Wall thickness plays a major role in rotational molding performance — but there’s a lot more to it than simply specifying a number on a drawing.
We just published a new technical article covering nominal wall thickness, minimum wall requirements, geometry, material distribution and heavy-wall applications.

Rotational molding defects usually aren’t caused by just one thing.
Warpage, porosity, uneven wall thickness, poor fusion and insert-related issues can all come from the interaction between tooling, resin, heat, rotation, cooling and part design.
We put together a practical guide covering some of the most common rotational molding defects — and what typically causes them.

“I wish I found them first.” — Stephen J. Sabo Jr., founder of SG Burial Platform
Damaged molds. Declining product quality. A recommendation to replace the tooling.
Steve brought the problem to Granger Plastics—and we got to work.
Months of mold restoration led to better, more consistent burial platforms and urn pedestals, and a new manufacturing relationship.
Have a product you believe in—and manufacturing problems holding it back? Let’s talk.
