1. The working principle of the pressure forming machine is as follows:
The working principle of the pressure forming machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous flow state) into the closed mold cavity. The process of obtaining products after curing and shaping. Injection molding is a cyclic process. Each cycle mainly includes: quantitative feeding-melting and plasticizing-pressure injection-mold filling and cooling-mold opening and part removal. After taking out the plastic part, the mold is closed again for the next cycle.
2. The operating method and process of the pressure forming machine are as follows:
Clamping → Pre-molding → Reverse → Nozzle advance → Injection → Hold pressure → Nozzle retreat → Cooling → Mold opening → Ejection → Open door → Take workpiece → Close door → Close mold.

The forming machine, also known as the box opening machine, refers to the automatic completion of box opening, forming, and bottom folding. And now the lower part of the tape is pasted, the cardboard box is opened, the bottom of the box is folded according to a certain procedure, and the tape is sealed and sent to the special equipment of the boxing machine. Automatic carton forming machine and automatic carton opening machine are assembly line equipment that automatically opens large quantities of cartons, automatically folds the lower cover, and automatically seals the bottom tape. The machines are all controlled by PLC + display screen, which is greatly convenient for operation and is essential for automated scale production. device of.
