7 Steps In Plastic Injection Molding Service
7 Steps in the plastic injection molding process cycle:
Plastic resin is supplied in raw granules. They are dried to the correct water content, and then if needed, they can be mixed with coloring masterbatches or pigments.
The dried granules are placed in the feed hole of the molding machine. An alternative screw inside the machine barrel will carry these materials to the mold while
heating them.
Every half of the mold is fixed to the injection molding machine. A half is permitted to be moved. The hydraulic clamping unit pushed the mold halves together and exerts enough force to hold the mold tightly shut while the granules are injected. These two partial mould will be pushed together by the hydraulic system in order to hold the mold tightly shut while the granules are injected. The time it takes to close and tighten the mold depends on the machine-large clamping forces) will take longer.
The injection molding pushed raw material into a mold. In this process, the melted plastic is then injected into the mold very rapidly and the pressure packs build up and hold the material. The injection time is hard to calculate precisely because of the complex and changing flow of melted plastic in the mold. But it can be estimated depending on the volume injected, the pressure, and power.
The melted plastic inside the mold starts to cool when it touches with inside surfaces of the mold. While the plastic cools, it will freeze in the shape of the required part. But there may be some appear sink marks on the part in the cooling. Packing the material at the injection enables an extra material to drain into the mold and reduce the amount of visible shrinkage. The mold can't be opened unless the necessary cooling time has passed.
These two halves of mold will be split by a hydraulic system as well.
Once the time has elapsed, the cooled part can be ejected from the mold through the ejection system which is fixed to the back half of the mold. Once the mold is opened, the part will be pushed out by the mechanism. The force must be suited to eject the part as when cooling, the workpiece shrinks and adheres to the mold.
Plastic injection Molding Application
-Packson plastic injection molding company cercitified with ISO9001, ISO13485 and equipped with ISO 8 medical cleanroom molding.
-Rapid processing mold with low cost and enable to make plastic injection molding products with 10 days at a competitive price.
-Moulded part is a good way for low quantity production from dozen to hundred of the part even millions of parts. The molding part is better than the part machined by CNC or 3D printing with the same material. The right choice for resin used in the molding part allows for a wide range of properties. Mold is essential for plastic injection molding medical parts. So molds machined by CNC and Wire cut EDM with high precision and tolerance are enable make thousands of parts.
