermocouples are used to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating mainly incl
Use conditions and methods of extruder barrel screw Extruder screw barrel heating method: Jane heating widely uses the method of resistance heating, and uses thermocouples to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating
Common materials and requirements for barrel screw Common materials and requirements for barrel screw Common materials for barrel screw: Nowadays, the most common and common barrel screw materials in my country are 45 steel, 40Cr, ammoniated steel and 38CrMOAl. The performance requirements of these materials are introduced one by one as follows: 1, 45 steel is relatively cheap
Type and design principle of injection molding machine barrel screw Type and design principle of injection molding machine screw Type of injection molding machine barrel screw: 1. Mutant Mutant screw characteristics: the compression section is short, and the energy conversion is severe during plasticization, which is mostly used for crystalline plastics such as polyolefin and
The role of barrel screw insulation The role of barrel screw heat insulation: The role of barrel screw insulation The quality of thermal insulation: Extrusion heating gas temperature: can maintain a uniform temperature, can reduce the defect rate heater life: extended twice (automatic control of heat output). The role of barrel screw insulation Insulation productivity:
Extruder screw and barrel heating and cooling methods Extruder screw barrel heating method Simple heating is widely used in resistance heating, and thermocouples are used to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating
