Light RTM is a vacuum pressure-based closed molding process where resin is infused into a cavity with a preloaded glass mat under negative pressure.

This manufacturing method offers benefits such as short cycle times, accurate parts production, and smooth surfaces suitable for low and high production quantities.

Infusion Mat or Light RTM Mat, also known as Flow Mat, Sandwich Mat or Rovicore, is a type of fiberglass mat used in Resin Transfer Molding (RTM), Light RTM (L-RTM) and Vacuum Infusion processes.

It typically consists of three layers: two surface layers of chopped mat and a core layer of Polypropylene (PP) or resin flow layer for fast resin flow.

This type of fiberglass mat is widely used in various industries such as automotive, truck, and trailer bodies, as well as boat building. It allows for fast and efficient resin flow, which ensures a consistent and high-quality final product.
