Hand Laid Glass Reinforced Polyester (also known as GRP and FRP) is still one of the most cost effective methods of manufacturing your composite or fibre glass mouldings, especially where low to medium volume and long term production are applicable.

It has been the preferred method of production for many of our customers and we’ve been producing GRP mouldings in this way since inception nearly 30 years ago.

This method is generally limited to the manufacture of fibreglass mouldings with relatively simple shapes that require only one face to have a smooth appearance (the other face being rough from the moulding operation).

Norco GRP however are specialist GRP Manufacturers of double finished surfaces and split GRP mouldings so if your part has 5 or 6 split sections for mould release necessity or is a complex form and shape we can offer our many years of experience, knowledge and practical approach to produce your product utlising this cost effective production method.

Hand lay-up moulding may be used for the production of GRP parts of any dimensions. It is also recommended for small and medium volumes, for which the investment in moulds and equipment are not very high. Norco are GRP Manufacturers of GRP Mouldings and Composite Structures.

The contact moulding GRP method consists of applying successively into a mould:

• A release agent
• A gelcoat
• A layer of liquid thermosetting resin
• A layer of reinforcement (glass, aramid, carbon, etc.).

Contact us to see how we can help with your GRP or Composite requirements.

The reinforcement can be in the form of chopped strand mat, woven roving or multi axial stitched fabrics. This is then impregnated by hand with the aid of a roller or a brush. This operation is repeated as many times as there are layers of reinforcement, in order to obtain the desired thickness of the fibreglass mouldings.

Laminates are left to cure under standard atmospheric conditions. The main advantages of the finished Composite Construction are:

• Readily available materials.
• Low cost tooling, if room-temperature cure resins are used.
• Wide choice of suppliers and material types.
• Higher fibre contents and longer fibres than with spray lay-up.
