Long Fiber Injection (LFI) of a Fiberglass Cab Roof for the Agricultural Industry

Romeo RIM, Inc. helped design and manufacture a fiberglass cab roof, displayed above, for a well-known, global agricultural manufacturer. This cab roof was intended for use as a component within a piece of farming equipment. To begin this project, we worked directly with our customer to aid in the development of this part. Using epoxy molds, we created a series of fit-up and testing prototypes of the design sample. The cab roof was designed as a two-piece construction, measuring 7' x 8', with a set weight of less than 50 lbs.

Once the design concept for the cab roof was approved by our client, we then performed long fiber injection (LFI) to mold this part. Our 12' x 12' double shuttle system - the largest LFI press in the world -distributes material robotically via an open pour system. This advanced system enables the formation of larger parts that are structurally sound. We additionally carried out in-mold painting for added durability.

The cab roof incorporated certain "B-side" details, such as bosses and ribs, to further increase the strength of the material where needed. These added features also provided attachment points for secondary components.

Our LFI process allowed us to create a large, fiberglass cab roof using light-weight material, while still preserving necessary structural integrity for the servicing needs of the cab itself. This innovative molding technique provided our clients with a low-cost product, while maintaining minimal wall thickness requirements, a lower part weight, and a Class A finish. Satisfying all customer specifications for design, quality, and performance, we currently continue to produce cab roofs for this high-profile agricultural manufacturer, shipping all completed parts to various locations in North America, South America, and Europe.
