The process of any long-term cooperation is not smooth. The cooperation between China Chungfo Fan and the well-known treadmill manufacturer has also experienced some small episodes and challenges, but it is precisely these episodes that further highlight the professional ability and sense of responsibility of China Chungfo Fan, and also make the cooperation between the two parties closer and more solid. In the early stage of cooperation, according to the R&D needs of its new type of treadmill, the customer put forward two special requirements for the small cross flow fans 50100 and 50200, which brought certain challenges to our production and R&D. However, with strong technical strength and efficient execution ability, China Chungfo Fan successfully solved these problems and won the customer's trust and recognition.

The first challenge is that the customer requires optimizing the size and installation method of the fan to adapt to the internal structure of its new type of treadmill. In order to pursue a smaller and more fashionable appearance design, the customer's new type of intelligent treadmill has optimized and compressed the internal space. Although the size of the original small cross flow fans 50100 and 50200 is relatively small, it still cannot perfectly adapt to the internal installation space of the new type of treadmill. At the same time, the customer requires the installation method of the fan to be more convenient and firm, reducing the installation process and improving production efficiency. After receiving the customer's needs, China Chungfo Fan attached great importance to it and immediately organized the technical team to carry out special research, optimizing the size and installation structure of the two fan models 50100 and 50200. The technical team first made a detailed understanding and measurement of the internal structure of the customer's new type of treadmill, accurately grasped the size requirements of the installation space, and then combined with the heat dissipation performance needs of the fan, optimized and adjusted the size of the fan's shell, fan blade and motor. On the premise of not affecting the fan's heat dissipation efficiency, noise control and service life, the overall size of the fan was reduced by 10%. At the same time, the installation interface and fixing method were optimized, and a snap-on installation design was adopted to make the fan installation more convenient and firm, reducing the customer's installation process and improving production efficiency. After the optimization design was completed, the technical team quickly made samples and sent them to the customer for testing. After multiple rounds of testing by the customer, the size, installation method and heat dissipation performance of the samples fully met the customer's needs, successfully solving this challenge.

The second challenge is that the customer requires improving the high-temperature resistance of the fan to adapt to the long-term high-load operation needs of the treadmill. The customer's commercial treadmills often need to run continuously for a long time, and in some scenarios, the daily operation time is more than 12 hours, which leads to a significant increase in the heat generated by the core components inside the treadmill and a higher ambient temperature, putting forward higher requirements for the high-temperature resistance of the DC cooling fan for Treadmill. The customer reported that during the preliminary testing process, after some fans ran at high load for a long time, problems such as severe motor heating, reduced speed and reduced heat dissipation efficiency occurred, which could not meet the use needs of commercial treadmills. They required us to optimize the products in a short time to improve the high-temperature resistance. After receiving the customer's feedback, China Chungfo Fan immediately organized the technical team and quality control team to carry out analysis and investigation. After detailed testing and analysis, it was found that the main reason for the insufficient high-temperature resistance of the fan was that the temperature resistance level of the motor and the temperature resistance of the fan blade material could not fully adapt to the long-term high-load operation environment of the commercial treadmill. In response to this problem, the technical team formulated a special optimization plan, increasing the temperature resistance level of the fan motor from 105℃ to 125℃, selecting motor coils and bearings with better high-temperature resistance, and replacing the fan blade material with high-temperature resistant engineering plastics to improve the temperature resistance and stability of the fan blade; in addition, the technical team also optimized the air duct design of the fan, improved the air circulation efficiency, and further reduced the self-heating of the fan during operation. After optimization and adjustment, the technical team carried out a long-term high-load temperature resistance test on the fan, simulating the actual operation environment of the commercial treadmill, allowing the fan to run continuously for more than 24 hours. The test results showed that the fan ran stably, the motor heated normally, and the speed and heat dissipation efficiency remained stable, fully meeting the customer's needs. In the process of solving this problem, we not only quickly responded to the customer's needs, but also took the initiative to feedback the problem causes, optimization plans and test results to the customer, allowing the customer to understand the progress throughout the process, reflecting our professionalism and responsibility, and further deepening the customer's trust in us.

In addition to the challenges brought by the above two special requirements, there was a small episode during the mass supply. Due to the sudden surge in the customer's market demand, the original order volume increased significantly, and the customer required us to increase the supply volume in a short time to ensure that its production progress was not affected. At that time, our production line was already operating at full capacity, and to increase the supply volume in a short time, we faced multiple pressures such as production equipment, manpower and raw materials. However, in order to protect the customer's interests and meet the customer's needs, China Chungfo Fan immediately held an emergency meeting and formulated an emergency supply plan: on the one hand, adjust the production line layout, optimize the production process, improve production efficiency, and fully tap the potential of existing production equipment; on the other hand, temporarily deploy manpower, organize employees to work overtime, and communicate and coordinate with raw material suppliers to ensure the timely supply of raw materials; in addition, the quality control team up the whole process to ensure that the product quality was not reduced while increasing the supply volume. Through the joint efforts of all employees, we completed the production and delivery of additional orders within the time limit required by the customer, ensuring that the customer's production progress was not affected. The customer highly praised our emergency response capability and sense of responsibility, believing that we are trustworthy partners, which further consolidated the long-term cooperative relationship between the two parties.
