Many people are familiar with the quality management process IQ, OQ, PQ, which I discussed in my last blog post, IQ, OQ, PQ in plastics manufacturing.  However, there is another important step, DQ, which ensures that the project or program is viable from the start.    

DQ or design qualification is the first step in process qualification that we perform.  During our DQ phase at Elite Plastics, we start with a kick-off meeting where the team spearheading the project introduces the opportunity.  Be it plastic decorating, elastomer compression molding or plastic injection molding, this allows all parties to get familiar with the project.  This is generally a short 15 minute meeting describing the basic outline and scope of the project.  Following the kick-off meeting there will be a variety of design reviews that include:

  • Tool design review
  • Tolerance review and print review
  • Secondary operation reviews

Based on these review’s, the team will meet again and perform a risk assessment outlining any high risk areas will need to be addressed.  After all of this information has been generated and documented, we can create a list of deliverables that is signed off prior to production launch.
