Custom Rotational Molding.
Seamless, stress-free hollow parts — multi-station machines with 42 total arms and CNC secondary trimming for tanks, housings, and large durable components.
Seamless, hollow, durable.
Rotational molding rotates a heated mold on two axes so resin coats the walls evenly. The result is a seamless, stress-free hollow part with uniform walls and no weld lines.
It's ideal for large, durable, hollow parts — tanks, containers, and housings — at low-to-medium volumes with moderate tooling cost.
- Seamless hollow parts. Uniform walls, no seams or weld lines.
- Multi-station capacity. 42 total arms across machines.
- CNC secondary trim. Clean cutouts and finishing.
- Tough by design. Durable polyethylene parts.
