Fiberglass Molding Services

Listing ID #4677183

Every fiberglass molding operation starts with the usage of an object that is called a buck or a plug, made using a certain type of foam. This buck is nothing but a replica of the final object that would be made after the fiberglass molding. Once we have made the plug, our experts spray it with a mold release agent, a typical kind of wax, and/or PVA (Polyvinyl alcohol, to ensure that the final object is easily separated post the completion of the molding process. After putting this mold release agent, we use a roller, brush, or a spray gun to apply a gel coat on the plug. This gel coating is usually a kind of pigmented resin to give a durable and harder finish to the mold’s surface. After we have successfully applied both the mold release agent and the gel coat, we cover the plug’s surface with different layers of resin and fiberglass. In this process, we make use of a fiberglass that resembles the final product in mind.
The next step is called the laying-up process. In this step, we add a layer of fiberglass mat on the surface, over which, we apply a layer of resin. To ensure there are no air bubbles on the surface, we use a special kind of roller to remove any bubbles that might have been left while curing the resin. If air bubbles are not removed, it might reduce the strength of the final finished mold. Once this is done, we move on to the fiberglass spray lay-up process. This process is also very beneficial in producing molds as it is very effective in filling up the cavities and corners where the weave or glass mat might have proven to be stiff to reach. Once all this is done and we have covered the mold with the final layer of fiberglass, we let it rest for some time to ensure the resin is cured and properly set up. Lastly, we take separate the plug from the mold using special wedges. For this separation, we might also incorporate various advanced techniques like resin transfer molding.
