The initial sample under series-production conditions

The last step in the product development of your stamped parts before the start of production is the manufacture, inspection and approval of the first sample produced under series-production conditions.

The official Production Part Approval Process (PPAP) during the certified quality-management process concludes the development of your part. The PPAP documentation confirms that ERNST can carry out the series production according to your specification. The initial samples are the binding proof of this.
