The paper shows how processing parameters of an injection transfer-moulding machine can be controlled to create and identify moulding faults of valve-stem seals. By controlling the processing parameters to produce typical valve-stem seal moulding faults at the system design stage, causes for waste can be identified. Detailed knowledge of the manufacturing process is fed into a knowledge based SPC quality system to monitor and control the manufacturing process. This information is used in the manufacture of valve-stem seals to improve quality and reduce waste.
