RTM / LRTM Resin Transfer Molding Services

The internal surfaces of mold may be gel-coated. If required the mold can be pre-loaded with a preform. The maximum volume of the fiber content of a transfer molded composite can be 60%. The material that used for filling may be a preheated solid or a liquid. This filling material is loaded into a chamber known as the pot. A ram or plunger is used to move the material from the pot into the heated mold cavity. If feed-stock is initially solid, we apply forcing pressure and mold temperature to melt it. Besides, we make use of standard mold features such as sprue channels, a flow gate and ejector pins for the ease of molding. We use heated mold to ensure that the flow remains liquid for complete filling. Once filled, we put the mold to cool down at a controlled rate for optimal thermoset curing. With our RTM / LRTM resin transfer molding services, we use a liquid thermoset resin to saturate a fiber preform placed in a closed mold. The process that we use is versatile and can be used to fabricate products with embedded objects such as foam cores or other components in addition to the fiber preform.
