GRP Moulded Products

However, GRP moulded products require some sort of former or tool from which it is moulded. GRP in its simplest and most common form, known as hand-lay, the mould is first prepared with a release wax, similar to car polish. The colour is then applied by brush or spray to the mould face as a gel coat, which is a thickened, coloured resin. This is allowed to cure for about 20-30 minutes and is followed by layers of glass fibre matt together with the resin. This can be put down or layed-up by brush (Hand Lay), or even spray up using special machines which chop continuous filaments of glass fibre into specified lengths and blow these down in a spray of resin. The product is then formed by the hardening of the resin and glass matrix into an integrated moulding. This intern will provide the finished Fibreglass Moulding.

Over the years new technologies have allowed much more sophisticated systems to offer far greater properties. GRP Closed moulds now offer good-both-sides mouldings, and the use of core materials between the glass fibre laminations has added immeasurably to strength and durability. GRP techniques using translucent laminates can now encapsulate graphics within the laminate both for protection and for backlit displays. Special masking techniques make multi-coloured and multi-textured moulding possible. Various techniques used are RTM, closed moulds, hand lay are to name but a few.

Thus GRP Moulded products or GRP Mouldings can adapt to any industry whether it’s the construction to the rail industry. Fibreglass Mouldings (GRP) are one of the most adaptable manufacturing products available and can achieve various standards, making Glass Reinforced Plastics (GRP) one of the most versatile products on the market.
