Jiangmen Chaoyang Precision Manufacturing Co., Ltd

Master the core technology of ceramic cylinders

Jiangmen Chaoyang Precision Manufacturing Co., Ltd. (hereinafter referred to as "Chaoyang Precision"), a Taiwanese funded enterprise located in Jiangmen High tech Zone (Jianghai District), has mastered the core technology of ceramic cylinders and successfully established a provincial-level motorcycle power component engineering center in 2017. It has 41 patents and has participated in the formulation of national industry standards multiple times.

Chaoyang Ceramic Cylinder combines ceramic materials with other composite materials to create new materials, which are then combined with new processes to evenly coat the inner wall of the cylinder. Through a series of deep processing, it achieves thin, light, hard, ultra wear-resistant, and ultra high temperature resistant effects. This technology is at the level of aviation batch application and far ahead of its peers. As the core of aviation engines, the Chaoyang ceramic cylinder is applied in national heavy weapons (such as the Yilong drone), exported as a national business card (the core component of dual-use drones), and participated in practical combat, achieving good results.

"The ceramic film thickness of Chaoyang ceramic cylinder is 50-125 times thinner than ordinary cast iron; the weight of the ceramic film is more than 30 times lighter than ordinary cast iron; the friction coefficient of the ceramic film is 6 times lower than that of cast iron cylinder; and the hardness of the ceramic film is 3 times that of cast iron cylinder," said Liu Yangyang, the project leader.

At present, Chaoyang ceramic cylinders have been successfully applied in fields such as drones, manned aircraft, high-speed rail, state guest vehicles, police cars, industrial air compressors, large displacement motorcycles, garden machinery, etc. They have also served as the core of state guest vehicle engines and the core of attack 1 drone engines, participating in military inspections and receiving reviews from the Party and the people. In addition, Chaoyang ceramic cylinders have made significant breakthroughs in the field of manned aircraft, obtaining airworthiness certificates for manned aircraft in France and Germany. The Civil Aviation Administration of China also went to the company in August 2022 for the airworthiness certification of manned aircraft, and it has been successfully completed. At present, Chaoyang Precision is producing more than 140 types of ceramic cylinders, including 21 types for aviation. It has established long-term cooperative supply and demand relationships with famous brands such as Northwestern Polytechnical University, Beijing Institute of Technology, Zongshen Aviation, Chunfeng Power Research Institute, and Lifan Vehicle Research Institute.

"The successful development and application of Chaoyang ceramic cylinders have led the market in large displacement motorcycles, as well as in unmanned aerial vehicles and small manned aircraft. At the same time, they have made positive contributions to weight reduction and wear resistance of aircraft engine cylinders, and the future market is broad," said the project supervisor.

Nowadays, Chaoyang Precision is using its own strength, looking at the overall situation, adhering to the principle of establishing and strengthening enterprises through technology, and steadily moving towards a technology leading company.

Taishan Zhongmagnesium Technology Co., Ltd

Solving the problem of lightweight automotive components

The field of energy-saving, environmentally friendly, intelligent and comfortable new energy vehicles is the key development direction of Taishan Zhongmagnesium Technology Co., Ltd. (hereinafter referred to as "Zhongmagnesium Technology"). In this rapidly developing track, China Magnesium Technology has explored and practiced new molding processes, magnesium alloy materials, and weight reduction design to solve the problem of lightweight automotive components and achieve weight reduction goals under the premise of safety.

Established in 2018, Zhongmagnesium Technology has been focusing on the development, research, production, and application of new magnesium alloy materials and lightweight applications for a long time. "The integrated magnesium alloy products produced through liquid forging equipment have the characteristics of small grain size, compact structure, high strength, good surface smoothness, uniform performance, less cutting, high blank quality, and lightweight, which can meet the needs of lightweight, high-quality, and high heat dissipation of new energy vehicles." The relevant person in charge of China Magnesium Technology stated that in 2021, China Magnesium Technology passed the IATF16949 system certification and currently has 22 sets of cold chamber die casting islands, 3 sets of semi-solid die casting islands, and 2 sets of liquid forging extrusion islands. It can provide solutions in all aspects of new forming processes, new magnesium alloy materials, and weight reduction design.

The molding process of Zhongmagnesium Technology has achieved technological breakthroughs and innovation. One is low-speed pouring, which enters the material pipe and mold cavity through low-speed laminar flow, effectively preventing air from being drawn in. The second is pressure forming, where the injection speed is 0.04 to 0.3m/s under instantaneous pressure, and the pressure at high speed quickly deforms the fully vented metal liquid in the mold cavity. The third is secondary pressurization, which makes the structure of deformation solidification more precise. The fourth is to add a dual cylinder ejection device. Before demolding the product, the dual cylinder ejection device can achieve fine-tuning of the forming structure, which can further improve surface smoothness, dimensional accuracy, etc. At present, within 2 minutes of producing a single component, under the same efficiency as die casting, the yield of the component produced by liquid forging and extrusion can reach over 95%.

In recent years, China Magnesium Technology has also adopted cooperation with domestic and foreign research institutes to continuously develop and grow in technological innovation and promote industry university research. Starting from 2020, the company has reached strategic cooperation with Academician Pan Fusheng's team and the Automotive Structure and Safety team of Central South University of Technology, establishing the Magnesium Alloy New Materials Research Institute and the Automotive Lightweight Application Research Institute to promote industrial upgrading and development.
