Expert dip molding for a wide range of materials.
Dip molding is the process of dipping a mold into a polymer solution to create a molded component. Our most commonly used dip molding material is plastisol (a suspension of PVC particles in a plasticizer) because it is a well-proven and cost effective material. When heated, plastisol fuses and is converted into a tough, homogeneous material with excellent resistance to abrasion, aging, corrosion, and electrical resistance. It can be compounded in almost any hardness, clarity, and color, and can be pumped or sprayed. With decades of materials expertise, we can work with you to identify the best material for your dip molding project.
Materials we commonly work with include:

Plastic Dip Molded Products
Dip molding allows us to create complex geometries in a single component.
We dip mold stethoscope tubing in a wide range of colors.
We add spring reinforcement to dip-molded arterial and esophageal cannulae to maintain flexibility and prevent crushing.
We dip mold medical balloons and cuffs for a wide range of applications including stent delivery, endoscopy, and urology applications.
Dip Molding Advantages
Our manual dip molding cells are set up to accommodate rapid prototypes. Though tooling is necessary, tooling costs and lead times are much less compared with other molding processes.
Lower tooling costs
The tooling costs and lead times for dip molding tooling are substantially less than other custom polymer manufacturing processes.
Complex & elastic geometries
The dip molding process enables us to produce complex geometries more cost-effectively than with other molding processes and it also enables elastic wall features.
Due to the flexibility of the dip molding process, it is easier to achieve a wall thickness that is much thinner or thicker than with other plastic manufacturing processes. It’s also easier to accommodate changes–such as adjusting wall thickness–after tooling is completed.
