How Zipper Machines work?

2022-06-25

The zipper mechines works in a similar way to syringes used for injections. It is with the help of the thrust of the screw (or plunger), the plasticized molten state (that is, viscous state) of plastic injection into the closed cavity of a good mold, the zipper mechanical internal solidification molding process to obtain products after the process.

The working principle of injection molding of zipper machinery is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticizing - pressure injection - mold filling cooling - mold pulling parts. After pulling out the plastic part, the mold is closed again for the next cycle.

The operation items of zipper mechines include control keyboard operation, electrical control system operation and hydraulic system operation. The selection of injection process action, feeding action, injection pressure, injection speed, ejection type, temperature monitoring of each section of the barrel, injection pressure and back pressure adjustment, etc.
