Composite industry: RTM injection


RTM process composite material infusion: applied to RTM process development and material research, mass production of composite products.


Scope of application: epoxy resin, PU polyurethane, silicone rubber, glass fiber, carbon fiber, etc.


RTM process properties.
①Less material waste
②Faster gel and cure time
③Consistent part size and thickness
④Consistent material usage
⑤Smooth surface on both sides
⑥Less VOC evaporation
⑦Higher glass fiber content for lighter weight parts
