The manufacturing process

Keswick's fibreglass trays and waste bins are produced to the highest level of functionality and quality. All products are individually hand finished by highly trained and dedicated staff.

A summary of the manufacturing process

Cutting Material

The cotton furnishing material comes in on rolls. The material is cut to the required size for the tray, taking account of special requirements such as the centring of the pattern for designs such as Red Peony. A special cutting machine is used ensuring an efficient process.

Preparing for Pressing

The cotton fabric is mounted on the mould together with the glass fibre matting which has been cut to the appropriate size for the tray.

Adding the resin

A measured amount of the polyester based resin is added to the mould together a special catalyst to make it go 'off' (set) under heat and pressure. Careful pouring ensures an even surface with no holes or bare patches.


The tray is heated to 160°C (320°F) and a pressure of 40 to 50 tons applied.

Removal from the press

The resin goes off in approximately one and a half minutes and the tray is then removed from the mould using compressed air.

Cut and trim

The edge of the tray is trimmed whilst still hot and the trays are then stacked under pressure over night to ensure they will never warp once fully cured.


The edges are sanded ready to receive the edging strip.

Edging and finishing

The edging is hand applied and trimmed, using a special machine for placing the glue within the centre of the edging. The tray is then cleaned, inspected and packed.
