Our Range

Full RTM

Resin Transfer Moulding (RTM) is a closed-mould process for manufacturing high performance composite components in medium volumes. In RTM, reinforcments are positioned in a mould and then the resin, which can be Fire Retardant, DCPD, Orthophthalic or Isophthalic can be injected through a vacuum or pressure.
RTM parts are typically smaller than traditional Hand Lay Up and Spray up, but it offers a significant reduction in styrene emissions. RTM also allows better positioning which can result in the more strength and stiffness at critical spots to obtain high fibre loading and higher mechnical properties as a result.

Light RTM

Light RTM offers more flexibility in the types of resin and fillers that are possible and a range of different fibre contents.
The benefits of LRTM are better cosmetic finishes, faster cycle times and and less variation in part thickness, compared to hand lay and spray-up techniques. LRTM is recommended for products with high-strength to weight requirements or moulds that could cause die-locks on rigid mould surfaces.

Silicone Membrane

Silicone membrane offers a more sustainable and environmentally friendly alternative to Nylon bagging. Silicone membrane can offer an improved component finish when compared to hand lay or spray-up and can be completed without long training courses.
