Brake Disc Hat Circumference Marking for Series Production

The following specifications are based on a real system example and serve for illustration. Actual parameters are customer-specific and individually adapted. This laser system meets the highest safety standards – including laser protection class 1, automatic shutdown, enclosed cabin, and integrated exhaust system for safe series production.

• Laser source: 100 W fiber laser InMarker (MOPA)
• Pulse duration: Variable – for controlled penetration depth
• Marking length: 42 characters
• Minimum depth: 0.1 mm
• Laser cycle time: 14 seconds
• Machine handling: 8 seconds
• Readability: visually detectable even after painting
• Control system: Siemens S7-1511 with TIA Portal 19
• Type selection: via Profinet or DIO signal
• Vision system: for rotational alignment of the brake disc
• DMC reader: with sorting function
• Safety features: Class 1 protection, maintenance door, exhaust system

The solution is flexibly scalable and suitable for various brake disc types – from cast iron to carbon-ceramic.

• Savings on consumables (as with dot peening or chemical baths)
• Proven series solution – already in use by renowned OEMs
• Easy integration – into existing production processes
• No complex R&D – ready for immediate use
• Reduced maintenance – thanks to contactless laser technology
• Global service organization – worldwide support without long wait times

With Trotec’s laser solutions, you rely on stable, low-maintenance, and future-proof technology that integrates seamlessly into your series production and meets the highest traceability requirements and the UN/ECE R90 standard.

Hat circumference marking is performed using a powerful fiber laser (100 Watt MOPA) – ideal for industrial applications.

• Variable – adjustable depth and intensity of laser penetration
• Powerful – ideal for fast marking in series production
• Contactless marking – no mechanical stress
• Permanent marking – readable even after painting
• Customizable content – e.g., serial number, production date, batch
• Inline-capable – no production stops for tool changes
• Robust and low-maintenance – designed for industrial series production
