RTM LIGHT

RTM light is a closed mold system.
We work with a heated solid under mold (gfk) and a very thin gfk upper mold.

  • The closing of the mold and the injection are vacuum assisted.

  • After applying the gelcoat we insert the fibers and close the mold.
  • The resin we inject using an injection pump ore suck up the resin using vacuum.

  • Filling of the mold with the aid of vacuum technology.

  • Closed mold system.
  • Fiber reinforcement is placed before closing the mold.

  • All type of reinforcements are possible.

  • Inserts can be integrated.

  • Good mechanical properties, depend of type fiber reinforcements used we can go up until 35%.

Advantages of this technique

  • Upper-mold in case of lite RTM is very thin and flexible, in case of infusion the upper-mold is replaced by foil;
  • Sandwich-construction is possible;
  • More parts, until 16 parts a day/shift depending of using gelcoat or not; cooling jig is necessary;
  • Thickness accuracy up until +/-1mm;
  • Thickness of the part defined by the quantity and type of fiber layers used;
  • This technique is perfect to use for big parts, for example boat hull.
