A process used to develop products like refrigerator magnets and vehicle bumpers, plastisol casting is a cost-effective casting method that can vary based on the product being produced.
Open mold casting and slush casting (also known as slush molding) are the two plastisol casting methods we at Piper Plastics specialize in.
Since plastisol is primarily a suspension of PVC particles in a liquid plasticizer, it flows as a liquid and can be poured into a open mold.
Because of the open mold, this process is good for items with a “flat” bottom. Common examples include:
The second plastisol casting process that we specialize in is slush molding. A more complex casting option than open mold casting, slush molding is a cost-effective alternative to injection molding that can be used to develop some plastic products.
Metal molds are used when slush casting, as these molds are not affected by heat and can allow for a faster production time than flexible mold alternatives. Metal molds are able to be used over and over again, making them a major asset to the product manufacturer.

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.
Yes! We can match Pantone colors and create custom color formulations to meet your exact specifications. We also offer various texture options including smooth, matte, textured grips, and specialty finishes. Our team will work with you to ensure your dip molded products meet your aesthetic and functional requirements.
