7/9/12 -- Six Steps to Plastic Injection Molding

Plastic injection molding is the process responsible for thousands of products that we use today, from tiny automobile parts to your child’s favorite toy. Almost 30% of all plastic products are made using an injection process, making it one of today’s most common plastic manufacturing methods. Plastic injection molding is ideal for the mass production of parts and produces components for hundreds of industries, including aerospace, medical, automotive and construction.

At Atlanta Plastic Injection Molding, we have streamlined the six-step plastic injection molding process for any type of plastic part that you need.

First, our engineers and developers design a mold prototype using CAD software. At APIM, our design department specializes in developing molds for the parts you need. Once the prototype is approved, a mold is constructed out of metal.

Next, polymer (plastic) pellets are fed into a large, open-bottomed container. Once inside, the plastic pellets are pushed through grooves, creating pressure and producing heat. This heat inside of the cylinder melts the polymer and prepares it for injection into the mold.

An auger, or large screw, on the machine injects the polymer melt into the mold using high pressure force. After the plastic solidifies, the mold is cooled either by air or water circulation.

The clamp holding the mold closed is then released and the plastic part can be removed, cleaned, and assembled if necessary.
