Quality Control starts with our selection of the foundry that is most suitable for your business and continues through first samples that are accompanied by a process capability report with CpK index included. All of our foundries are ISO certified. We monitor production on-site during the casting process and ensure that final inspection quality control reports accompany each shipment. When manufacturing overseas, it’s crucial to catch any problems before production ships. If a problem somehow gets through, Brukar will ensure that the part in question is repaired or replaced. When Brukar produces samples of a new part for a customer, we make a 30 piece pilot run to prove that our manufacturing process has the statistical process capability to produce parts that will always meet our customer’s engineering drawing requirements. A CpK value is a statistical measure of the process capability – or in other words, it measures how close we are to our target specifications and how consistent we are around our average performance.
Since implementing SPC (Statistical Process Control) more than 15 years ago, our largest customers have found that using SPC, the resulting CPK (Process Capability) values indicate that 99.73% of the critical features of Brukar castings fall within the designated engineering specifications. As well, a PPM (Parts per Million) of 34 (34 rejects of out 1 million parts) is expected.
