Plastic Part Rotational Molding for the Marine Industry

Jer-Den Plastics is a leading supplier of plastic rotomolded parts for the marine industry. We offer the latest rotomolding technology, tooling & equipment to provide practical, durable innovative products for our valued clients in the nautical sector.

Rotationally molded parts offer a superior alternative to traditionally manufactured steel parts. Lower weight, higher corrosion resistance and joint-free manufacturing makes rotational molding the ideal method of producing parts and components that will be used on, in or near marine environments.

Additionally, rotomolding offers greater design freedom than other manufacturing methods – allowing for the fast and affordable development of highly customized parts and specialized components. And, rotomolded parts can affordably be produced in small runs.

For marine products that require buoyancy – such as markers and mooring buoys – we also offer in-house foam pressure filling. We can add two-part marine grade polyurethane to your product to add both strength and buoyancy. Similarly we can produce boats, kayaks and canoes that are foam filled for both greater buoyancy and increased strength.

Rotomolded Parts for Boats, Ships & Yachts are Lightweight, Durable & Affordable

Rotationally molded marine components offer all of the desirable features of traditional metal products, and add substantial additional advantages.

Tanks for the nautical sector can be manufactured in virtually any size and capacity, according to your project’s specific needs. Unlike other manufacturing methods, rotational molding offers the ability to mold boat & ship tanks, and other marine products, into virtually any shape or dimension – no matter how complex or unusual – in order to optimize available space on the finished vessel.
