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 do wear down from use, but they can last for many years and can be used to make hundereds of parts.
DAK Plastics is very experienced in composite tooling for when new molds are needed or existing molds need re-designed. We store all molds inside our warehouse facilities to keep them protected, and clean and wax them regularly to get the most possible use from them. Molds can be made for both open and closed-molding processes.
A very common form of fiberglass manufacturing is by open mold, spray gun applications. Hand held 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-layed, 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 the thickness of the 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. These combined assure consistency of your finished products.
The open mold process generates hazardous air pollutants and other emissions that the EPA and the State regulate. DAK Plastics maintains its compliance with these regulatory agencies and others, and continuously work to improve our methods of efficiency.
