Rotational Molding - PlasticRotational

In the rotational molding process, a hot mold is filled with a small amount of plastic powder and rotated in every direction.

The plastic melts onto the inside of the mold and forms a hollow part.

Rotationally molded parts are usually very strong and can be made in large sizes with relatively inexpensive tools.

However, the process can be slow, and is mostly used when a small or medium number of parts are needed.
