1. Introduction
This project has been set up to fasten down the knowledge within the CCP about high precision injection moulding in relation to the Hewlett-Packard (HP) carriages. Two carriages for HP are developed for high precision injection moulding in co-operation with Philips Competence Centre Plastics. “Rogue” was a test case to develop a precision technology by injection moulding, fit for high precision in high volumes. In this case tolerances had to be attained, not by adjusting in the assembly line but by injection moulding. The results were the base for the development of the manufacturing process (part design, mould manufacturing, injection moulding process) for the “Carnegie” carriage.
With the goal to help HP in t
