Customer Request

An automotive & motorcycle mold manufacturing customer visited our facility for inspection and sample testing. Their core requirements are as follows:

The client for this collaboration is a supplier of automobile chassis parts in Hangzhou, specializing in die casting and precision machining of steel chassis components for both fuel and new energy vehicles, with products supporting multiple mainstream overseas automobile brands.

The client’s original marking equipment was a 50W fiber laser marking machine purchased in 2018, which exposed many production pain points during long-term use. The equipment required manual focusing and manual positioning calibration. Because steel chassis parts vary greatly in thickness and shape, each batch of products required repeated manual adjustment of the focal length, consuming a large amount of labor and working hours. At the same time, industry standards require marking depth to reach 0.25-0.30mm. The original laser equipment took as long as 100 seconds to mark a single piece, resulting in extremely low production efficiency and an inability to match the company’s large-scale mass production needs. The problems of outdated equipment, low efficiency, and high production costs seriously constrained the improvement of production line capacity. The client urgently needed a worry-free, cost-effective alternative marking solution.

Solution

In response to the client’s core needs for deep marking of steel chassis parts, batch production, and cost reduction and efficiency improvement, Chongqing Zixu Machine Works, which holds multiple technical certifications including ISO, CE, FDA, and RoHS and is a specialized and sophisticated enterprise, abandoned the traditional upgrade approach of high-power laser equipment. Relying on its local Chongqing marking machine R&D and manufacturing advantages, the company customized and delivered a complete desktop pneumatic marking machine solution with an electromagnet fixture for the client. As professional industrial marking equipment, it is suitable for deep marking scenarios in auto parts.

This equipment is based on the principle of pneumatic dot peen marking, using a computer to control the marking needle to strike the workpiece surface at high frequency, forming a dot matrix concave mark. It fully meets the standard marking requirement of 0.30mm depth, and the mark is corrosion-resistant, suitable for long-term traceability of auto parts. The equipment is equipped with a dedicated flat electromagnet fixture, requiring no complex clamping. Operators only need to place the workpiece and start the magnetic fixation to complete positioning, greatly simplifying the clamping process. At the same time, it is equipped with a long-amplitude marking needle with a vertical working stroke of 20mm, so conventional height differences of workpieces do not require fine adjustment of the equipment.

In terms of performance and cost, the advantages of this pneumatic marking machine solution are very significant. The marking time per piece has been reduced from the original 100 seconds to 30 seconds, increasing production efficiency by more than three times. Its deep processing performance can match laser marking equipment within 300W. The purchase cost of the entire set of equipment is less than 10,000 yuan, only one quarter of the price of the client’s original laser equipment, making it a cost-effective Chongqing marking machine solution. At the same time, Chongqing Zixu Machine Works. also provides the client with selection references for 100W and 300W auto-focus laser equipment, reserving ample solution space for the client’s subsequent production line upgrades.

Satisfaction

After the equipment was officially put into production, the results far exceeded the client’s expectations. With its professional pneumatic dot peen process, this high-performance marking machine produces clear handwriting and uniform depth, successfully passing quality inspection and traceability system audits. The exclusive electromagnet fixture and simple operation mode greatly reduce the manual operation threshold and debugging time, can save labor costs, and significantly improve production line turnover efficiency, fully demonstrating the manufacturing strength of Chongqing marking machines.

Compared with the old laser equipment, the new pneumatic marking machine solution has achieved a triple breakthrough in efficiency, quality, and cost, meeting the client’s production needs with extremely low equipment investment. The client highly recognizes the company’s customized, cost-effective marking machine solution, stable equipment performance, and professional technical service. At present, it has fully replaced the original manual laser marking process and will use this set of equipment as a standardized marking solution for chassis parts for the long term.

The implementation of this project for the Hangzhou auto parts enterprise is a classic case of Chongqing Zixu Machine Works. replacing traditional laser processes with its self-developed pneumatic marking machine to achieve cost reduction and efficiency improvement, fully demonstrating the hardcore strength of the local Chongqing marking machine brand. It not only solves the industry problem of deep traceability marking for automobile chassis parts, but also confirms the advantages of pneumatic marking machines in the field of precision heavy industry parts marking. In the future, Zixu Machine Works will continue to deeply cultivate the field of intelligent manufacturing for auto parts, continuously optimize marking processes and equipment performance, and continue to provide auto parts manufacturing enterprises with cost-effective and highly stable intelligent marking solutions, helping the manufacturing industry achieve high-quality, low-cost upgrading and development.
