Micro battery contact
This miniaturized battery contact is used in wireless, rechargeable hearing devices. Top component reliability, performance, and durability form the basis of the quality of the medical device as a whole. Our single-stage production line is at the limits of feasibility due to extremely small geometries combined with high forces. In the tool, a rivet made of titanium-aluminum alloy is fed to the stamped, bent base component, positioned with µ precision, and then caulked.
A combination of deep-drawing and micro-stamping processes are used in the production process for this stamped part, which is installed in AdBlue dosing systems in SCR systems. These processes are supplemented by in-line laser welding. A pre-etched filter runs parallel to another stamped strip in the tool. The filter and the cover are pre-stamped as part of a single-stage process. They are precisely brought into position and then welded into a solid unit using two laser points. We also achieve top precision during these delicate production steps.
Spray hole disc
The stamped part is produced as a result of combining three technologies in the progressive tool: deep-drawing and embossing processes as well as complex micro-stamping processes. This is a special production process at the limits of technical feasibility, as precise production of the diagonally stamped injection holes requires maximum resilience with minimal tool dimensions. We can adhere to extremely tight tolerances thanks to our technological expertise in high-performance tool making and our particular production expertise.
