What is Rotational Molding
Rotational molding (or roto molding) is a smart, cost-effective way to create strong, seamless plastic tanks. It works by heating polyethylene resin inside a rotating mold, which evenly coats the interior to form watertight, consistent walls. This process produces tanks that are durable, corrosion-resistant, and built to handle tough conditions like vibration during transport. Additionally, roto molding is faster and more affordable than traditional methods—giving you long-lasting storage without the high cost.
Roto Molding Tanks
Roto molding is a perfect manufacturing technique if you need to customize your tank. The thermoplastic process gives you unlimited options for water and chemical storage, diesel fuel storage, industrial storage, agriculture water storage, and more. Roto molded tanks are lightweight and easy to transport, are rust and corrosion resistant, and give you endless possibilities for tank size, shape and design.

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.
- We work closely with you to identify your specific tank needs; then create a detailed design prototype.
- Once the design is approved, we build a stainless steel mold to meet all of the requirements outlined during the design process.
- Our mold must meet our high quality standards before we schedule your first tank run with our state-of-the-art rotational molding machines.
- After your tank fabrication is complete, we inspect the tank for any defects or imperfections. Strict quality control measures ensure your tank meets your exact specifications, as well as adhering to our rigorous standards. The result is a high-quality, durable, custom-designed tank that meets your specific project needs. Call us today for more information about our custom roto-molding solutions.
