During project planning it is very important to ensure that each of the parts will be produced consistently. To do this, the manufacturing process must be qualified to ensure that it is repeatable and stable, both dimensionally and cosmetically. At GMN Plastics, this qualification process is broken down into four sections including design qualification, installation qualification, operational qualification and performance qualification. We will explain them in further detail below:
Design qualification (DQ) - During this initial stage, GMN Plastics receives the design print and goes through a tolerance review to determine whether the tool can be built as the customer has requested.
Installation qualification (IQ) - The GMN Plastics team then begins qualifying how to install the tool so that the process can be repeated in the same way during future production runs.
Operational qualification (OQ) - At this point, design experiments are conducted and variables are tested to identify where the part is best suited to run. To do this, parts are taken from multiple conditions and are submitted to metrology for measurements. Based on the measurement results, the next step is performance qualification.
Performance qualification (PQ) - Finally, features, dimensions and cosmetics are evaluated. The production process is run and a predetermined number of parts are randomly selected and inspected by metrology to measure whether the process is deemed to be both repeatable and reliable.
One strength of GMN Plastics is the high quality standards that are adhered to. To uphold these standards, our team goes through this series of qualification steps for every project to ensure that parts meet our customer’s needs.
