Rotomolding of Plastics
Rotational Molding, also commonly known as rotomolding, rotational casting and even roto-casting is a plastics manufacturing process for producing incredibly durable products with a nearly limitless lifespan. A variety of materials are available for rotomolding, with grades of polyethylene (PE) being the most commonly molded material.
The rotomolding process requires a mold or a tool, which can be produced by a number of methods including fabrication, casting or machining. Molds for the plastics manufacturing process are typically made from Aluminum, while some tools are fabricated from Stainless Steel or Carbon Steel. Many in the field of rotational molding prefer to see molds for rotomolding built from aluminum as it wears better when exposed to water in cooling cycles of the rotational molding process better than carbon steel, which typically rusts, providing the opportunity to transfer rust onto the molded products. Aluminum also is typically easier to modify and maintain in comparison carbon steel molds as well.

The rotational molding process is a specialized and unique plastics molding process, used to create hollow, polymer based products and components for a never ending plethora of applications. Roto-molded products are extremely durable and typically have a very long service life. While many materials are commonly used for the roto process, polyethylene (PE) is the most common. The rotomolding production process requires a mold for rotational molding to produce the product or component. It is critical to work with someone who is experienced in rotomolding design and knowledgeable in molds for the rotomoulding process, in effort to keep costs minimized, project kick-offs on time and quality products being manufactured. Design for rotomolding is an essential part of any rotational molding project. It is imperative to address all desired features and functions of the product or component during the design stage, in effort to incorporate necessary features into the molds and ensure that the product is capable of being produced and successfully removed from the tooling.
