Polymer Molding Inc. has been manufacturing caps, plugs and custom moldings for over two decades. Our products protect threaded fittings, tubing and valves from environmental contamination and shipping damages. Working in our ISO 9001/2000 certified facility, our knowledgeable technicians and friendly customer service team provide top-quality products and efficient service with a smile. We primarily work with commodity-grade resins, and also have substantial experience with engineering-grade resins such as thermoplastics. For custom projects, we can provide engineering assistance, colour matching, insert molding, and numerous secondary operations that include bagging, hole punching and printing.

Caps Product Line

We manufacture almost twenty models of caps. End caps, available in three lengths, are designed to fit outside diameters on tubing. Tapered-style caps can also be used as plugs, and keep unwanted contamination out of pipes, valves and most other cylindrical openings. Electrical connector caps are designed to mate with male-threaded electrical connectors, but can easily be modified for other applications by removing the flange on the top surface. Our flexible silicone rubber caps conform to irregular shapes, and are designed to protect threads and tubes during painting and coating processes. We also manufacture vinyl caps, pipe caps, rectangular caps and sleeves, and more. We primarily use rubber, vinyl and low-density polyethylene.

Caps Industrial Applications

Our customers work in the automotive, aerospace, construction and fluid power industries, among many others.

Caps Manufacturing Process and Other Services

Our 50,000 square foot facility includes a high-speed lean molding cell. This area houses the latest Van Dorn closed loop systems, which produce millions of components each day and help us maintain fair prices for our customers. Our press sizes range from two to 400 tons, our shot sizes range from 2.2 to 60 ounces, and we offer horizontal and vertical molding. We also provide in-house tooling and prototyping, and mold maintenance and repair services.
