Overcoming Common Wax Injection Problems: The First Step Toward Automation

摘要

A requirement for automated injection of wax patterns is the ability to make defect-free patterns. MPI collaborated with two US foundries in 2015 to demonstrate how quality dies combined with the proper application of process controls can eliminate common wax injection defects. The results were a dramatic reduction in scrap, reducing both operating costs and rework costs while dramatically increasing throughput. In both collaborations, the customer realized a corresponding casting yield increase. In one case, the success of eliminating scrap from the wax injection process opened the door to automation of the wax injection of this family of parts. Where applicable, the ICI Atlas of Wax Pattern Defects, as well as the ICI Process Control course materials is referenced.
