Fiberglass molds are made from composites tooling materials and are used to make multiple copies of a part which may or may not have a complex design. Over time, fiberglass molds wear down from use, but can last for many years and be used to make hundreds of parts.
DAK Plastics is very experienced in composite tooling needed for new molds redesign of existing molds. We store and protect all molds inside our warehouse facilities, cleaning and waxing regularly to get greatest possible use from them. Molds can be made for both open-molding and closed-molding processes.
A very common form of fiberglass manufacturing is by open-mold, spray gun applications. Handheld spray guns are used to apply composites resin and gel coat materials to the open mold. Gel coat is applied first, then a resin, catalyst and glass mixture. Materials, such as mat, foam, wood or metal may be hand-laid, and hand-held rollers are used to remove air. Once cured, the product is pulled, trimmed, and final finished.
Specifications are determined by you, our customer. This includes the type(s) of composites materials to be used and thickness of applications. DAK Plastics utilizes TFM Machines and trains all sprayers in Controlled Spray Applications. TFM Machines monitor the amount of resin and glass material applied in pounds and ounces; Controlled Spray Applications is an applied work practice to teach all gel coat and fiberglass sprayers material application methods. Combined, these assure consistency of your finished products.
The open-mold process generates hazardous air pollutants and other emissions regulated by the EPA and State of Kansas. DAK Plastics rigorously maintains compliance with these and other regulatory agencies while continuously working to improve our production efficiencies.
