In addition to manufacturing rotomolded plastic products, we offer additional services such as CAD design, finishing and assembly, packaging, warehousing, quality assurance, and drop shipping.

Rotomolding is a low-pressure cast process that does not require in-mold cooling or part ejection. Our molds are usually manufactured from cast aluminum making the tooling process quick and affordable. A typical lead time for a new tooling is only 4-10 weeks depending on size and complexity and all our molds are made locally. Aluminum cast tooling also allows us to manufacture multiple duplicate molds to increase production capacity. In addition, tooling costs can be lower than alternate manufacturing methods like blow molding and injection molding.

About Blue Thumb Rotomolding Division

BlueThumb custom rotomolding is a family-owned business that has been producing high-quality custom-engineered water feature products for over 20 years.

In 2018, Blue Thumb proudly announced they were the first manufacturer in the water feature industry to invest in its own rotational molding machine. The investment allowed us to control the quality and availability of our pond filtration and fountain reservoir/basin products as well as helped us keep better control of rising costs.

Roto molding has made it easier to create our Blue Thumb basins, waterfall boxes, skimmers, and more. All of which have been environmentally tested for strength and durability.

We want to help make it easier for your business to provide quality products at a reasonable cost. We welcome the opportunity to demonstrate how rotational molding can enhance your final product, improve delivery times and contribute to your bottom line. Please contact us for prompt, friendly, and professional assistance.

Our Process

Rotational molding, also known as rotomolding, is a plastic molding process that uses rotation and gravity, rather than pressure, to mold parts and components. The molds are heated while being rotated on two perpendicular axes. This disperses the material and fills the mold. Interested?

The Blue Thumb Roto Advantage


Rotationally molded products can be as small as a ping pong ball and as large as a 20,000-gallon tank. These parts are also more uniform and have superior strength and durability when compared to other methods like blow molding, injection molding, and thermoforming.


Rotational molding allows much more flexibility in product design compared to blow molding. Complex shapes and moving sections are easier to manufacture and rotomolding offers a distinct advantage with uniform wall thickness and stress-free parts

Mold-in Graphics

Blue Thumb custom rotomolding is experienced with in-mold decorating techniques that allow detailed graphics to be permanently molded into your plastic product. Items like multi-colored logos, serial numbers, and even bar codes are seamlessly molded into the part and are significantly better quality than traditional labels.

Color Selections

Blue Thumb custom rotomolding offers color blending to match nearly any Pantone imaginable without high volume requirements. Granite, sandstone, and other special colors are also available.


Metal inserts or threaded inserts are easily added in the rotational molding process and offer a low-cost, durable, and stable way to alternative assembly techniques.

Surface Finish

From high gloss finishes to detailed textures and wood grains, rotational molding is a casting process that will duplicate any texture in the mold.
