The working principle of the lunch box injection molding machine is similar to that of a syringe for injection. It is a process of injecting plastic into a closed cavity in a molten state (that is, a viscous flow state) with the help of the thrust of the screw (or plunger).
Injection molding is a cyclic process. Each cycle mainly includes quantitative feeding, melt plasticity, pressure injection, mold filling and cooling, and mold opening. Take out the plastic part, and then close the mold for the next cycle.
Lunch box injection molding machine operation items: The injection molding machine operation items include control keyboard operation, electronic control system operation and hydraulic system operation. The injection process action, feed action, injection pressure, injection speed, injection type, and each cylinder are respectively carried out. Section temperature monitoring, injection pressure and back pressure adjustment.
