In the wave of intelligent manufacturing and upgrading of new energy heavy-duty trucks, the identification of every component carries crucial information for quality traceability, assembly accuracy, and after-sales maintenance.

A leading new energy truck manufacturer introduced a total of 10 Ray Source 50W handheld laser marking machines in 2025 and 2026, achieving a comprehensive upgrade in the marking process of mechanical components and completely eliminating the drawbacks of traditional labeling methods. Let's take a look at the smart manufacturing site of Ray Source and witness the transformation brought by laser marking.

01 Customer Background I Strict Requirements for Identification in New Energy Heavy-Duty Truck Manufacturing 

**Xiangke Technology specializes in the research, development, and manufacturing of new energy heavy-duty trucks. It conducts research and production of the core three-electricity (battery, electric drive, and electronic control) systems for new energy heavy-duty trucks. A large number of mechanical components, such as the factory coding information marked on the end cover of the electric drive bridge motor, are used for quality traceability, assembly error prevention, after-sales maintenance, and other purposes.

Therefore, the clarity, durability, and data accuracy of the markings are directly related to the quality control level of the entire vehicle and the operational efficiency of the production line.

02 The Pains of Tradition I: The "Double Dilemma" Marked by Tradition. Through in-depth exchanges with the production team of this new energy heavy-duty truck manufacturer, we learned that the original methods involved label pasting and desktop machines, but both had the following issues: Label pasting: * Poor durability. The areas near the motor and battery pack of heavy-duty trucks experience high temperatures, making them prone to detachment and wear.

*Mechanical components often have oil stains, which can penetrate the adhesive layer of labels, causing labels to fall off or the writing to become illegible.

*The operating environment of heavy-duty trucks is harsh, often causing the handwriting on labels to wear off, making it impossible to trace.

Although bench marking machines are more durable than labeling machines, they face significant limitations when dealing with large, heavy, and irregularly shaped components of new energy heavy-duty trucks: * The components of heavy-duty trucks can be very large, and bench equipment has poor mobility, making it unable to meet the needs of large workpieces. * The marking positions are limited, the operation is not flexible enough, and fixed marking stations are difficult to adapt to adjustments in the heavy-duty truck production line.

03 Voice of Demand | What kind of marking solution do heavy-duty truck manufacturers want?

Facing the aforementioned pain points, the enterprise has clearly outlined the following requirements: ① Permanent and clear identification: resistant to oil stains and wear, with traceability throughout the entire lifecycle; ② Significant efficiency improvement: capable of marking a single item 10 times, achieving shorter time and deeper depth compared to the same period last year; ③ Flexible adaptation: adaptable to components of different sizes and materials, eliminating the need for frequent adjustments; ④ Intelligent integration: capable of linking with MES systems, automatically uploading data, and achieving traceability.

04 The Way to Break the Deadlock | After multiple rounds of technical exchanges and testing

the head heavy-duty truck manufacturer ultimately chose the 50W portable handheld laser marking machine from Ray Source. This equipment, characterized by high power, flexibility, portability, and intelligent interconnection, perfectly meets the needs of the enterprise.

Pain Points:

- Portable laser solution from LASER-ZONE prone to detachment

- Fiber laser marking results in permanent character etching, offering wear and corrosion resistance with lifelong traceability

- Low efficiency: Despite its 50W high power, it takes 10 attempts, each lasting 5 seconds, with significant manual intervention

- Handheld design eliminates the need to move the workpiece, allowing for flexible operation by a single person and seamless integration with the system

- Proprietary Linux system supports secondary development and has been successfully integrated with MES systems, ensuring automatic data upload

- Environmentally friendly: No consumables required, complies with EU RoHS standards, promoting green manufacturing

- Product Line Adaptability: Replaceable lithium battery supports simultaneous charging and use, ensuring uninterrupted production for two shifts

05 Quantitative Achievements | Data Witnesses Value Since the introduction of the firstLZY handheld laser marking machine 

in July 2025, a total of 10 marking machines have been introduced by this leading heavy-duty truck manufacturer by February this year, leading to a tremendous change in its marking process. The following are the production data: Efficiency Improvement: · Marking Speed: Increased from 2 minutes per piece to 55 seconds per piece; · Equipment Stability: Continuous operation without malfunction, with an average daily marking output exceeding 1,000 pieces;

Cost savings: · Consumable cost: The cost per unit has been reduced from 0.5 yuan to 0 yuan, resulting in annual savings of over 200,000 yuan; 

Labor cost: Reducing 2 operators saves approximately 150,000 yuan in annual labor costs;

Through case studies, it is proven that a successful marking upgrade brings not only "clearer and faster marking", but also a leap in production line efficiency, optimization of labor costs, implementation of eco-friendly manufacturing, and extension of intelligent management. Laser marking is becoming an indispensable link in the intelligent manufacturing chain of new energy commercial vehicles.

06 Technical Highlights | Why doesLZY stand out compared to its competitors?

➊ 50W/60W/100W power options: Compared to the mainstream 20W/30W handheld devices on the market, the marking speed is significantly improved. Materials such as dark-colored metals, galvanized parts, and aluminum alloys can be molded in one go without the need for repeated processing.

It is worth mentioning that theLZY 100W portable handheld laser marking machine is an industry pioneer. Currently, there are no products in the same power range on the market, and it can meet the marking needs of higher efficiency, deeper etching, and stronger materials, providing stronger power support for high-end manufacturing scenarios.
