Rotational Molding is a major breakthrough in the world of plastic production. It offers many key advantages over other types of production like injection and blow molding (see below). But the bottom line for the consumer is that this process produces better, stronger plastics at lower cost.

Once a three-dimensional design of the product is drawn using AutoCad or similar computer software, a team of machinists tools a mold (usually aluminum) to the design specifications.

The mold is then sent to the plastics manufacturer, who adds the precise amount of plastic resin (hard and granular like sugar) into the mold and clamps it shut. Workers place the loaded mold into a large oven, which rotates it along both axis like a giant gyroscopic rotisserie. The aluminum heats up quickly, melting the plastic resin and coating the inside of the mold evenly. After the finished product cools and is lifted from the mold, it is inspected and shipped to the customer.

The Rotational Molding process offers several advantages over other plastic production methods:

  • Better control over plastic thickness
  • Thicker and stronger corners
  • Faster, cheaper color changes
  • Seamless construction
  • Larger and more complex pieces can be manufactured as one piece, saving assembly costs and allowing stronger construction
  • Logo/picture/text can be inserted directly into the plastic for longer wear!
  • Unlimited design options including double walls, ribbing, and textured surfaces
