Internal Check supplementing
Next to a systematic incoming goods inspection, the self-inspection by the operators plays a decisive role. Every assembler has an individual inspection stamp which they use to mark the final product after completion of the assembly and inspection. Quality defects can thus be traced back to the work place. Furthermore, all products undergo an additional final check, evidenced by the date stamp on every delivered product.
The quality management system of Tünkers Maschinenbau GmbH pertaining to DIN ISO 9001 has been certified since 1996. In order to accommodate the increased requirements of the automotive industry, a changeover to the certification in compliance with VDA 6.4 of the German Association of the Automotive Industry followed in 2007, which includes QS 9000 and ISO 9001 as the new quality standard.
