Custom Rotational Molding for Businesses Across the USA

Rotational molding is commonly used to manufacture water tanks, industrial enclosures, medical equipment housings, agricultural products, outdoor recreation components, equipment cases, automotive components, chemical dispensing frames, automotive servicing equipment housings, material handling containers, battery boxes, pump covers, water tight remote enclosures, and many other custom plastic parts. Why choose rotational molding over injection molding?

Yes. We specialize in custom rotational molding projects designed around each customer’s unique application. Whether you have a finished CAD model or an initial concept, our engineering team can assist with design for manufacturability, material selection, tooling, prototyping, and production.

We manufacture custom rotationally molded products for a wide range of industries, including government agencies, automotive, industrial equipment, medical devices, agriculture, water treatment, energy, chemical dispensing, transportation, material handling, recreation, and consumer products. Our wide ranging experience across multiple markets allows us to recommend practical manufacturing solutions for demanding applications.

We process a variety of materials, including polypropylene (PP), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), cross linked polyethylene (XLPE), Polyvinylidene fluoride (PVDF), and polyurethane, along with specialty formulations when required. Material selection depends on factors such as chemical resistance, UV exposure, impact strength, temperature requirements, and regulatory compliance. We also offer UL94HB, V0 and V2 rated resins. Hardware can be molded into parts such as threaded inserts, colored graphics and various fittings. We can also fill parts with polyurethane foam to provide insulation properties.

Absolutely. Early engineering collaboration often reduces manufacturing costs, improves efficiencies, product performance, and shortens development time. Our engineering team reviews, draft angles, wall thickness, parting lines and assembly requirements. We try to understand the use case of each project in depth, review each project for manufacturability, highlight potential risks, and recommend design improvements before tooling is released.
