Quality management

Quality with method

Quality management is a top priority at prukon. Our products, processes and services are subject to a continuous improvement process. This saves resources, discovers synergies and reduces costs.

With the help of powerful SPC software, we analyze, evaluate and control machine capability (cm/cmk) and process capability (pp/ppk, cp/cpk).

Other methods:
  • Feasibility analysis / feasibility assessment
  • Plausibility check
  • Initial sample test report according to VDA 6.1
  • Fault detection via SPC
  • Error evaluation according to Pareto
  • Error analysis according to Ishikawa incl. Action plan
  • Measuring equipment management
  • Workplace design according to REFA

Advance quality planning

Zero-defect strategy

We keep an eye on the entire production process even before the order is placed. We work closely with our customers and suppliers and discuss every detail relating to the manufacture of the product.

Our striving for quality also accompanies the rest of the project through to the delivery of your parts.

We use CIP/kaizen methods throughout the entire production process. By constantly proceeding according to the PDCA scheme, we live the continuous improvement process with the goal of zero-defect production.

PLP – Production Control Plan

Quality assurance measures fully documented

We use the production control plan to effectively control the quality of the end products.

It contains all quality-relevant product features resulting from customer-specific requirements and derived from FMEAs, such as test procedures to be applied, test tools to be used, test frequency, tolerances to be complied with, etc. countermeasures to be initiated in the event of dimensional deviations as well as requirements for incoming and outgoing goods inspections.

A conscientiously drawn up production control plan is the starting point for high-quality products.

Process flow chart

To master the process, you have to understand it

A process flow chart provides a logical, graphical representation of a process flow. The functional relationship and the chronological sequence of processes and sub-processes are clearly illustrated.

We use flow charts to gain a deep understanding of the relevant processes and sub-processes involved. This is an important basis for creating effective process FMEAs.

Error analysis according to Ishikawa

Effective root cause analysis in teamwork

We use the Ishikawa diagram for targeted root cause identification and fault analysis. The collection of possible causes in the team and their graphical representation make it much easier to narrow down any errors and problem areas and enable the main cause of an error to be identified.

Thanks to the group dynamic, we get quick results and can react quickly. Process sequences are optimized and the amount of rework is minimized.

As a customer, you benefit from increased process reliability and reduced manufacturing costs.
