The principle of china Auto Shape Molding Machine
china Auto Shape Molding Machine, also known as unpacking machine, refers to the automatic completion of unpacking, forming, and bottom folding. And now the lower part of the tape is pasted, the box board that is folded into cardboard is opened, the bottom of the box is folded according to a certain procedure, sealed with tape, and then transported to the special equipment of the packing machine.
The working principle of china Auto Shape Molding Machine is similar to that of a syringe for injection. It uses the thrust of a screw (or plunger) to inject the plasticized plastic in a molten state (that is, a viscous flow state) into a closed mold cavity. Inside, the process of obtaining products after curing and shaping.
Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and taking out. After the plastic parts are taken out, the mold is closed again for the next cycle.
