These suppliers must be capable of machining long and short turned parts with diameters < 1 mm on CNC and cam-controlled machines.

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.

The continuous improvement of our purchasing performance is necessary to:

  • remain a competent and strong partner of our customers
  • remain competitive in the global market
  • lower costs
  • secure quality 
  • meet deadlines and delivery schedules

Pre-requisites to becoming a supplier for INGUN:

  • high quality
  • delivery reliability
  • competitive prices
  • preliminary information in the case of production interruptions and problems
Using a supplier evaluation, your performance will regularly be evaluated by INGUN’s purchasing department. To guarantee a reliable service, INGUN needs absolutely punctual deliveries by the date stated in the purchase order acknowledgement. Should it become apparent that the supply date required cannot be met, the INGUN purchasing department must be informed immediately. The reasons which lead to the delivery delay must be investigated and remedied. In an emergency, all measures must be taken to shorten the normal delivery period.

INGUN values a partner-based, forward-thinking, and market-orientated cooperation with its suppliers, which have set their goal to satisfy our customers.
Therefore, we appreciate any suggestions or improvement measures.
