Donghua Test: structural mechanics test leader, force sensor leading in China

KJ3102X1-BA1 Donghua Testing is a leading structural mechanical properties research and electrochemical workstation overall solution provider in China. The company was founded in 1993, 30 years has always focused on intelligent measurement and control system research and development, production and sales, master the core technology, product maturity and independent intellectual property rights, so as to be widely recognized by the market, more than 60% of the products used in the national defense industry. In 2007, the company acquired Shanghai Donghao Test Technology Co., LTD., and laid out PHM (fault prediction and health management) related business; In 2009, Yangzhou Dongrui Sensor Technology Co., Ltd. was acquired to further expand the sensor business. In 2013, Jiangsu Donghua Analytical Instrument Co., Ltd. and Jiangsu Donghua Calibration and Testing Co., Ltd. were invested in the establishment of electrochemical workstation, AC impedance test system business and calibration and testing business respectively.

KJ3102X1-BA1 The company takes structural mechanics testing as the core and develops multi-business synergies. The company focuses on the research and development, production and sales of structural mechanical performance testing instruments and supporting software, and provides application solutions and technical services. Through continuous expansion, the company has formed four major product lines: structural mechanical performance test and analysis system, structural safety online monitoring and defense equipment PHM system, equipment intelligent maintenance management platform based on PHM, and electrochemical workstation, and is promoting the development and production of custom measurement and control analysis system. 1) Study on structural mechanical properties: The company’s structural mechanical properties research business focuses on structural strength KJ3102X1-BA1 test, fatigue test (life assessment), dynamic characteristics analysis (natural frequency, vibration mode, damping ratio, modal stiffness and mass), accurate prediction of the impact of environmental excitation on structures, etc., which is widely used in aerospace, vehicles and ships, civil construction, engineering machinery, energy and electric power and other fields. It has become an indispensable scientific instrument product in the industrial field. After years of research and development and technology accumulation, the company has mastered the core technology related to the field of structural mechanical performance testing, and has become an industry leader.

2) Structure safety online monitoring and defense equipment fault prediction and health management (PHM) : The company’s PHM business is based on new technologies such as intelligent sensing, cloud computing, big data and 5G, and carries out real-time monitoring, safety assessment and health management for structures such as bridge beams, large buildings, water conservancy projects, port machinery and major equipment. With the increasing complexity of engineering systems in various fields, the demand for PHM business with forecasting technology as the core is rising, the company is one of the few domestic service providers with software and hardware technology research and development, production capabilities, and can provide PHM business related system solutions. 3) Equipment intelligent maintenance management platform based on PHM: Shanghai Donghao, a wholly-owned subsidiary of the company, can provide PHM-based equipment intelligent maintenance management software platform solutions to achieve comprehensive equipment maintenance management with predictive maintenance as the core, equipment and spare parts management in the whole life cycle, digital work order management and professional performance index management. It can provide customers with customized equipment maintenance management and remote care services, which is an essential part of the construction of smart factories. 4) Electrochemical workstation: Electrochemical workstation is analyzed by measuring the electrical signal of the response of the system to be tested while applying the excitation signal. Donghua Analytica, a wholly-owned subsidiary of the company, focuses on the research and development, production and electrochemical application of electrochemical workstations, and has nearly 30 years of technical accumulation in the field of test technology and application. Its products are widely used in the KJ3102X1-BA1 electrical analysis of electrode materials/solutions/sensors, AC impedance testing of single battery/lithium battery stack/fuel cell stack at static or dynamic conditions. 5) Custom measurement and control analysis system: The custom measurement and control analysis system will integrate test and control, mainly composed of sensors, measurement and control system hardware, analysis and control software platform, widely used in aerospace, electronic power, vehicles and other fields, the downstream demand level continues to increase. The company is one of the few domestic enterprises with relevant technical capabilities.

Donghua test revenue and net profit to the mother grew rapidly. From 2013 to 2022, the company’s revenue grew rapidly as a whole. Although the company’s performance was dragged down by the downward market demand caused by the macroeconomic impact around 2016, it realized a rapid rebound and maintained a high growth level after 2017. In 2022, the company’s operating income and net profit returning to mother will be 367/122 million yuan, with a growth rate of 42.80%/52.50% respectively, and the CAGR of revenue and net profit returning to mother from 2013 to 2022 will be 17.34%/24.48% respectively. By the end of Q3 2023, the company achieved operating income and net profit of 306/82 million yuan, with an increase of 37.04%/47.92%, mainly due to the rising demand for localization, the company’s leading technology and multi-business sector development strategy.
