In this process, the reinforcing material is first placed in the mold. In a further step, the mold is closed with a counter mold. Liquid resin is then injected into the closed mold under pressure.
Products made by RTM process have very high surface quality on both sides. The components have a homogeneous, smooth high-density structure and the best possible mechanical properties. The surface can be further improved by applying a gelcoat into the mold.
ACCENTFORM manufactures special products made of glass-fiber reinforced plastic (GRP) for industrial customers and wholesale customers in the automotive sector: from spare parts for car bodies to complex body tuning parts or trim for commercial vehicles to complete body series.
The RTM process offers the advantage of a finely structured breakdown of the work content thanks to its production structure. This makes it possible to train employees quickly and safely in the individual production steps. This ensures a reliable production process and high flexibility in the output quantity.
After the trimming necessary for the process – which at ACCENTFORM is carried out by a robot – reinforcing and adaptation parts are bonded to the body parts on the inside. To ensure a permanent and secure adhesive bond, the KTL-coated metal parts bonded by means of a 2K MMA adhesive.
The GRP surfaces up to a size of 2,0 x 3.5m can be produced in quantities of over 250 units per year using the conventional RTM process. The photo gallery and our video provide a good overview of the individual production steps from cutting the glass fiber mat, through RTM injection and assembly of the components, to delivery of the GRP cladding.
