This technique utilises a top- and bottom mould that are closed onto each other under pressure. Inside of the mould (which can be produced by our in-house mould workshop) a gelcoat is typically applied for surface quality purposes, followed by a glass package. Subsequently, the resin and the hardener are added and the mould is closed under pressure.

Shape and volume of the product is hereby determined by the space between the two moulds. The pressure forces the resin into all open corners. Shortly after the moulds can be depressurised and the product can be dislodged.

This production method is mainly recommended for larger qualities. The products are dimensionally particularly stable and have a high surface quality. Tanks, vehicle body parts and construction elements are some examples in which this processing method is used.
