Expert dip molding for a wide range of materials.
Matching materials to applications for optimal results.
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:
- Plastisol/PVC
- Latex
- Nitrile
- Silicone
- Neoprene
- Polyisoprene
- Polyurethane
- TPEs

Plastic Dip Molded Products
Nasal cannulae
Dip molding allows us to create complex geometries in a single component.
Stethoscope tubing
We dip mold stethoscope tubing in a wide range of colors.
Spring-reinforced cannulae
We add spring reinforcement to dip-molded arterial and esophageal cannulae to maintain flexibility and prevent crushing.
Medical balloons & cuffs
We dip mold medical balloons and cuffs for a wide range of applications including stent delivery, endoscopy, and urology applications.
What our customers are saying
One particular capability where they really stand above competitors is project management. This is done in a professional way, and we have quite high complexity involved. They are doing an outstanding job.
Global Commodity Manager / Multi-national Medical Device Company
They’ve been a good partner – good communication and meeting our needs…Open and honest. Good partnership.
Business Unit General Manager / Global Medical Device Company
The Aptyx team did an excellent job converting brass gears to plastic. Because of the design challenges, deep expertise in gears and over-molding was crucial. They also converted an expensive, labor-intensive part with quality issues to two-shot molding, which dramatically reduced cost, improved quality, and easily met the production needs. Apytx came through for us because of very good program management and good technical expertise.
Lead Principal Engineer / Global Medical Device Company
Working with your team has been one of the best contract manufacturing interactions ever. They made the whole thing happen even when it was chaos on our end.
Director of Regulatory Affairs/Product Development Manager / Medical Device Startup
The team at Aptyx is a pleasure to work with. They understand & act like true partners. I routinely hold them up as the model of the type of supplier that we need.

Dip Molding Advantages
Dip molding is convenient and cost effective, making it a popular choice for medical equipment and other applications.
Rapid prototypes
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 plastic dip molding processes and it also enables elastic wall features.
Flexible process
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.
