It’s used to manufacture hollow plastic bottles and containers, cases, safety products, toys, automotive parts, and many more products you see every day.

How Plastic Blow Molding Works Through the Extrusion Process

The first step in creating a custom plastic product is to work on the product design. Our in-house Design and Engineering team can create a design and mold for the product. Through the process, we choose the right material, engineer the process, assure quality, and start the production run.

We work with CAD software to produce the initial product design. After approval of the model, we create the high-quality mold to run through the process. Our lead times offer a quick turnaround.
