What Is the Rotational Molding Process?

Rotational plastic molding is a specialized process used to create tough, high-quality tanks that can handle demanding jobs, especially in construction. Unlike traditional methods that rely on pressure, this process uses heat and rotation to evenly shape and strengthen the tank material. The result? A tank that’s built to last.

How Does It Work?

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. 1. Heating and Melting: Plastic resin is added to a hollow, closed mold, which is heated to temperatures between 260°C and 370°C.
  2. 2. Rotating the Mold: The mold rotates inside the oven, evenly spreading the melted resin across its interior.
  3. 3. Smooth, Watertight Finish: The rotation ensures an even wall thickness, creating a smooth, watertight surface both inside and out.
  4. 4. Cooling and Hardening: Once cooled, the plastic solidifies into a strong, impact-resistant tank.

Our Roto Mold Production Process

We take pride in a precise and efficient roto-molding process designed to deliver custom tanks that meet your specific needs. Every step is carefully executed to ensure durability and quality.


Steps of the Process:

  • Heating the resin to the correct temperature.
  • Rotating the mold for even distribution.
  • Cooling to form a strong, seamless tank.

Why Choose Rotational Molding for Your Tanks?

  • Even Thickness: Rotation ensures the walls are consistently strong and durable.
  • Built Tough: Withstands impact, vibration, and rough environments—perfect for construction jobs.
  • Long-Lasting: Outlasts tanks made using traditional methods, offering excellent value over time.

Applications for Roto Mold Tanks

Roto mold tanks are built tough and designed to handle a wide range of jobs. Using the rotational molding process, these tanks are strong, leak-proof, and reliable for storing and managing water and other liquids.
