Wet Lay-Up Wet Lay-Up workflow Mpm team applying several layers of resin

With over 45 years of experience in the production of GRP moulds, this technique has been with us since our early days.

Manufactured by an exceptional team here at MPM by applying several layers of resin until the desired amount of glass fibre is achieved. 

Our quality standards and attention to even the smallest details ensure that we match the customer demands and product requirements. Our after-sales service is arguably the best in the sector and we pride ourselves on our Right First Time (RFT) targets.

With no size limitation, this technique is more often used to produce larger moulds such as water treatment tanks, shower pods, caravan parts and commercial vehicle parts.

Our experience here has grown over the years and we now have several trained operatives and dedicated booths to offer a speedy and exacting quality of service in this area.
