Gravotech: The Engraving & Marking Standard for Precision Industries

Fiber laser marking is optimal for high-speed, non-contact permanent marks on metals and certain plastics. It excels at creating 2D codes, serial numbers, and logos at speeds up to 8,000mm/s without consumable tooling costs. CNC engraving is preferable when you need physical depth (tactile marks), work with materials like brass nameplates, or require characters filled with paint. Many facilities use both technologies for different applications. Our application engineers can assess your specific materials and requirements to recommend the appropriate technology.

Across our three technology platforms, Gravotech systems process over 20 material families. Fiber lasers mark stainless steel, aluminum, titanium, copper, brass, anodized metals, and engineered plastics. CNC engraving handles brass, aluminum, acrylic, laminated substrates, and wood. Our laser tables cut and engrave acrylic, wood, leather, fabric, and composites. We maintain a materials testing laboratory and can evaluate your specific substrates before system selection. Contact our team with your material specifications for a complimentary marking assessment.

Yes. Our fiber laser marking systems are validated for UDI (Unique Device Identification) marking per FDA 21 CFR Part 801 and EU MDR 2017/745. We produce DataMatrix and GS1 codes that meet Grade A verification standards even after passivation and repeated autoclave sterilization cycles. Our application engineering team has experience validating marking processes for ISO 13485 quality management environments and can support your process validation documentation.

Mark permanence depends on the interaction between marking technology, material, and environment. For aerospace components exposed to temperatures exceeding 500 degrees Celsius, we use deep-engraving parameters that create marks 50-200 microns deep in the substrate, surviving thermal cycling and chemical stripping. For medical instruments requiring repeated sterilization, we employ oxide-layer marking that maintains contrast through 1,000+ autoclave cycles. Each application receives a tailored parameter study in our materials laboratory before production deployment. We provide documented test results demonstrating mark durability under your specific operating conditions.
