Quality Assurance

Our Philosophy

Of all the activities that make up the manufacturing process, quality assurance is the most vital. However, to truly assure the quality of the manufacturing process, perfect knowledge of the design intent for fit, form and function is necessary. Gathering this information and conceiving an error proofing strategy to deliver 100% conformance to your requirements is what we do.

Quality Assurance

We at Grand Traverse Plastics Corp. believe that our quality performance is no accident. Our external DPPM performance is the result development and deployment of manufacturing processes that have error proofing strategies "designed in" that prevent non-conformance in the most critical fit, form, and functional areas of the component.

Quality Policy:

At Grand Traverse Plastics our quality policy is simple and straight forward: quality through involvement and continuous improvement.
