Custom Rotational Mold for Special-Shaped HDPE Fuel Tank & Engineering Machinery

OEM ODM Rotomoulding Mold for HDPE Complex-Shaped Fuel Tank & Special Machinery Oil Container is a high-precision rotational mould independently designed and manufactured by SUNMORE factory. It is specially used for one-piece rotomolding of HDPE complex-shaped fuel tanks, non-standard oil containers and special equipment fuel vessels. Made of high-quality cast aluminum alloy, this mould features excellent thermal conductivity, uniform heat distribution and high dimensional accuracy. It is suitable for mass production of customized fuel tanks, meeting the diverse needs of engineering machinery, special vehicles, heavy equipment and industrial vehicles.

Poor thermal conductivity leading to uneven wall thickness: Conventional moulds often have uneven heating in complex shapes, resulting in thin and weak areas on the fuel tank that are prone to cracking or leakage. Our high-grade aluminum alloy mould ensures uniform heat transfer, making the tank wall thickness consistent and pressure-resistant even in complex geometries.

Rough inner cavity affecting sealing performance: Ordinary moulds may leave scratches or burrs on the tank surface, especially in hard-to-reach areas, which can affect the sealing and durability of the fuel tank. Our precision CNC machined mould produces smooth, burr-free fuel tanks with high surface quality in every corner directly from the mould.

Difficult demoulding and low production efficiency: Complex mould structures with multiple undercuts can make demoulding slow and damage the product. Our optimized split design with quick-release clamps and precision alignment allows for fast assembly, disassembly and demoulding, significantly improving production efficiency even for complex shapes.

Low wear resistance leading to short service life: Common moulds wear out quickly after repeated use, especially in complex contact areas, causing product defects. Our mould undergoes professional anti-corrosion and anti-wear treatment, maintaining high precision for tens of thousands of cycles.
