High-precision turned parts:
We are looking for specialists for high-precision micro turned parts, who “start where others stop”. These suppliers must be capable of machining long and short turned parts with diameters < 1 mm on CNC and cam-controlled machines. The complete processing such as e.g. applying of cross-holes or milling work all within one setting should be your day-to-day business, and not pose a big challenge for you. Proficiency in re-work processes such as de-burring or hardening of parts is also a must. You must be able to machine steel, brass and beryllium copper. Your batch sizes start at 100 pieces. 

High-precision deep-drawn parts:
Deep-drawn parts with highest precision and small tolerances.

We want to show all our present and future suppliers the easy way to a close, trustworthy, fair and partner-like cooperation. A decisive aspect in the cooperation is a high level of flexibility, consistent product quality and adherence to supply schedules. Our customers increasingly demand faster lead times and improved adjustment to the market conditions. We can only achieve this with your complete support.

Should it become apparent that the supply date required cannot be met, the INGUN purchasing department must be informed immediately.
