On April 10th, a group of new guests—reporters from mainstream media outlets such as Rednet Moment, New Hunan, and Changsha Evening News—gathered in the conference room of Yipai CNC Co., Ltd. in Changsha for an exclusive interview with Mr. Zhu Genghong, chairman of Yipai CNC. Chairman Zhu introduced to the media that Yipai CNC's products primarily follow a customized path, closely tracking market demands. Let's take a look at how Yipai CNC is perceived by these reporters.

Yipai CNC successfully launched the first domestically produced automatic defect detection equipment for mobile phone cover plates.

R&D of Elliptical Lathe Breaks Through Difficulties and Breaks Foreign Monopoly

Under the enthusiastic guidance of Chairman Zhu, reporters from Rednet Moment visited Yipai CNC's workshop and toured the company's CNC piston elliptical lathe project. This project allows for more flexible and precise control over the processing shape of high-power marine diesel engine pistons. The CNC piston elliptical lathe is a special type of heavy-duty equipment used for processing high-power marine diesel engine pistons. Chairman Zhu explained that high-power marine diesel engines are key components of ships, and pistons are key parts that have a decisive impact on engine performance. Previously, China's traditional piston processing technology used mechanical imitation, a method whose efficiency and precision were far lower than international advanced levels. Now, Yipai CNC uses linear servo technology and improves the lathe's control system to more flexibly and precisely control the piston processing shape, effectively improving its precision by one level and efficiency by double. This means a technological bottleneck that has long restricted the development of China's giant ship engines has achieved a significant breakthrough.

Previously, the processing technology for high-power marine diesel engine pistons was monopolized by two foreign giants, MANB＆W and Wartsila, which severely restricted the development of China's giant ship engines. The successful R&D by Yipai CNC broke the foreign monopoly on this technology. This technology won the "Second Prize of the 2016 China Machinery Industry Science and Technology Award" and is of great significance to China's national defense and civilian industries.

Mobile Phone Cover Plate Detection: Sharp Eyes That See Microscopic Defects

In an exchange with Rednet reporters, Chairman Zhu stated that in addition to customized services for lathe projects, Yipai CNC has now also opened customized services for automatic defect detection equipment for mobile phone cover plates. This service allows for personalized customization while ensuring production capacity, interpreting the connotation of flexible manufacturing, providing data support for enterprise transformation and upgrading, and aiming to create intelligent products. From "high-end" to "down-to-earth," the company is building a highly flexible intelligent manufacturing workshop. The company has successfully launched the first domestic automatic defect detection equipment for mobile phone cover plates, which can replace manual inspection, with a production cycle of 6 seconds per plate. This avoids eye damage to workers from strong inspection lights and greatly improves production efficiency. This equipment will be shipped to a mobile phone cover plate manufacturing company in Dongguan next week.

“This is a humane innovation. On the one hand, a large amount of manpower input, while increasing costs, cannot effectively guarantee the pass rate of quality inspection; on the other hand, quality inspection requires workers to observe the appearance of mobile phone cover plates under strong light for a long time, which will affect the eyesight of the inspectors. These factors prompted Yipai CNC to seek new breakthroughs. Sharp eyes that see microscopic defects,” Chairman Zhu emphasized.

Chairman Zhu further introduced that this equipment mainly uses a human-like visual method for automatic identification. The high-resolution camera installed on the equipment acts as the human eye, and then the system accurately analyzes the images captured by the camera based on different algorithms to achieve automatic detection. This is the same as the manual judgment process, relying on the eyes to capture the image and then letting the brain process it to get the result, but the machine is more accurate and efficient than manual operation. This equipment can perform high-performance quantitative detection of defects in mobile phone cover plates, with the accuracy of multiple defect detections exceeding 99%, reaching a domestically advanced level and breaking foreign technology monopolies.

Reporters from New Hunan interviewed and reported on Yipai CNC's constant temperature workshop. The picture shows Yipai CNC technicians operating the first domestic automatic defect detection equipment for mobile phone cover plates on-site.
