Guides on identifying parts that have to survive heat treatment, blasting, coating and casting — how marking methods and 2D codes compare, and how to choose one for your process chain.
Why part-level traceability on transmission gears breaks at heat treatment, sandblasting, and phosphating — and field results from a powertrain plant where laser-applied marks read at every step of the chain.

Read the guide ›Data Matrix and QR Code compared: structure, capacity and symbol size for the same data, error correction, scanning, the standards that specify each, and whether the two can be combined.
Read the guide ›Data Matrix explained for manufacturing: symbol anatomy, every size and capacity, GS1 Data Matrix, the standards that mandate it, and how marks are graded.
Read the guide ›QR, Data Matrix, PDF417, Aztec, MaxiCode and DotCode compared for manufacturing: capacities, grading standards, and what survives the process chain.
