Recently, Chongqing Chuke Intelligent Machinery & Equipment Co., Ltd. (hereinafter referred to as "Chuke Intelligent") successfully delivered a customized enclosed pneumatic dot-peen marking system to a leading domestic automotive parts manufacturer. Leveraging servo motor technology, the equipment achieved breakthroughs in both speed and precision, surpassing the performance of the international brand equipment previously used by the client. Thanks to its superior capabilities, the system earned the client's trust, resulting in immediate settlement of the final payment and the placement of a follow-up order.
The client is a benchmark enterprise in the field of critical automotive components, specializing in products such as steel engine pistons, steering knuckles, and precision forgings. Its products are supplied to major automakers and new energy vehicle brands—including JAC, Chery, Great Wall, BAIC, and BYD—and the company ranks among the global leaders in forged steel piston production capacity. The enterprise had long relied on imported marking equipment (specifically from SIC Marking) for marking components such as suspension springs, drive shafts, and engine pistons. Last year, the client purchased a marking machine from Chuke Intelligent for the first time; the equipment's reliable performance and lower operation and maintenance costs fostered a strong cooperative relationship between the two parties.
For this procurement, the client set rigorous technical requirements: the equipment had to feature an enclosed frame with multi-layer movable steel plates, offer an effective marking area of at least 200mm × 130mm, and match the marking speed of imported equipment. Prior to this, several domestic suppliers had participated in testing but failed to meet the speed requirements.
The field of pneumatic dot-peen marking generally faces technical limitations. Traditional equipment typically employs stepper motors with open-loop control and lacks position feedback; this often leads to positioning errors during high-speed operation, resulting in distorted markings and difficulties in scanning QR codes. To overcome this challenge, Chuke Intelligent utilized a Panasonic 400W servo motor to build the control system. The servo system relies on encoders for real-time position feedback and employs full closed-loop control. This approach boosts operating speed while ensuring precise positioning, successfully resolving the industry-wide dilemma of balancing speed and accuracy.
Field test results were impressive: when marking 100mm x 120mm QR codes, Chuke Intelligent’s equipment took just 7 seconds—outperforming imported equipment (9 seconds) and far surpassing other domestic models, which required 16 to 20 seconds for the same task. In a spot check of 20 samples using professional Keyence scanners, every QR code achieved the highest readability rating (Grade A), demonstrating excellence in both speed and precision.
Holding multiple international certifications—including ISO, CE, FDA, and RoHS—Chuke Intelligent specializes in the R&D and manufacturing of high-precision marking equipment, serving clients in over a hundred countries and regions worldwide. This collaboration once again underscores the technical prowess of domestic equipment. Moving forward, the company remains committed to advancing core technologies and delivering cost-effective, customized solutions to drive industrial upgrades—such as in automotive manufacturing—and propel domestic intelligent equipment into broader global markets.
