Rotomolding Resources for Designers

Flexibility

Rotational molding is a manufacturing process that yields hollow plastic parts with a huge flexibility in design geometry. Because it's a low-pressure process, it allows even wall thickness from 4/1000 to 1 1/2 inches.

Low Tooling Costs

Low tooling costs make smaller production runs more reasonable than with other manufacturing processes. The process also allows for relatively short product development lead times. 

Variable Sizes

Rotomolded products range in size from intricate medical masks to kayaks to massive water tanks.
