Direct factory quotations for precision CNC-machined steel moulds, heavy-duty Rock and Roll machines, multi-arm carousels, and high-efficiency polymer auxiliary systems.
Bi-axial rotational moulding relies on the precise continuous rotation of hollow tooling along two perpendicular axes (the major primary axis and the minor secondary axis) to distribute micronized thermoplastic resin across inner cavity geometries.
Rotational speed ratios (typically 4:1, 3:1, or 1:1) dictate the dynamic trajectory of the polymer melt pool. Our CNC-controlled variable-frequency drive (VFD) architecture allows stepless adjustments from 1 to 20 RPM on both axes, eliminating dead spots and wall thinness variations in complex geometric recesses.
Engineered with dual-ducted high-velocity circulation blowers and modulated Italian Riello/Weishaupt gas or infrared heating elements. Delivers homogeneous heat flux across mold surfaces up to 350°C (±2.5°C tolerance), guaranteeing uniform layer-by-layer powder sintering without thermal oxidation or resin degradation.
Constructed from forged alloy steel heat-treated for residual stress relief. Cantilevered straight arms, offset drop arms, and dual-support C-arms are finite-element-analyzed (FEA) to endure dynamic rotating payloads exceeding 6,000 kg without torsional deflection or mechanical fatigue.
Evaluating the core competitive edge of sourcing bi-axial rotational moulding equipment from China’s leading industrial equipment manufacturing clusters.
