Quality

Keystone (KFH) is a high quality manufacturer. Our Quality Management System is ISO 9001:2015 certified and has been since 2003. We strive to hold high quality standards and regularly receive outstanding quality reports from our customers. Our parts per million rejects rates are very low. Usually below 25 ppm. In the rare instance where there is a quality problem, our quality manager or one of our 4 engineers work closely with the customer to resolve the issue as soon as possible. Quality at Keystone starts at the beginning. First, we design and build high quality stamping tools.  Then, tool wear is monitored and wore tool parts are replaced with new parts that we manufacture.  All production is inspected using certified measuring tools in our Quality department. Additionally, operators check and monitor critical dimensions throughout production. Our entire workforce is dedicated to making a quality product and this is all done in Pennsylvania in the USA.
