A draft angle is the angle applied to the vertical wall of an injection molded parts to assist with releasing the part from the mold.

A plastic injection molding machine is a manufacturing machine designed to turn plastic polymers and resins into plastic parts and products. The injection molding process will essentially heat plastic material to its melting point, and the injection unit will force it into a created mold. Once in the mold, the part or product will harden as it cools, and the solid product will be ejected.

How to set the ejector pin?

The production cycle of an injection mold project is generally 40 days, and the communication between the supplier and the customers in the beginning directly determines the progress of the project. The following are some details of the mold project. If this data is fully provided, it will save lots of time on information exchange.

Some preparation before injection molding

The structure of an injection mold depends on the design of the plastic part, so how to manufacture a qualified injection mould?

Injection molding machines are often shut down when something happens and restarted. What should be kept in mind to avoid affecting the injection molding?

Anyone with some knowledge of injection molds will know that there are plenty of holes around the mold. What are the functions of each hole?

Injection molding is a process of forming molten material into plastic parts of a specific shape. To ensure the quality of injection molding, adequate preparations should be conducted before molding. So, what are the preparatory works?

Since engaging in the molding industry, we have come cross many customers who have this understanding: plastic molds are used to produce plastic products, stamping die are used to produce metal parts, and their working principle is similar.
