"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.
Read the latest article at **RotationalMolding DOT com**.

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.

Draft angles matter.
Better part release. Less tooling wear. Fewer production headaches.
Another small design detail that can make a BIG difference in rotational molding.

Good rotomolded parts don’t just need the right material and wall thickness — they need to come out of the mold cleanly. 👀
Draft angles can have a major impact on part release, tooling wear, surface quality and production efficiency.
Too little draft can turn a good design into a manufacturing headache.
We just broke down how draft, mold texture, geometry and polyethylene shrinkage all work together in rotational molding.
🔥 Better design starts before the mold is ever built.

🔥 **SMALL COMPONENTS. BIG ENGINEERING DECISIONS.** 🔥
🔩 Molded-In Threaded Inserts vs. Spin-Weld Fittings ⚙️
When it comes to rotational molding, the smallest design details can have a HUGE impact on product performance.
💪 Strength & Durability
💧 Sealing & Leak Resistance
🔧 Mechanical Connections
⚙️ Design Flexibility
💰 Manufacturing Costs
Two different methods. Two different sets of advantages.
**The right choice isn`t always obvious. That`s where experience and engineering expertise make the difference.**
At The Granger Plastics Company, we know that successful rotomolding starts long before the mold enters the oven.
🚀 **DON`T JUST MOLD IT. ENGINEER IT.**

Not every large plastic part should be rotomolded.
And not every large plastic part should be thermoformed.
The wrong manufacturing process can cost you in tooling, durability, wall consistency, production efficiency, and product performance.
The right process starts with the part.
Hollow or open?
Seamless or sheet-formed?
Low volume or high volume?
Simple geometry or complex geometry?
That’s where the real decision gets made.
Rotational molding and thermoforming both have their place — but choosing the wrong one can get expensive fast.

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.
