Rotomolding cast tooling

When your design is finalized the pattern production begins. Most commonly patterns are CNC machined from the 3D model, but other options are available.

After the pattern is reviewed and signed-off on, the followers for determining the parting lines are constructed. Next, the pattern goes through the sand ramming process creating the cope and drag. Then our Tooling Department is ready to pour the tool.

 The most common type of tooling used in rotational molding that offers a wide range of surface finishes/textures. Cast Tooling is relatively inexpensive and can be made in 6 to 8 weeks depending on the complexity of the design. Learn more about Cast Tooling steps, textures, and other tooling options.

 Billet tooling is used for complex designs and when smooth surfaces are needed. Billet Tooling is usually the most expensive kind of 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, then the billet tool is ready to be framed and finished.

 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 kind of rotational mold tooling and can be made in 6 to 8 weeks depending on the complexity of the design. Fabricated Sheet Metal Tools are formed and welded. The welds are then ground and polished.

 Pouring aluminum into a sand cavity creates the tooling. Then the mold is polished and/or textured to your specification. This process takes a meticulous eye for detail. The mold cavities are then fit together. A steel frame is constructed and mounted to the casting. After the framing and fitting of the mold cavities are completed, the new tool is sent to our Rotational Molding Department to program cycle times with Rotolog technology.
