Rock and Roll Rotomolding Machine 3m–12m Length for Kayak Boat Pipe and Long Hollow Plastic Products
Product Overview
Rock and roll rotomolding machines are specifically designed for manufacturing long and cylindrical hollow plastic products such as kayaks, boats and pipes.
Unlike standard biaxial rotation systems, this machine combines rocking motion with rotational movement, allowing material to distribute evenly along elongated molds.
This structure is particularly suitable for products where length significantly exceeds diameter.
Working Principle
The molding process begins with polymer powder loaded into a long mold.
During heating, the mold rotates along its longitudinal axis while simultaneously rocking back and forth.
This combined motion ensures that molten material flows evenly across the entire inner surface, even in extended geometries.
The result is a uniform wall thickness throughout the length of the product.
Applications
Kayaks and recreational boats
Fishing boats and aquaculture equipment
Plastic pipes and tubular containers
Long industrial tanks
Playground equipment components
Floating structures and pontoons
