Usually, the mould is formed from aluminum or steel, but sometimes composite molds are used. The two sides fit together to make a mould cavity. The distinctive feature of resin transfer moulding is that the reinforcement materials are placed into this cavity, and before the introduction of the matrix material, the mould set is closed.
Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold. Transfer molding is different from compression molding in that the mold is enclosed [ 1 ] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact. [ 2 ]
What sets SQRTM apart from standard resin transfer molding is the substitution of a prepreg layup rather than a dry fiber preform. [3] SQRTM is an RTM process adapted to prepreg technology. The prepreg is placed in a closed mold and during the cure cycle, a small amount of resin is injected into the cavity through ports positioned around the part.
Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.

Similar to the methods performed in resin transfer molding, Light RTM involves a closed mold process. A vacuum holds mold A and mold B together to result in two finished sides with fixed thickness levels. Vacuum rings around the tools hold the molds together for this process after dry fiber reinforcements are loaded into mold A before joining ...

It can be referred to as casting for certain geometries and material combinations. It can be referred to as a profile for certain continuous processes. Some of the processes are autoclave moulding, [63] vacuum bag moulding, [64] pressure bag moulding, [65] resin transfer moulding, [66] and light resin transfer moulding. [67]
