Rotational molding, also known as rotomolding, is a manufacturing process used to produce hollow, seamless plastic parts by heating and rotating a mold filled with powdered thermoplastic material. As the mold rotates on multiple axes inside an oven, the material evenly coats the interior surfaces of the mold and gradually forms a uniform hollow part. Once cooled, the finished component is removed from the mold with excellent wall consistency, durability, and structural integrity. The process is ideal for producing large, complex, and stress-free hollow components with low tooling costs and flexible design capability.
Even material distribution ensures consistent strength throughout the part.
Low-pressure process reduces internal stress and enhances longevity.
Ideal for producing oversized or intricate hollow components.
Lower tooling costs compared to other molding methods for large parts.
