UK shop Delta Tooling (Horsham) Ltd was approached some two years ago by prosthetics specialists RSLSteeper to assist in the manufacture of the bebionic3 prosthetic hand, which can transform the lives of amputees and help them regain independence and control in their everyday lives.

Helping out with daily tasks

The bebionic3 hand is said to utilise leading-edge technology to trigger one of 14 programmed grips and mirror human movements. Being the culmination of many years of work by RSLSteeper, the bebionic3 hand is designed so that its versatility, functionality and performance allow its users to do everyday tasks like use a computer keyboard, tie shoelaces and chop vegetables.

Operating from Billingshurst in West Sussex, Delta Tooling now produces five parts for the hand, including the aluminium knuckle, the plastic sub-section it connects to and a complex bracket that allows the opposable thumb to rotate and move backwards and forwards.

RSLSteeper originally approached Delta Tooling’s directors Gary Childs and Luke Tetlow with an all-plastic moulded product that had to be partly machined when removed from the mould tool. “The initial concept of casting or moulding the components, followed by finish machining operations before assembly and testing, gradually evolved into fully machined parts to improve quality and maintain consistency,” Childs said. “Maximising our use of Visi Machining, we developed strategies that not only machined the parts from solid billets, but produced them in highly competitive times.”
