Rotational molding is a cost-saving alternative to many other materials and processes:

 

Fiberglass

  • Polyethylene prices much lower than fiberglass

  • Resulting piece price much lower

  • Tooling often costs less

  • Parts are lighter

  • Design parameters are greater

  • Stress free parts

Metals

  • No corrosion

  • Part pricing usually significantly lower

  • Lighter parts

  • Lower tooling cost

  • Greater design flexibility

  • More complex shapes can be achieved

  • Rotationally molded parts are more resilient and withstand higher impacts

  • Stress free parts

Thermo forming

  • Rotational molding offers a wider selection of materials

  • More durable materials available

  • Little or no scrap and material waste

  • Faster cycle times

  • Short runs of different colors more economical

  • Hollow parts can be made without expensive secondary operations and component parts

  • Stress free parts

Injection and blow molding

  • Lower tooling costs

  • Shorter tooling lead time

  • Short to medium runs much more cost effective, yet rotational molding process can also keep up with high volume demand

  • Very large parts are economical to run

  • Much lower machine start up cost

  • Reduced manufacturing overhead

  • No material waste such as seen with sprews and runners in injection molding

  • Switching colors in production is easy and cost effective

  • Stress free parts
