About Rotational Molding

Rotational plastic molding is an extremely versatile and economic process that relies on gravity and heat to produce parts of unequalled strength.

Steps in Rotational Molding Process:

1. A pre-measured amount of plastic resin is placed into a mold.
2. The mold is then moved into an oven where it is rotated on two axis. As the resin melts, it coats the inside surface of the mold cavity, allowing for excellent uniform wall thickness.
3. Once the resin is completely fused, the mold is removed from the oven and cooled by air or water.
4. Then the part is removed from the mold.

The finished result is a stress-free, light weight, and seamless design that is very durable.

There are a variety of plastic resins available to the rotational molding industry. Our knowledgeable staff in our Nashville, TN office will help determine which resin will perform best for your application. We will also help in the design stage of product development to ensure that the finished product meets your requirements and is within our process capabilities.

The flexibility of our process allows for a wide range of shapes and sizes to be manufactured. We are also able to offer products in a wide range of colors, with graphics molded directly into the part.

The cost of tooling is one of the biggest advantages of rotational molding.  The cost of having a mold built is significantly less than most other plastics processes.  Molds can be machined, cast, or fabricated from materials like stainless steel or aluminum.  Cast and machined molds are best when exacting tolerances, or cosmetic finish are important to the finished product.  Cast molds offer a wide range of finishes from wood grain to a mirror finish.  Fabricated molds are more economical than cast or machined but offer less options for finish.
