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!
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.
Ergonomic, slip-resistant grips for tools and equipment
Durable end caps and protective coverings for pipes and equipment
FDA-compliant dip molded parts for medical devices and equipment
Coating for use in food grade applications

Plastisol dip molding a process whereby a dipping mandrel is dipped into a liquid polymer, typically plastisol, to eventually create a solid form on the mandrel’s external surface.
We work with a variety of materials including PVC (Polyvinyl Chloride), vinyl plastisol, natural rubber, synthetic rubber, and thermoplastic elastomers. Each material offers unique properties such as flexibility, chemical resistance, UV stability, and temperature tolerance. Our team can help you select the best material for your specific application.
Dip molding offers several key advantages: low tooling costs compared to injection molding, ability to create seamless products without parting lines, excellent for small to medium production runs, creates flexible and durable products, and allows for multiple color options and custom textures. It’s ideal for protective coatings, grips, and covers.
Lead times vary depending on project complexity, but typically range from 2-6 weeks for initial tooling and first article samples, and 1-3 weeks for production runs once tooling is approved. Rush services are available for urgent projects. Contact us with your specific requirements for a detailed timeline
We serve a wide range of industries including medical and healthcare, automotive, tools and hardware, consumer products, electronics, sports and recreation, and industrial equipment. Our dip molded products are used in applications ranging from surgical instrument handles to protective caps for automotive parts.
Our minimum order quantities are flexible and depend on the specific product and complexity. We can accommodate prototype runs as small as 100 pieces, while production runs typically start at 500-1,000 pieces. We’re happy to work with you to find a solution that fits your needs and budget.
