What is Roto Molding?

The process of roto molding starts when heat melts plastic resin inside a hollow, closed mold. The mold is placed in the cast with temperatures ranging from 260°C – 370°C. As the mold is rotated, the inside is evenly coated with the polyethylene resin. A smooth, watertight product is created with  walls which have even thickness due to the centrifugal force created during the rotation. Once the plastic cools and hardens, it is removed from the mold. This strong roto molded tank can withstand impact or vibration during transportation, and is made to last longer than other water tanks manufactured using the injection method.

Our Roto Mold Process

We are dedicated to providing a collaborative and efficient process for your custom roto-molding project. We have a multi-step process, giving careful attention to detail and precision.

  1. We work closely with you to identify your specific tank needs; then create a detailed design prototype.
  2. Once the design is approved, we build a stainless steel mold to meet all of the requirements outlined during the design process.
  3. Our mold must meet our high-quality standards before we schedule the project run on one of our state-of-the-art rotational molding machines.
  4. After the tank fabrication is complete, we inspect the tank for any defects or imperfections. Our strict quality control measures ensure that your tank meets your exact specifications and adheres to our rigorous standards. The end result is a high-quality, durable, custom-designed tank that meets your specific project needs.
