How to Injection Mold

Injection molding is one of the most popular and widely used manufacturing processes in the world. It is used to create a wide variety of products, from medical devices to automotive parts. Injection molding is a complex process, but it can be broken down into a few simple steps. In this blog post, we’ll take a look at how to injection mold and the different steps involved.


First, let’s discuss what injection molding actually is. Injection molding is an efficient production method that produces parts quickly, with minimal labor and waste. It is also extremely versatile, allowing for the production of parts in virtually any shape or size. This makes it ideal for producing high-volume parts with a consistent quality that meets customer specifications.

Now, let’s go over the four steps to injection molding.

Step 1: The first step in injection molding is to create a mold. This is done by using a CAD program to design the shape of the product that you want to create. The most important design considerations include part size and shape, material selection, draft angles, wall thickness, shrinkage, venting, gate location, and runner size. The mold is then machined out of metal or plastic and is used to form the product.
