For the working principle of injection molding machine and injection syringe are similar, it is with the help of a screw or plunger of thrust, will has good plasticizing molten state (that is, the viscous flow state) plastic injection into the closed good cavity, after curing finalize the design the product process.
Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticizing - pressure injection - mold filling cooling - mold starting parts. Take out the plastic and then close the mold for the next cycle.
Operation items of injection molding machine: the operation items of injection molding machine include control keyboard operation, electric control system operation and hydraulic system operation. The injection process action, feeding action, injection pressure, injection speed, ejection type selection, temperature monitoring of each section of the feeding tube, injection pressure and back pressure regulation were respectively carried out.
