Forming machine, also known as Open box machine is the automatic completion of the opening, forming, the bottom folding leaf bending. And now complete the next part of the tape paste, will be folded into cardboard box board open, the bottom of the box according to a certain procedure, and tape sealed and sent to the packing machine special equipment. Automatic carton forming machine, automatic box-opening machine is a large number of cartons automatically open box, automatic replacement under the lid, automatic sealing the bottom of the tape line equipment, all machines using plc display control, greatly facilitate operation, is an automatic scale production of essential equipment.

The working principle of the molding machine is similar to that of injection syringe, it is by means of the thrust of screw (or plunger), the plastic injection into the closed cavity of the molten state (that is, the viscous flow state), the process of obtaining the product after curing and shaping.

Injection molding is a cycle of the process, each cycle mainly includes: quantitative feeding-melt plasticizing-pressure injection-mold cooling-open mold pickup. Remove the plastic parts and then close the mold, for the next cycle.
