High Quality

Our finished products will not bulge, distort, or discolor. They are resistant to chemicals and corrosion and stand up to the test of time.

Cost Effective

Economic tooling costs, design flexibility, and quick turnaround are some of the reasons why rotational molding is cost effective. The parts are made locally, in Michigan, which offers quick shipping to the mid-west.


Rotomolded parts offer relatively stress free corners, uniform wall thickness, and one-piece lightweight construction.

Shorter Lead Times

Whether you are working on a proto-type or a full scale production, count on Three60 Roto to deliver when you need it.

Linear Low Density Polyethylene (LLDPE)

Because of its physical properties, Three60 Roto most commonly uses LLDPE. This material is durable, with a high tensile strength. It offers flexibility in design and is simple to match or change colors.

Cross-Linked Polyethylene (XLPE)

Rotational molded parts made from XLPE have improved Environmental Stress Crack Resistance (ESCR), a characteristic that is beneficial in outdoor and industrial applications. These products have a high resistance impact, ductile strength, low cost and sustainability in cold temperatures.

High Density Polyethylene (HDPE)

HDPE also has high tensile strength, but offers a lightweight characteristic, and is compliant with USDA and FDA guidelines. It is also suitable for large products and complex designs.


Nylon parts are extremely wear and heat resistance. Nylon has other key characteristics such as abrasion, durability and high impact, making it an excellent choice for many automotive, industrial, recreational, and lawn and garden applications.
