Rotational Molding

A hollow mold is filled with resin or polymer powder, then placed into an oven at 500-700 F. The mold rotates around two axes at less than 20 rotations per minute. Too long in the oven degrades the polymer, not enough time in the oven creates large bubbles in the item. After the product leaves the oven, it is detached and cooled.

Advantages Of Rotational Molding

  • Low tooling costs. As this is a casting process there is no pressure.
  • Consistent wall thickness.
  • Increased productivity and strength.
  • Easily create complex shapes and textures.
  • Almost no limit to product size. Several different products can be produced at the same time.
