Process: GRP Moulding


Glass-reinforced plastic (GRP), commonly referred to as fibreglass, is a material mainly used for reinforcements, coverings, insulators, structures and enclosures.

Fibreglass is a lightweight and rigid material made typically with epoxy, vinylester or polyester thermosetting plastic, as well as fibres of glass that act as a type of reinforcement.

In the manufacture of a fibreglass part, fibres of glass (usually in sheet form) are layered over a mould (called a buck or plug) in the shape of the final product and then plastic is applied to the fibres. It is possible to add more layers to increase the thickness and thus, the strength of the final product.

Fibreglass is mostly used for small series or one-off productions, within industries as diverse as marine and motorsport.

    Plastic & Rubber-GRP Moulding

    This company specialises in boat and yacht exhausts for the marine industry and is looking for a supplier to mould lift silencers which will be used with the exhaust system. Tooling is also required. There are a few sizes of these components; however, quotes are required for a basic size as shown, with scope for small size variances later. Quotes are required for 500 off per year, which will most likely be ordered in regular call offs of 100 off. Pricing and quality/accuracy to drawings is vital for this enquiry and once a supplier is found, there will be additional opportunity for increased volumes in the future.

    Plastic & Rubber-GRP Moulding

    This client, a manufacturer of bespoke optical equipment, seeks a supplier to produce the attached fiberglass planters. These are destined for an outdoor application; as such, they must be provided with a durable matte finish inside and out. The client's current supplier is unable to manufacture these items to the standard required and therefore, the buyer is keen to hear from those who are capable of undertaking this project. Suppliers able to offer competitive pricing, whilst maintaining high quality and reliable lead times, will be seen favourably.

    Plastic & Rubber-GRP Moulding

    Currently made in China, these GRP moulded handrail parts have undergone a redesign and the client is looking for a new supplier with the expertise to make these within the UK going forward. The attached solidworks drawing shows just one of the 17 items in the range, so this is a fantastic opportunity to work with a new client on a long-term basis across several products. The other items in the range will be of a similar size, but slightly different shapes to the drawing as shown in the JPEG attachment. Quotes are required for 50 off and 100 off of the handrail part depicted in the Solidworks drawing initially; however, once the supplier has been chosen, this will lead to orders of all of the other parts in addition, when the client is ready to place an order.

    Plastic & Rubber-GRP Moulding

    This start-up company is currently seeking a supplier who can manufacture the attached hyperloop pod fibreglass shell. The buyer has an order ready to place for its production and is open to suggestions for the overall thickness and sizing of the shell. Those that are interested in being considered for this job are asked to make contact with the buyer directly to discuss. The ideal supplier will be able to produce these parts economically and provide a high-quality end product. Delivery on time is also important for this request. Once a relationship has been established, further projects could be made available in addition to this initial requirement.

    Plastic & Rubber-GRP Moulding

    This jukebox manufacturer - whose subcontracting needs total in excess of £86,000 a year - is looking to work with a supplier who can produce a moulding that is both antistatic and impact-resistant. This will be used to protect a wall-mounted design weighing between 25kg to 30kg. There will be an ongoing need for this design, making this a great opportunity for suppliers who aim to increase their customer base and fill long-term capacity.
