Dot peen vs laser for deep VIN marking, what’s actually holding up for you?
I run a small fabrication shop and most of our parts need permanent IDs, mainly **VIN number marking** that has to survive blasting, coating, and rough handling.
We started with laser because it’s clean and fast, but once parts go through post-processing, the marks don’t always last. We moved more toward **dot peen marking** for **deep engraving**, which definitely helps with durability, but consistency can be tricky, especially on parts that aren’t perfectly flat or are semi-automated.
I’ve tried a few systems over time, including a **HeatSign** dot peen machine. Depth was solid, but I’m still comparing it against others like SIC to see what makes more sense long term, especially when it comes to setup and software.
Curious what others are seeing:
* How deep are you marking VINs?
* Any tricks for uneven surfaces?
* Anyone switch back to laser and regret it?
Just looking to learn from people actually running these day to day. Looking forward to you all suggestions!
