Resin Transfer Moulding (RTM)


In High Temperature RTM our unique technology helps to develop an optimal manufacturing process, to monitor the process in real-time, prevent manufacturing flaws and expensive cfrp scrap.

High Temp RTM (normally over 150oC) is used for the production of high quality structural parts most of the times using a monocomponent resin. Our in-mould sensors can be used at temperatures up to 210oC and up to 60 bars injection pressure and have limited sensitivity to carbon fibres. The use of our systems can:

  • ensure good filling with repeatable patterns
  • monitoring resin's viscosity during injection
  • optimise curing especially to avoid large exotherms
  • identify end-of-cure
  • take advantage of near to "end-of-life" resins
  • monitor production for quality control purposes

 

Optimold for cure monitoring can be combined with Optiflow for monitoring when resin arrives at specific locations into the cavity or at the outlet gates so automatic control actions can be executed accordingly. All these data can be recorded and a detailed track of the manufacturing quality and performance is available to the manufacturer.

Our systems do not require any special treatment, release agent or cleaning besides the normal maintenance of the tools. To minimise the burden at the production floor wireless communication can be used.
