Foundry Tooling Services & Solutions

A foundry is used to melt and pour metal into molds to create cast components with specific shapes, dimensions, and surface requirements. In Rotocast’s work, foundry processes support the production of thin-walled aluminum castings and tooling used in rotational molding. This is essential for manufacturers that need durable molds, consistent part quality, and reliable production performance.

Rotocast provides a focused range of foundry tooling services for rotational molding, including models and foundry patterns, aluminum castings, cast aluminum molds, finishing and framing, jigs and foaming fixtures, spare parts, and mold repair or refurbishment. These services are designed to support the full tooling lifecycle, from concept development through production support and maintenance.

Yes. Rotocast specializes in tooling for the rotational molding market. The company’s foundry tooling, castings, and mold designs are developed around the unique requirements of rotational molding, including thin wall sections, high-quality interior surfaces, accurate parting lines, and production-ready features. This specialization helps customers achieve better mold performance, heat transfer, and long-term durability.

Rotocast works extensively with aluminum for castings and molds, while also providing steel, aluminum, and stainless steel frames and spiders. Material selection depends on the tooling function, production environment, and machine requirements. The goal is to create tooling systems that balance structural support, dimensional stability, surface quality, and efficient operation in rotational molding applications.

Yes. Rotocast’s veteran pattern makers work closely with the foundry team to create new foundry patterns and make modifications to existing ones. This includes refining parting lines, adjusting production features, and supporting CNC or foam pattern production through partner shops when needed. These capabilities help customers improve manufacturability and extend the usefulness of existing tooling assets.

Yes. Rotocast provides mold repair, rebuilding, modification, and refurbishment services to restore tooling performance and extend service life. These services can address wear, distortion, damaged surfaces, or changing production needs. By repairing or updating existing molds, manufacturers can often improve output and maintain quality without replacing an entire tooling system.

Surface finish is critical because the molded product reflects the condition of the mold surface. Rotocast offers finishing options such as hand polishing, sandblasting, shot peening, acid etching, mirror polishing, and Teflon coating to achieve the desired result. Proper finishing can improve part appearance, release characteristics, and overall mold performance in production environments.

Rotocast Technologies has been in business since 1956 and has built its reputation around specialized tooling and casting for rotational molding. The company reports an average workforce experience of 16 years in specialty casting and mold manufacturing. That combination of longevity and hands-on expertise supports consistent workmanship, practical problem-solving, and dependable tooling solutions for industrial customers.
