The Description Of RTM Mould
Resin Transfer Molding (RTM) ------
RTM is a technology of injecting liquid resin into a closed mold. There are already stacks of dry fiber layers or preform placed in the closed mold cavity before the injection. During the injection process, resin flows and impregnating and wetting the entire surface of the perform material, when the curing cycle completes, resin become rigid plastic. After demolding, the transfer process ends, composite part is being molded.
Automotive industry has been a prominent application area for RTM molding in general for body panels, hood, fenders, and deck-lid, battery covers, A pillars, front-crash structure。
The process of Preform
So the first step of this process would be getting ready the preform or pre-cut fiberglass layer. The reinforcement comprises a variety of fiber types and forms, such as fiber tows, mats, or woven structures. In this process we need our first set of mold, which is quite simple, because it is function only to create the shape of the preform or reinforcement so we could lay them inside the second set of mold cavity.
