Case Studies

Buddieguard

A finger protection device for hairdressers. Conceived by a professional hairdresser, who realised the great potential for a product that would prevent constant cutting of fingers when using scissors. The Concept has won the designers several awards for innovation.

Cotsworld Plastics involvement came when we were asked to encapsulate two cone shaped meshes to produce a two fingered protector.

Through Tool and Material trials, Cotsworld Plastics were able to establish the most suitable materials for this product.

A TPE material was finally selected along with specific additives to give the plastic a slippery surface, to prevent the plastic pulling the hair during cutting.

This product is now available in three sizes and a wide range of colours. It has been enthusiastically accepted in the market place.

Leadframe Mounted Ceramic Chip Housing

A customer had a custom requirement for a PCB mounted housing for a ceramic integrated circuit.

Cotsworlds' designers looked at the project and designed the tool to be able to mould the housing around the Leadframe legs, providing solder legs outside the housing and contact points for the chip inside the housing.

This meant that the tooling would have to be of the highest quality and accuracy, as the lead frames we only 0.3mm wide, so they could easily be bent or damaged by any slight misalignment in the tool. Cotsworlds' close working relationship with the toolmakers of the highest calibre, enabled a tool to be produced capable of moulding five housings at a time on a leadframe strip.

The added complication was that the parts had to be moulded in LCP material, which has proven problematic to many other companies.

Because of our long experience with this material and our relationship with the material manufacturer, we were able to manufacture the product very successfully.
