Rotomolded Food Grade Products
Granger Plastics Company has been rotationally molding certified prime virgin materials since the inception of the company. Because of Granger’s stance of not running any off-grade or “wide-spec” materials, coupled with Granger’s on-going pursuit of high-quality, Granger is the perfect candidate for your food application rotational molding needs! Using USDA/FDA certified prime virgin materials for food contact, Granger can successfully take your food product or food processing product from start to finish by assisting with the rotational molding design to ensure it’s moldability, build your tooling or oversee the completion of your tooling and then take it right through production! Even stock product and drop ship to your facilities around the World if that is what your operation requires!
While polyethylene is the most common material for the rotational molding process, Granger has also found that polypropylene is a great fit for a number of rotomolded food grade applications because of its enhanced abrasion resistance and its ability to withstand elevated temperatures. Granger Plastics also has partnerships with other companies who have the ability to enhance the physical properties of molded components in a secondary process which will give the products superior strength and able to withstand elevated temperatures. Some food applications require heavy wall polypropylene parts, which Granger Plastics was capable of molding at unprecedented wall thickness levels that were never previously experienced by many experts in the rotomolding industry.

Granger Plastics also touts an ability to hold tighter tolerances than most of the rotational molding industry’s accepted standards. This allows Granger to be successful in working with many companies on converting products to the rotational molding process such as stainless steel. Being able to convert a product or component from stainless steel to a polymer based product allows for substantial savings and process improvements for a growing number of customers.
With Granger Plastics offering a complete single source rotational molding supply operation, complete with in-house molds, secondary trim & assembly, packaging and drop shipping, it continues to make since why Granger Plastics Company should be your partner in rotational molding.

"Solutions Beyond Expectations"
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.

Rotational molding tolerances are influenced by much more than a number on a drawing.
Part size, geometry, shrinkage, tooling, wall thickness and cooling all affect dimensional accuracy.

Rotational molding and blow molding both make hollow plastic parts — but they solve very different manufacturing problems.
Tooling, part size, wall thickness and volume all matter.

Rotational Molding vs. Injection Molding — which process is right for your product?
The answer depends on more than just part shape. Tooling investment, production volume, part size, durability, materials, wall thickness, and long-term manufacturing economics can all influence the best choice.
We break down the strengths, limitations, and ideal applications of both processes in our latest article on RotationalMolding.com.
