Injection molding is a complex process, and one mistake can cause cosmetic flaws, compromise product integrity, and lead to expensive redesigns.

In injection molding, sharp corners can cause a number of problems, including reduced strength, increased old complexity, increased manufacturing time, reduced surface finish.

After reviewing that the product design provide by the customer conforms to the molding manufacturing, the steps of mold design are as follows:

Sprue is the part of the injection mold where the melted plastic enters the cavity first, which leads the melted plastic into the runner and cavity.

Injection molding is a complex process, and the product design is the key part of the whole process. A small design issues may cause serious quality problems in molding process.

The function and structure of products will be verified by 3D printing or vacuum forming based on the first version of the product design, after several modifications to the product structure, a final design will be done.

There are six aspects we should consider in the design of injection molds.
