Permanent Identification with Built-In Traceability
We design and build custom laser marking machines that fit your part, cycle time, and factory layout—complete with an integrated traceability system.
Each unit supports mark–read–verify: the laser marks a unique ID
(2D Data Matrix/QR/1D), a 2D code reader verifies readability and quality, and the record is written to a SQL database with full traceability.
A back-checking (process interlock) system prevents process skipping—downstream stations only run if the required mark and verification are present.
Key Features
Custom Laser Platforms
Fiber/CO₂/UV sources, fixed or galvo head, vision alignment, auto-focus; tailored marking windows and fixtures for your parts.
Mark–Read–Verify Loop
Immediate read-back by a 2D code reader with grading; automatic re-mark logic
and reject handling when quality is below threshold.
End-to-End Traceability
Unique ID generation, lot/serial linkage, operator/shift logging, and secure storage in SQL Server for audit and analytics.
Process Back-Checking & Interlocks
PLC-level gatekeeping to block the next step unless marking and verification pass; prevents skipped or out-of-sequence operations.
System Workflow
The system enforces a closed-loop
mark → read/grade → verify → interlock → log → visualize process to guarantee traceability and prevent skipped steps.
1. Part Presence
& Recipe Setup
Sensors/vision confirm part presence and orientation. Model/lot is selected (scan/MES), the correct laser program loads, and auto-focus/alignment sets the Z/XY.
2. Laser Mark Execution
The controller applies the recipe (text/logo/Data Matrix/QR/UDI/serial). Power, speed, and frequency are applied per model; serialization and checksum/ECC are generated.
3. Read & Grade Verification
An integrated 2D reader decodes and grades the mark
(e.g., ISO/IEC 15415/29158 criteria). Image capture is optional. Re-mark logic can trigger if grade falls below threshold.
4.traceability Write & Media Logging
A record is written to SQL Server: unit_id, model/lot, station, recipe, parameters (optional), result/grade, operator, timestamps, and mark image/reader snapshot for audit.
5. Process Interlock & Exception Handling
Back-checking at the PLC blocks the next station unless mark + verification pass. Fail paths support re-mark/reject with retry counters, reason codes, and escalation rules.
6. Visualization & Alerts
Dashboards display pass/NG rates, grading trends, and per-station status. Repeated fails/low grades trigger alerts to Microsoft Teams/email/your platform, with deep links to the relevant time window and unit ID.
