Fuel Tank Made With Gemstar’s Robomold® Technology Wins 2023 ARM Product & Safety Awards

Gemstar Manufacturing was awarded the 2023 Product of the Year at the Association of Rotational Molders annual meeting in Kansas City last month. 

Cannon Falls, Minnesota – Gemstar Manufacturing earned the Association of Rotational Molders (ARM) 2023 Product of the Year award for its specialized fuel tank manufactured using Robomold® technology. The entry sample offered a cutaway to see the internal features of the tank, including an anti-spill funnel in the filler spout in order to comply with EPA guidelines.

In addition to the Product of the Year Award, Gemstar Manufacturing also received the 2023 ARM Safety Award for having an exemplary safety year. The awards were granted last month at the annual ARM conference in Kansas City. 

2023 ARM Product of the Year Award  

The innovative fuel tank was recently featured in a product Case Study, as well as Tech Note co-authored by Gemstar and its vendor partner, Celanese. The Tech Note illustrates how Gemstar’s partnership with Celanese, a global chemical leader, has allowed them to manufacture premium fuel tanks using single-layer acetal solution designed specifically for rotational molding.  

Celanese’s Hostaform® POM RF delivers unparalleled toughness and rigidity, temperature resistance, wear resistance, and low fuel permeation while Gemstar’s Robomold technology provides ideal precision repeatability necessary for highly specialized custom parts. This technology produces tighter tolerances, design flexibility, and high control that is unmatched in the industry.  

The innovative solutions provided by Gemstar and Celanese’s partnership combine high-quality and EPA/CARB compliant products unmatched by its competition. The precise process allows for optimization of material and reduction of processing time by up to 50% compared to industry average. These tanks can accommodate a nearly endless array of fuel types and the streamlined design is formulated through a single-layer solution, contrary to other options on the market.  

The product is voted on by employees of ARM Member Companies who attended the annual meeting in Kansas City.
