Rotational molding requires less expensive tooling than other molding techniques as the process uses centrifugal force, not pressure, to fill the mold. The molds can be fabricated, CNC machined, cast, or formed from epoxy or aluminum at a lower cost and much faster than tooling for other molding processes, especially for large parts.

What Products Can Be Made from Injection Molding ...

The Injection molding process is highly repeatable and reliable for high volume production. Once the first part is produced, the second is going to be practically identical, due to the ability to make multi-cavity injection mold parts, where multiple parts are made with one cycle. Other advantages are the wide range of material selection, low labor costs, minimal …
