The Dip Coating Process

Dip coating and dip molding are the essentially the same process, however, in dip coating, our customers supply us with the dipping mandrels, (which are actually the parts they want coated,) and we don’t remove the plastisol after the parts cool.

Everything else is the same as dip molding with plastisol, with the following exception:

When Piper Plastics dip coats your products, you have the option of asking us to use a pre-processing technique, called priming, which makes the vinyl adhere to your parts, forming an incredibly tight bond.

In fact, if you try to remove a plastic coating from a properly primed part, you will actually tear the vinyl itself before it detaches from the metal. Technically, this means that the adhesion of the PVC to the metal substrate is GREATER THAN the cohesion of the vinyl itself!

This process is so effective it’s specified by the US military in its A-A-59464 (formerly MIL-P-20689) plastic coating specification.

  • Even without this priming step, a plastisol dip coating is still an effective method to add functionality, color, texture, safety, electrical insulation, comfort, and beauty to your parts.


Plastisol dip coatings can be applied to many different products in order to supply them with aesthetic qualities, tactile softness, and gripping power. 

For instance, tools like pliers and screwdrivers are often fitted with plastisol dip coatings on their handles in order to provide the user with a solid grip instead of sheer metal.
