OFPServices

Six processes, handled in house.

We are a fiberglass shop first. We also run thermoforming, injection molding, and metal fabrication, and our own mold shop supports all of it.

01Service

Custom fiberglass

We have molded fiberglass in Hohenwald since 1995. Design, tooling, and production are all handled in house.

After three decades of this work, we know the molding processes well enough to pick the right one for the part.

In-house mold shop

Every fiberglass part starts with a mold, and we build ours here. OFP keeps a full staff of skilled mold fabricators in Hohenwald, so tooling for a new product is made in the plant that will run it.

The mold shop is a big part of how we have added capacity and new products.

Open molding

Open molding is a fast way to develop a product because the process is simple and relatively low cost. We run two methods.

Hand lay-up is used for low-volume production of large parts and components. Spray-up handles more complex shapes and moves quicker: a chopper gun lays chopped glass fiber and catalyzed resin into a low-cost open mold, and the part cures at room temperature. It suits large parts such as walk-in tubs, showers, and travel trailers.

Thermoforming

Thermoforming turns plastic sheet into a finished part, and it takes less tooling investment than other molding processes. In vacuum forming, a heated sheet is stretched over the mold and vacuum pulls it tight to the surface.

We thermoform custom trays, walk-in tub doors, and travel trailer components.

Steel and aluminum fabrication

We fabricate stainless steel and aluminum, with engineering and manufacturing working together across a wide range of fabrication work.

OFP is a single source for custom steel and aluminum fabrication.

Injection molding

We mold high-quality injection parts alongside our fiberglass work.

Like everything else at OFP, the parts are made in Tennessee.

Family owned, and still molding fiberglass in Hohenwald.

We manufacture for wholesale distributors and other manufacturers. OFP does not sell direct to the public.
