Dimensional and shape analysis of an additively manufactured DIEVAR tool steel mold component with a conventional design for die casting
Tomáš Sellner, Ladislav Socha, Miloslav RohPurpose
This paper aims to examine the dimensional and shape stability of an additively manufactured DIEVAR tool steel component used as a shape mold part for high-pressure die casting of aluminum alloys.
Design/methodology/approach
A conventionally designed component with an extended hexagonal shape was manufactured by selective laser melting (SLM), then heat-treated, machined and coated. The component was installed in a high-pressure die casting mold and tested in production. Dimensional and shape accuracy were monitored at selected stages using 3D scanning with a ROMER ABSOLUTE ARM and a THOME PRÄZISION 3D CNC coordinate measuring machine.
Findings
The results describe the dimensional and shape behavior of the SLM produced component across the manufacturing chain and during foundry operation up to 66,400 cycles. The component showed high rigidity and stability, confirming its suitability for severe thermal and mechanical loading in high-pressure die casting.
Practical implications
The findings support the use of additively manufactured component in die casting molds. The demonstrated dimensional stability provides guidance for designers and toolmakers when considering SLM-based tooling solutions.
Originality/value
This study offers an operationally validated case of a DIEVAR steel component produced by SLM and used as a functional mold part. It provides direct information on dimensional stability under real cyclic loading and contributes to more informed application of additively manufactured tooling components.
