Rotational Molding is a process for making hollow plastic parts. Typical parts include containers as well as material handling, industrial and recreational equipment. The process produces a seamless hollow piece. Small parts can weigh less than a pound. Larger parts weigh up to several hundred pounds. The wall thickness can be controlled.

Many types of plastics can be roto molded, most often polyethylene, in a wide range of colors. Linear polyethylene is our primary material due to the fact that it exhibits excellent strength, durability and toughness. All of our materials include UV inhibitors making them suitable for extended outdoor use.
