What is Roto Molding

Roto molding is a process where heat melts and molds plastic resin inside a hollow, closed mold. The mold is placed in the cast with temperatures ranging from 260°C – 370°C. The mold is rotated until the inside is evenly coated with the polyethylene resin. The final product created is a smooth, watertight interior and exterior. Due to the centrifugal force created during rotation, the thickness of the walls are even throughout the tank. Once the plastic cools and hardens, it can be removed from the mold. Our strong tanks withstand impact or vibration during transportation and use, and they last longer than water tanks manufactured using the injection method.

Our Roto Mold Process

We provide a collaborative and efficient process for your custom roto-molding project. Our multi-step process gives 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 create a stainless steel mold to meet all of the requirements outlined during the design process.
  3. Once our mold meets our high quality standards, 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. We ensure our strict quality control measures so 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. Call us today to learn more about our custom roto-molding solutions.

Rotational Molding Applications

Rotational molding creates sturdy, leak proof solutions for a wide variety of applications. Roto mold tanks meet requirements for water recovery and treatment, making them ideal for water containment, water storage tanks and many other liquid storage.

There is also wide range of other uses for roto-molded products because the molds are customized for specific projects.  Portable barriers, carts and carriers, corner protection, fuel cells, sporting goods, and enclosures can also be made with rotational molding. Perfect for construction, farms, cities, industry, and other applications.

Common uses are:

Rainwater Collection Fuel Storage
Wastewater Emergency
Chemical Processing Irrigation
Agriculture and Farming Composting
Construction Water Storage Recreation
Spill Containment Mining and Minerals
