Stainless Steel Latch Slide Spring Clip for the Medical Industry

A customer in the medical industry commissioned Spring Manufacturing to provide design assistance during the design phase of a latch slide spring clip project. This part was to be used in a heart pump battery pack. We analyzed the application criteria in order to advise on material selection and to determine the ideal finishing techniques. We designed and fabricated the custom tooling for the part, utilizing standard tooling and pneumatic presses to form the specified bends while maintaining a ±0.005″ tolerance. Composed of 17-7 condition A stainless steel, the .035″ thick part was subjected to the annealing and tempering process to meet the TH 1050 hardness condition. The part was finished in a black PTFE coating.

Turnaround time for this project was 8 weeks, fabricating 1,000 to 15,000 units per order for shipping throughout the United States and Mexico. Our services were also procured for the fabrication of inspection tools for this part, in order to preserve the customer’s 100% inspection model in a cost effective manner. This part has since been passed on to an assembly house, to accommodate growing production levels.
