Custom Cast Aluminum Rotomolding Mold with Structural Steel Frame & Multi-Port System for Large Rectangular Containers & Insulated Boxes

Designed for high-capacity industrial production, our Custom Cast Aluminum Rotomolding Mold is specialized for manufacturing large-scale rectangular hollow plastic products, including insulated transport boxes, heavy-duty logistics containers, utility chests, and industrial storage tanks.

Engineered with a premium cast aluminum cavity, this mold offers superior thermal conductivity for uniform wall thickness and shortened heating cycles. The mold body is fully enclosed within a heavy-duty structural steel skeleton frame, providing exceptional resistance against thermal distortion and mechanical stress during continuous high-temperature oven rotation.

Featuring an array of multi-port feeding vents on the top and perimeter-mounted quick-release toggle clamps, this tooling setup streamlines resin loading, ensures tight parting line seals, and accelerates part demolding. Fully compatible with major commercial rotomolding machines, we deliver comprehensive OEM/ODM solutions tailored to your exact CAD models and production requirements.
