Automotive Laser Marking Machine Applications
Introduction
Laser marking has become a core process in automotive manufacturing, where every vehicle body, powertrain component, and safety-critical part must carry a durable, readable, and traceable identification code. Among the different marking technologies available, the automotive laser marking machine is widely used because it produces permanent marks without consumables, tool contact, or mechanical wear. KINMARK provides a range of laser marking machines for industrial identification applications.
In vehicle assembly, marking is not only about printing a number. The Vehicle Identification Number (VIN) must remain legible after painting, rubbing, and years of service. On modern body structures built from high-strength steel and hot-formed steel, conventional marking methods often struggle to reach the required depth. This is where deep laser marking systems are applied.
This application guide reviews the main applications of automotive laser marking machines, how deep VIN marking works on high-strength materials, where these systems are integrated in production lines, and what engineering teams should consider during selection and integration.
Product Overview
A deep laser marking machine is a marking system designed to create permanent identification marks on metallic surfaces, including high-strength steel plates and hot-formed steel plates used in vehicle body construction. It is used in automotive mass production environments where marking depth, mark stability, and traceability are required.
The KINMARK Deep Laser Marking Machine is developed for deep VIN marking on high-strength materials. According to the product information, the system can mark VIN codes on steel plates with yield strength exceeding 700 MPa and hot-formed steel plates with strength up to 1500 MPa. The marking depth on body-in-white can reach more than 0.2 mm.
The system is positioned for automated production lines. It supports integration with industrial robots or assisted manipulators through different mounting interfaces, and optional vision and inspection modules are available for positioning and traceability. These capabilities support broader automotive marking solutions.

Working Principle
A laser marking machine uses a focused laser beam to modify the surface of a metal workpiece. In deep marking applications, the laser energy is controlled to remove or displace material to a defined depth, creating a mark that remains readable after subsequent processes such as painting and rubbing.
For VIN marking on body-in-white, the marking depth is a critical quality characteristic. The KINMARK deep laser marking process is designed to produce a marking depth greater than 0.2 mm on high-strength steel. A special marking process is applied to ensure clear rubbing results after painting, which supports the legal and traceability requirements of vehicle identification.
The system can be integrated with a robot or an assisted manipulator. Optional 3D vision guidance supports precise positioning before marking. Optional 3D laser scanning measurement and OCR recognition can be used for online inspection of marking quality and to support traceability.
