        Since its establishment in 2003, Guangzhou Zhileng Technology Co., Ltd. has been deeply rooted in Guangzhou, China—a globally renowned core hub of the automotive industry. As one of the world's most thriving bases for the production and sales of whole vehicles and auto parts, Guangzhou has laid a solid foundation for the company to deepen its presence in the field of automotive air-conditioning compressors, thanks to its well-developed industrial ecosystem, efficient and convenient supply chain system, and global market reach. It has also provided the enterprise with unique industrial advantages for its subsequent large-scale development.       

        As an integrated industrial chain service provider focusing on the field of automotive air-conditioning compressors, the company has, over the years, concentrated deeply on the structure and working principles of compressors from world-leading brands such as Denso (Japan), Sanden, Valeo, Zexel, Calsonic Kansei, Panasonic, and Mitsubishi. To accurately master core technologies, it has not only invested substantial funds and human resources in conducting product dissection analysis, performance simulation testing, and reliability verification, but also, through continuous technical research and development, built a mature team of technical elites with both industry experience and innovative capabilities. Additionally, the company has established a data management system covering the entire product lifecycle of design, production, testing and after-sales service, providing scientific support for technological iteration and quality control.

        In the manufacturing process, the company also demonstrates strong capabilities: from the precision molding of housing die-casting and accurate machining of blanks to the fine grinding of high-precision components, a standardized and normalized production system has been established for every process to ensure product consistency and stability. Meanwhile, relying on a comprehensive range of professional testing and inspection equipment for components, coupled with a strict whole-machine performance verification process, each compressor must undergo thousands of hours of durability operation tests, ultimately meeting the OEM original factory matching standards — whether in the texture presentation of product appearance or the assembly accuracy of internal components, it is highly consistent with the original factory. It is precisely this "pursuit of excellence" in technical accumulation and "strict control" in production standards that has enabled the company to form an irreproducible technical competitiveness in the industry.

        The Japanese NASIDE brand compressors under the company serve as the core embodiment of its technology and quality. Boasting three core advantages—"reliable quality, stable operation, and ultra-low noise"—products of this brand have quickly built a premium reputation in the global automotive aftermarket. Furthermore, guided by the product philosophy of "originating from original factories and outperforming them," the brand has broken the industry's inherent perception of "replica parts" and won widespread acclaim from domestic and international customers. To further enhance the customer experience, the company has established a professional and efficient after-sales service system: from pre-sales technical consultation and in-sales installation guidance to after-sales fault response and maintenance support, a dedicated team is assigned to follow up promptly and resolve various issues customers encounter during product use quickly. This dual adherence to "quality and service" has enabled the products to be successfully sold to dozens of countries and regions, including Europe, the United States, the Middle East, Africa, and Southeast Asia, earning deep trust and long-term recognition from global customers.

        For years, "Originating from original factories and outperforming them" has been not only the company’s product philosophy, but also the core value that runs through its development. The company has always been driven by technological iteration and focused on process optimization, continuously enhancing the durability and adaptability of its products, and is committed to providing users in the global automotive aftermarket with higher-quality and more reliable automotive air-conditioning compressor solutions. Today, standing at the new starting point of the automotive industry’s transformation toward intelligence and green development, the company, with the enterprising spirit of "spreading its wings to strive for greater heights" (literally "spreading its wings to fight the sky"), sincerely extends a cooperation invitation to elites from all walks of life in the industry. It is willing to join hands with partners to deeply explore the market with a higher industry positioning and longer-term development goals. In the process of promoting the high-quality development of the auto parts industry, the company will help the "Made in China Dream" step onto the center of the world stage and shine with the strength of Chinese enterprises!
