GRP manufacturing excellence through our people, processes and standards
Our team is committed to exceeding customer expectations and providing fibreglass moulds and products of the highest quality. We pay attention to every detail in our supply chain to enhance every step of the process. Continually investing in our team, processes and standards means we add value at all stages of your journey here with MPM.
We undertake extensive pre-project work, such as precision pattern making and product development to ensure that your product is manufactured Right First Time.
Wet Lay-Up
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.
Chop Spray
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.
Resin Transfer Moulding
Here at MPM we provide a complete service from the drawing concept to designing, producing and commissioning the closed mould tooling, Resin Transfer Moulding or Closed Moulding is a cleaner and more efficient and effective way of producing a composite part. Producing a mould in this way ensures it is chemically resistant, fire retardant and extremely durable, with no risk of corrosion.

FAQS
GRP (Glass Reinforced Plastic) is a composite material made by reinforcing a plastic resin with glass fibres, resulting in a lightweight yet strong product. It’s widely used in industries such as automotive, marine, construction, and aerospace for manufacturing durable parts and structures that require high strength-to-weight ratios.
GRP components are widely used in industries such as automotive, marine, construction, aerospace, and infrastructure due to their high strength-to-weight ratio, corrosion resistance, and design flexibility. Common applications include boat hulls, vehicle body panels, building cladding, piping systems, and aerospace parts where durable, lightweight materials are essential.
Resin Transfer Moulding (RTM) is a precise composite manufacturing process where resin is injected under pressure into a closed mould containing dry fibre reinforcements. This method produces high-quality, strong, and consistent GRP parts with excellent surface finish, ideal for complex shapes and high-volume production in industries like automotive and aerospace.
Chop spray (or spray-up) is a composite manufacturing process where chopped fibreglass strands and resin are sprayed simultaneously onto a mould using specialised equipment. Compared to wet lay-up, chop spray is faster and better suited for producing large or complex shapes, but it typically results in parts with slightly lower strength and surface finish.
Wet lay-up is a traditional composite manufacturing process where dry reinforcement fibres, such as fibreglass mats or fabrics, are manually saturated with resin and then layered by hand into a mould. This cost-effective technique is commonly used for producing strong, lightweight parts in industries like marine, automotive, and construction.
