Characterisation of Feedstocks by Injection Moulding

摘要

A machine based test method for characterising feedstocks has been initiated and can be carried out on different moulds. A batch test before the start of production clearly shows whether parameter changes must be performed, so that the production of PIM parts can continue smoothly. If the test data are collected and compared over a prolonged time period, acceptable charge-fluctuation ranges can be determined, without injection moulding parameter changes. New injection parameters can then be developed for batches which lie outside the range.
