At Piper Plastics, we specialize in using a process called dip molding to create plastic parts for companies in a variety of industries. But that’s not all that we do here. We also utilize another process called dip coating that is similar to dip molding, but with a slightly different end result.

You’ve probably seen tools like pliers and wrenches that have a plastic sheathing on the handle which makes them more comfortable to use. This extra layer of plastic was added to the tool during a process called dip coating.

During the dip coating process, the original part acts as a dipping mandrel. It is preheated and dipped into plastisol before being heated again. As the plastisol cools, it forms a solid protective coating on the outside of the part. This coating can be made in just about any color, and it can even offer thermal and electrical insulation for your parts. The plastisol dip coating process takes place very quickly, but it will have a big impact on the overall form and function of your product.

An Introduction to Dip Coating

Using your part as a dipping mandrel, it is carefully preheated, dipped into plastisol, and post heated. After cooling, a colorful, comfortable, and conformal coating is created on your original part. Dip coating your parts requires virtually no tooling cost; offers competitive piece price; and produces parts that are comfortable and protected. 

The plastisol used can also provide thermal and electrical insulation for your parts, and it naturally inhibits oxidation.
