Idea

32 years isn’t something you stumble into.

It comes from solving difficult problems. Designing better parts. Building better tooling. Learning from decades of production experience — and continuing to invest in what comes next.

Since 1994, The Granger Plastics Company has helped turn ideas, engineering challenges and demanding applications into rotationally molded products built for the real world.

We’re proud of 32 years in business.

But what excites us more is the next project.

If your company has a product that’s too large, too complex, too corrosion-prone, too difficult to manufacture — or simply needs a better way to be made — we’d like to hear about it.

How much does rotational molding really cost?

The answer depends on more than just the price of plastic. Tooling, part size, geometry, material selection, production volume, finishing requirements, and secondary operations can all affect the final cost of a rotationally molded product.

We put together a practical guide explaining the major factors that influence rotational molding costs—and what companies should consider when evaluating a new project.
