Precision Mold Pattern Casters

Rotocast's cast aluminum rotational molds are produced with wall thicknesses ranging from 1/4 inch to 3/8 inch. This precise, uniform wall thickness is critical for achieving quick and even heat transfer to the resin during the rotational molding cycle, improving cycle times and part quality.

Rotocast offers a wide variety of surface finishing options including shot peened, sandblasted textures, acid etching, hand-polished surfaces ranging from light hand-sanding to mirror polish, and Teflon coating. The appropriate finish depends on the desired surface quality of the final rotomolded plastic part and specific production requirements.

Yes. Rotocast's in-house foundry specializes in casting intricate shapes with complex geometries. Veteran pattern makers collaborate with the foundry team to optimize parting lines and ensure uniform wall thickness across even the most challenging mold configurations, making them suitable for hollow plastic parts with demanding design requirements.

Rotocast provides a comprehensive range of support services including product design services, engineering and pattern shop services, mold repair and modifications, expert mold rebuilding, technical sales support, custom frame design and fabrication, and assistance in locating qualified rotational molders — offering end-to-end support throughout a product's tooling lifecycle.

Rotocast Technologies was founded in 1956, giving the company nearly 70 years of experience in specialty casting and mold manufacturing. The company evolved from aluminum tire mold production into a specialized provider of rotational molds, applying decades of foundry expertise and proprietary processes developed specifically for the rotational molding industry.

Rotocast's molds serve rotational molding operations for hollow plastic part production, manufacturing of complex geometry products, urethane casting, vacuum forming, and production tooling where surface quality is critical. Major customers include manufacturers of commercial waste containers, consumer goods, and recreational products across North American industrial markets.
