The Rotomold Tooling Process

Our design and engineering team will work with you to ensure your design is perfected for rotomolding. Once your design is finalized, we’ll work together on a mold. We use fabricated, cast, or machined molds, and our team will help determine what’s best for your product.

  • In-House Mold Making – A mold using fabricated aluminum at our in-house facilities. This is a great option for products like RV liners or holding tanks. If you already have a mold that needs modifications, our team can handle that on-site in our mold building and repair shops.
  • Outsourced Molds – If your product is more complex, we will work with preferred mold makers to get you the best quality molds required for your project.
  • Mold Repairs & Modifications – Our mold shops will handle any future repairs or modifications that may be needed with your mold. If you come to us with an existing mold that requires adjustments, we can make any required modifications in-house.

Tooling Types

What are the choices for tooling? To determine which is right for your product or part, we’ll need to answer these questions: What is the size of the finished part? How complex is the geometry of the part? What kind of surface finish is required? Will you need more than one cavity?

  • Fabricated Sheet Metal Tooling – Fabricated Sheet Metal Tooling is most commonly used on large parts that don’t have complex design geometry. Sheet Metal Tooling is usually the least expensive rotational mold tooling and can be made in 4 to 6 weeks, depending on the complexity of the design. Fabricated Sheet Metal Tools are formed and welded. The welds are then ground and polished.
  • Billet Rotational Molding Tooling – Billet tooling is used for complex designs and when smooth surfaces are needed. Billet Tooling is usually the most expensive rotational mold tooling and can be made in 6 to 8 weeks, depending on the complexity of the design. The billet tooling starts with a 3D solid model of the tooling halves that are CNC machined, and then the billet tool is ready to be framed and finished.
  • Cast Rotational Molding Tooling – The most common type of tooling used in rotational molding offers a wide range of surface finishes/textures. Cast Tooling is relatively inexpensive and can be made in six-to-eight weeks, depending on the complexity of the design. Learn more about Cast Tooling steps, textures, and other tooling options.
