Sometimes the best improvements start with a new material.

Gravirax needed a better snowboard rack. Together, we re-engineered their steel design for rotational molding, reducing weight, simplifying assembly, and speeding up production.

The result is a more durable, efficient solution with new branding potential. Read the case study:

Gravirax is an outdoor gear company known for manufacturing heavy-duty ski and snowboard racks that make mountain travel easier, safer, and more convenient for outdoor enthusiasts.

The Outer Edge Polar Challenge (OEPC) begins soon, pushing the limits of human endurance and wind powered engineering in one of the most extreme environments on Earth.

Gemstar is proud to support this world record attempt by providing a protective hard case designed to keep critical gear secure in real conditions, not controlled environments.

When performance matters, protection matters just as much. We are honored to play a part in helping Charles Werb and the team focus on what matters most out on the ice.

Trying to decide which manufacturing method is right for your plastic part?

Rotational molding is well suited for single-piece plastic parts with complex geometries used in rugged, high-impact applications. This process is also a good fit for parts that may require variable wall thicknesses, molded-in metal inserts, and embossed or debossed graphics.

When the application demands durability and design flexibility, choosing the right manufacturing process matters.
