Product 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
