Facing the high quality and the high output requirements of die cast parts together with the high cost of die casting tooling, Dongguan Modern Metal Precision, P. R. China, started research on 3-D printed slide inserts.
For many products, a gradual aging of the insert surface leads to a reduction of local cooling in the casting. This effect led to shrinkage defects in the castings during production. The scrap rate after leakage tests reached 30%. In order to ensure the required casting quality, the slides often already had to be replaced after 20 to 30 thousand casting cycles, resulting in increased production costs.
Based on the analysis of MAGMASOFT® results, the objective was to achieve new cooling channel designs with the aim to improve the slide insert lifetime and to increase the efficiency of the current production.
