Rotomolded Floor Machine Molds

Rotocast's thin-walled cast aluminum molds are produced with wall thicknesses ranging from 1/4 inch to 3/8 inch. This uniform wall thickness is specifically engineered to optimize heat transfer to the resin during the rotational molding process, improving cycle efficiency and part quality.

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

Yes. Rotocast provides complete product design services, engineering and pattern shop services, and custom frame design and fabrication. Our veteran pattern makers and engineering team work collaboratively to create molds for complex geometries, ensuring optimized parting lines and consistent wall thickness throughout.

Yes. Rotocast provides expert mold repair, modifications, and full mold rebuilding services. Whether your existing mold requires minor repairs or a complete rebuild, our experienced foundry team can restore or upgrade your tooling to extend its service life and maintain production quality.

Rotocast serves rotational molders and industrial manufacturers across multiple sectors, including waste management and storage (e.g., Toter, Inc., Rubbermaid Commercial Products), consumer products, and recreational goods (e.g., Swimways). Applications include hollow plastic part production, urethane forming, and vacuum forming requiring specialty aluminum castings.

Rotocast's in-house foundry uses proprietary foundry tooling and a specialized casting process developed over 70 years to pour high-surface quality, thin-walled castings with uniform wall thickness. This consistency ensures quick, even heat transfer during rotational molding cycles, reducing defects and maintaining part-to-part quality across long production runs.
