Automatic VIN Marking Machine for Smart Automotive Manufacturing
Introduction
In automotive manufacturing, the Vehicle Identification Number (VIN) is more than a regulatory requirement—it is the backbone of traceability, quality control, and anti-counterfeiting. As body-in-white (BIW) structures increasingly use high-strength and hot-formed steels, traditional marking methods struggle to achieve the depth and durability needed for lifelong identification. An automatic VIN marking machine addresses this challenge by combining high-power laser technology with automated handling and intelligent vision systems. This article explains how such systems work, their key features, and why they are essential for smart manufacturing environments.
Product Overview
The KINMARK Deep Laser Marking Machine is an automatic VIN marking solution designed for high-strength steel plates with yield strength exceeding 700 MPa and hot-formed steel plates up to 1500 MPa. It achieves a marking depth of more than 0.2 mm on body-in-white, ensuring permanent, legible VINs that withstand painting and rubbing processes. The system supports integration with industrial robots or assisted manipulators, making it suitable for automated production lines in automotive manufacturing.

Working Principle
The automatic VIN marking machine uses a 200W laser to create deep, permanent marks on high-strength steel. The focused laser beam melts and vaporizes the material surface, forming a recessed VIN with a depth greater than 0.2 mm. This depth ensures that the VIN remains readable even after painting and rubbing. The system can be equipped with an optional 3D vision guidance system for precise positioning, enabling accurate marking on complex geometries. Additionally, an optional 3D laser scanning measurement and OCR recognition system provides online inspection of marking quality, ensuring 100% traceability.
