Mega and giga casting are profoundly changing how the automotive industry designs and manufactures structural components. Thanks to High-Pressure Die Casting (HPDC), it is now possible to produce complex, thin-walled and highly precise aluminum parts in a single shot.
This major breakthrough enables new designs and significant cost optimization. It also introduces a critical challenge: ensuring permanent, readable and reliable marking on parts that can be as large as a table.
In this context, marking is no longer a minor technical detail. It becomes a key condition for robust traceability, capable of following each component from casting through to final assembly.
When parts reach this scale, constraints change and conventional approaches quickly show their limits. Several factors make these applications particularly demanding:
From one cycle to the next, part geometry may vary slightly, directly affecting marking height. A fixed system can no longer guarantee consistent marking depth.
Marking surfaces may be recessed, angled or located in poorly accessible zones. Mechanical integration then becomes a real challenge.
Prototypes, IOD (Initial Outlay Design) parts and tooling all require clear, durable marking, without disrupting line organization or cycle times.
For these complex applications, SIC Marking combines several technologies to deliver reliable, industrial-grade traceability compatible with HPDC production constraints.
The marking head automatically adjusts its distance to the part.
This compensation ensures consistent marking depth, even with dimensional variations or large aluminum surfaces.
A mechanical compensation system keeps the laser at the correct focal distance.
This guarantees uniform, sharp and perfectly readable marking across the entire area, regardless of part topology.
An ideal solution for flexible environments:
Its full mobility complements integrated solutions and allows marking wherever reliability is non-negotiable.
These technologies are already in operation on large-part HPDC projects, supporting OEMs and Tier 1 suppliers from the foundry to final assembly, without impacting cycle time.
