Low-Cost Tooling

Since rotational molding involves very low pressure, it does not require the high-strength tooling demanded by other plastic processes. No internal cores are necessary for most applications.

For our customers, this translates into a high-quality, durable mold that can be produced relatively quickly and at substantially less expense. These advantages make rotational molding ideal for low-to-medium volume runs or for trial runs for a part that may eventually be mass-produced by another process.

The standard for rotational-mold tooling is cast aluminum, due to its high durability and thermal-conductivity properties. Cast aluminum also has the benefit of being relatively easy to modify, so tool alterations can be made at much lower cost than is typical with tooling for other plastic processes. For complex applications that demand tight tolerances or for multiple-piece tools, a CNC-machined mold is a common alternative.

Since mold selection and design are critical to the success of any rotomolding project, our engineering team will be happy to help you decide which option is right for your goals and budget.
