On November 5, 2025, Chongqing Chuke Intelligent Machinery Equipment Co., Ltd. (hereinafter referred to as "Chuke Intelligent") welcomed a delegation from an international auto parts company. The client traveled to Chongqing specifically to test the application effect of its independently developed 10W
UV Laser Marking Machine in the field of QR code traceability for auto parts. After several hours of precise marking and in-depth verification, the equipment, with its superior performance of "cold processing, high precision, and zero thermal damage," successfully completed the QR code assignment of complex curved surface parts and achieved efficient association of traceability information throughout the entire lifecycle. A preliminary cooperation intention was reached on-site.
The auto parts tested included high-precision components such as shock absorber springs and aluminum alloy brackets, made of materials including high-strength steel, coated alloys, and engineering plastics, with surfaces mostly featuring curved or irregular shapes. Traditional fiber laser marking is prone to material deformation and coating scorching due to thermal effects, while inkjet printing carries the risk of label detachment, becoming a pain point in the industry's traceability management.
The Chuke Intelligent Third Generation 10W UV
Laser Marking Machine (CK-UV-10W) utilizes 355nm wavelength cold light source technology, with a focused spot diameter of only 15 micrometers and a heat-affected zone of less than 0.05 millimeters. It can precisely peel off metal plating or plastic surface coatings without damaging the substrate. In on-site testing, the equipment, scanning at a speed of 0.08 mm/s, simultaneously engraved bilingual (Chinese and English) markings, production batch numbers, and dynamic QR codes on an 8mm diameter shock-absorbing spring surface. The marking contrast reached 95%, the scanning success rate was 100%, and the surface roughness Ra ≤ 0.5 micrometers, fully complying with the automotive industry's ISO/TS 16949 quality standard.
“Dynamic beam adjustment technology is our core advantage,” explained the technical director of Chuke Intelligent. The equipment's AI vision positioning system can identify the curvature of parts in real time and automatically correct the laser energy density, with an error controlled within ±0.01 millimeters. “Even on irregular surfaces, it ensures sharp edges and complete information on the QR code, something traditional equipment cannot achieve.”
During testing, the customer focused on verifying the ability to link QR codes with information throughout the entire lifecycle of automotive parts. Through Chuke Intelligent's "one item, one code" traceability system, each QR code can be linked to over 20 data items, including raw material batches, production processes, quality inspection reports, logistics information, and after-sales maintenance records. For example, scanning the QR code on an aluminum alloy bracket reveals that its raw materials came from a German supplier, underwent three heat treatment processes and two non-destructive tests before being put into storage, and can subsequently be traced to any after-sales service point worldwide.
“This transparent management will help us reduce quality risks,” said the client’s quality director. Previously, the mis-installation rate of parts due to unclear labeling was as high as 3%, while Chuke Intelligent’s solution can reduce this figure to below 0.1%. “More importantly, it provides critical infrastructure for the digital transformation of smart factories.”
This collaboration is not Chuke Intelligent’s first foray into the automotive sector. In the first half of 2025, the company provided an autofocus
Uv Laser Marking machine to a Turkish automotive shock absorber spring manufacturer, increasing the yield rate from 65% to 99%; and customized an automated laser welding production line for Indian automobiles, increasing single-line capacity several times over.
“Our goal is to make Chinese laser technology a ‘standard configuration’ in high-end production lines globally,” revealed Xiao Renmin, Chairman of Chuke Intelligent. The company is currently developing a picosecond-level UV laser, expected to enter mass production in 2026, which will further break through the limits of ultrahard material processing.
With the successful completion of this test, Chuke Intelligent’s 10W UV laser
Marking Machine will soon be deployed in batches at the client’s production bases in China and Southeast Asia, injecting new momentum into quality traceability and intelligent manufacturing in the automotive industry. This is just another milestone in China's journey of "going global" with high-end equipment.
