Tooling

Tooling for rotational molding is often less expensive than other plastic processes, though it is a necessary upfront cost of manufacturing. A tool for roto-molding is usually either cast or fabricated out of aluminum or steel. They are often multi-part tools and can sometimes be created to manufacture more than one part at a time.

The quality of the parts that are manufactured is directly related to the quality of the tooling they are being manufactured from. So, having an engineer who understands roto-molding design as well as utilizing a metals shop that produces high quality molds is of great benefit to the manufacturer. Proper tooling on the front end can alleviate problems on the back end of manufacturing.

From time to time molds will need to be maintained or repaired. Utilizing a rotomolder with an in-house metals shop can reduce downtime of this dramatically. An in-house mold shop also saves shipping dollars for the essential care and repair that is going to need to be done. When a mold shop is able to make necessary maintenance quickly it allows the mold to be put back into the production schedule as quickly as possible. Because maintenance can often be required without previous notice this could keep the product supply chain moving during a time of increased need.
