Working principle of molding machine

The forming machine, also known as the box opening machine, refers to the automatic completion of box opening, forming, and bending of the bottom leaf. At present, the lower part of the tape is pasted, and the box board folded into cardboard is opened. The bottom of the box is folded according to a certain procedure and sealed with tape to the special equipment of the boxer. Automatic carton forming machine and automatic unpacking machine are assembly line equipment for automatic unpacking of large quantities of cartons, automatic folding of the lower cover, and automatic sealing of the bottom tape. All machines are controlled by PLC + display screen, which greatly facilitates operation and is essential for automated large-scale production devices of.

The working principle of the molding machine is similar to the injection syringe. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (that is, the viscous flow state) into the closed mold cavity. The process of obtaining products after curing and setting.

Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding-melt plasticization-pressure injection-filling cooling-opening and taking parts. After removing the plastic part, the mold is closed and the next cycle is performed.
