Because the “claw” had originally been designed as an end of arm tooling feature, there was some redesign necessary to create a hand-held version. The original claw was redesigned to make the handle more ergonomic. The first claw they produced was prototyped and printed on their Markforged X7 3D printer, out of Onyx. After inserting approximately one million parts and almost a year later, the eight fingers on the claw only recently needed to be replaced. The overall cycle time has been reduced by 19-20 seconds, which has increased production by 50%.
The faster cycle times allow Zero Tolerance to finish orders more quickly, gives them more of an opportunity to run other jobs in the press, cuts back on employee hours needed to run those parts, while eliminating the burn hazard. Zero Tolerance has now created three different versions of the “claw” that are used for three different moulds they run in-house and have even produced “claws” for other machine shops who have submitted purchase orders.
