Quality has become a core characteristic for businesses to differentiate themselves from their competitors. Many manufacturers compete in the injection molding sphere. Manufacturing facilities try to produce parts that meet the customer expectation by considering core requirements which are uniquely different from one customer to another. The company in which the project is conducted specializes in precision injection molding and assembly. These specifications range from design assistance to production and final assembly. Applications served are typically very critical in nature, requiring the most demanding specification and tolerance. As an industry pioneer, the company has continually struggled to keep up the level of quality it has been known for. They have had problems with molding processes, customer complaints, and providing defect free products. This project analyzed the entire process from the planning and defining to product design and verification, process design and development, and product and process validation. The proper application of the Advanced Product Quality Planning (APQP) shows improvement in the process of satisfying the customer’s need, reduction in defect rates and provides opportunity for continuous improvement.
