Haolun Environmental Protection Technology

Guangdong Haolun Environmental Protection Technology Co., Ltd. was founded in 2006 and is a high-tech enterprise integrating R&D, production, sales, and service. It specializes in manufacturing: a series of industrial laundry chemical auxiliaries, a series of brightening additives for electroplating, an environmentally friendly trivalent chromium passivation series, and a series of nano-sealants. It is one of the fastest-growing suppliers of high-quality electroplating chemicals in China.


Hao Lun believes that electroplating processes must embrace an environmentally friendly, energy‑efficient, and highly productive path of sustainable development to meet the demands of modern industrial production. The company adopts a business model of “international‑oriented R&D and domestic‑focused manufacturing and sales,” while also introducing a collaborative development approach with renowned laboratories in Europe and North America. As a result, it has developed a series of eco‑friendly electroplating additives—free of cyanide, lead, cadmium, and phosphorus, and based on trivalent chromium—and obtained SGS environmental certification. Since its inception, Hao Lun has consistently adhered to and met the requirements of the ISO 9001 quality management system, the ISO 14001 environmental management system, and the OHSAS 18001 occupational health and safety management system. Consequently, our high‑quality products have earned the recognition and trust of customers worldwide, including such prominent clients as Huawei, GAC Group, BYD, Changan Automobile, and General Electric.


The company’s product sales are centered on the Pearl River Delta and the Yangtze River Delta, with multiple sales and service outlets established nationwide to provide customers with efficient, prompt technical support, help resolve challenging electroplating issues, and earn a strong reputation within the industry.


The company operates a state-of-the-art laboratory equipped with cutting-edge production equipment and testing instruments, supported by a research team comprising numerous seasoned professors and senior engineers, continuously developing new technologies and products for the industry.


“Technology leadership, service first” is the business philosophy that Haolun has consistently upheld. While providing customers with high‑efficiency, high‑quality, technologically advanced products, Haolun’s seasoned engineers also deliver efficient, attentive services. These services encompass factory design, process optimization, raw material compatibility, plating bath analysis, and post‑sales technical support. Our goal is to do everything in our power to ensure that every issue our customers encounter during production is addressed promptly and effectively.
