What Is Resin Transfer Molding. Resin transfer molding rtm process rtm is a vacuum assisted resin transfer process with a flexible solid counter tool for the b side surface compression. Using our resistant capacitive high pressure high temperature sensors you can ensure the preform blanks are given their required stiffness in advance of th.
This process yields increased laminate compression a high glass to resin ratio and outstanding strength to weight characteristics. The advantages of a closed mould process are considerable but include the following. A piece of uncured rubber is placed into a portion of the mold.
Light resin transfer molding or light rtm is a process by which composite products are manufactured using a closed mold system.
Resin transfer molding overview. The salient difference between vartm type processes and standard rtm is that in vartm resin is drawn into a preform through use of a vacuum rather than pumped in under pressure. Resin transfer molding rtm is a liquid injection molding process that utilizes liquid resin injection under pressure through either a stack of dry fiber layers or a dry fiber preform placed in a closed mold cavity. In rtm resin is injected under pressure into a mold cavity.
