What are the process steps for plastic injection moulding service?

What are the process steps for plastic injection moulding service?Firstly, we need to know that there are many methods for plastic molding, and injection molded plastic products account for over 80% of molding, from daily necessities to high-tech products. Today, we will discuss the process of plastic injection moulding service and see if there is any knowledge content you are looking for.

1. Mold closing

The mold closing system drives the mold to close while applying sufficient locking force to prevent the mold from being stretched open by plastic pressure during subsequent injection molding.

2. Spray glue

The injection system heats and melts plastic particles (turning them into a molten state), and then injects the molten plastic into the closed mold cavity at high speed through a screw.

3. Maintain pressure

After the injection molding is completed, the screw continues to maintain a certain pressure and adds a small amount of plastic to the mold to compensate for the volume shrinkage during plastic cooling, ensuring that the product is full.

4. Cooling

Cooling water (or other cooling methods) is introduced into the mold to rapidly cool and solidify the molten plastic in the mold cavity, forming a shape consistent with the mold cavity.

5. Mold opening and component retrieval

After the plastic is completely cooled and formed, the mold closing system drives the mold to open, and the formed plastic product is ejected from the mold through the ejection mechanism, completing one production cycle.

The above is the process of plastic injection moulding service, hoping to help everyone. On the international stage, there is a saying that compares molds to "golden keys", "efficiency amplifiers", "the driving force for entering a prosperous society", "money printers", etc. From this, we can clearly understand the importance of the mold industry, and according to current trends and predictions for the future, the development of injection molds will be much higher than other molds.
