With wet pressing the glass fibres are laid in a mould and saturated with fluid resin. The mould is usually heated up to optimise the process before sealing with a hydraulic press. When hardened, the mould is opened and the product ejected.
EM Fibreglass’s use of wet pressing includes the manufacture of meter boxes. The process is also used for equipment for the healthcare sector.
This process is used for relatively large batches. In terms of process equipment, it is a comparatively expensive investment.
The benefits of wet pressing:
- Short process time
- Even quality
