Designed for heavy-duty industrial plastic manufacturing, our Custom Deep-Draw Cast Aluminum Rotomolding Mold is engineered for producing large-scale hollow cubic plastic products, including waste containers, industrial bins, liquid storage tanks, and rugged protective equipment cases.

Crafted from high-density cast aluminum alloy, the core cavity ensures exceptional heat transfer, allowing uniform plastic wall thickness even in deep corners and tall side walls. The entire mold is enclosed inside a reinforced structural steel cage to prevent wall distortion and maintain strict dimensional tolerances under prolonged thermal stress.

Equipped with perimeter quick-release toggle clamps with extended leverage handles, this tooling system guarantees airtight parting line sealing, minimal flash, and fast, manual or semi-automated part demolding. We offer comprehensive OEM/ODM custom engineering tailored precisely to your 3D CAD designs, resin shrinkage parameters, and machine mounting requirements.

• Heavy-Duty Steel Skeleton Cage: Rigid outer steel framing supports high vertical side walls and prevents thermal bowing during high-temperature rotation.
• Uniform Wall Thickness in Deep Draws: Premium cast aluminum cavity provides quick, balanced thermal conductivity to eliminate thin corners in deep cubic geometries.
• High-Leverage Multi-Point Clamping: Perimeter-mounted toggle clamps with long handles ensure secure sealing and reduce operator fatigue during mold servicing.
• Integrated Mold Features: Custom-molded boss positions and insert locations for easy installation of handles, wheels, or threaded fittings.
• Full Engineering Customization: Turnkey OEM/ODM service from 3D CAD design to final factory mold trials (STEP, IGES, SolidWorks).
