The injection molding machine is currently used more and is more common, but how does it work? Let's take a look!
The working principle of the injection molding machine is similar to that of the needle for needle injection. It is based on the thrust of the screw (or plunger) to inject the plasticized molten state (ie, the viscous flow state) into the closed cavity. The process progress of the product is obtained after curing and setting.
Injection molding is a cyclic process, and each cycle includes: quantitative feeding - melt plasticization - pressure injection - filling mold cooling - mold extraction. After removing the plastic part, the mold is closed again for the next cycle.
Injection molding machine operation items: Injection molding machine operation items include three aspects: control keyboard operation, electrical control system operation and hydraulic system operation. The injection process action, the feeding action, the injection pressure, the injection speed, the selection of the ejection type, the monitoring of the temperature of each barrel, the adjustment of the injection pressure and the back pressure are performed.
