Description
Custom Rotational Mold for HDPE Single/Double Kayak Hull & Water Sport Boat
Product Overview
This high-precision aluminum rotational mold is independently designed and manufactured by SUNMORE factory for one-piece rotomolding of HDPE single and double kayaks, recreational canoes, and water sport boat hulls. Constructed from high-quality cast aluminum alloy, the mold delivers excellent thermal conductivity, uniform heat distribution, and high dimensional accuracy, making it ideal for mass production of various kayak types to meet diverse outdoor water sports requirements.
Problems We Solved
  • Poor Thermal Conductivity: Our high-grade aluminum alloy mold ensures uniform heat transfer, eliminating uneven wall thickness and enhancing structural strength and impact resistance.
  • Surface Defects: Precision CNC machining produces smooth, seamless, high-gloss kayak hulls that reduce drag and improve water performance.
  • Demoulding Challenges: Optimized split-type structure with precision positioning and quick-release clamps enables fast assembly, disassembly, and damage-free demoulding.
  • Wear Resistance: Professional anti-corrosion and anti-wear treatment ensures the mold maintains high precision and smooth surfaces through tens of thousands of cycles.
