Guangdong Huilun Crystal Technology Co., Ltd. was established in 2002 (formerly Dongguan Huilun Dunbao Electronics Co., Ltd.). It is a national high-tech enterprise specializing in the research and development, production, and sales of new surface mount quartz crystal resonators, oscillators, and thermosensitive crystals. The company was listed on the ChiNext board of the Shenzhen Stock Exchange on May 15, 2015, with stock code 300460. The company's headquarters is located in Huangjiang Town, Dongguan City, with 500 employees. The headquarters factory covers an area of approximately 35000 square meters, while the Chongqing factory covers an area of approximately 45000 square meters. The total area of the factory is approximately 80000 square meters, and it has over a hundred internationally leading imported fully automated production lines. The company's products are widely used in various fields of the national economy and are essential basic components for modern electronic products such as consumer electronics, intelligent terminals, network equipment, industrial equipment, intelligent security, and automotive electronics.
After more than 20 years of precipitation, Huilun Crystal has become one of the leading enterprises in the domestic surface mount piezoelectric quartz crystal component industry. The company achieved mass production of small and micro resonators such as SMD2520, SMD2016, and SMD1612 in China earlier. We have established the only national level laboratory in the industry, the Piezoelectric Quartz Crystal Component Research and Development Center, and have undertaken national, provincial, and municipal level scientific and technological projects multiple times. Among them, "Surface mount components for frequency control and selection in ultra small and high-precision wireless communication (SMD3225, 26MHz)" are listed as national key new products; The key technology research and industrialization of precision quartz crystal temperature compensation oscillator (TCXO) has been selected as a key project in Guangdong Province.
In the future, the company will continue to focus on the research and development, production, and sales of surface mount piezoelectric quartz crystal components, striving to become a leading global supplier of "frequency control and selection" piezoelectric quartz crystal components, and expanding the development and application of other intelligent electronic products. The company adheres to the principle of "quality first, reputation first, customer first, and enthusiastic service", actively strives for progress, and extensively communicates and exchanges with domestic and foreign customers and partners to jointly develop and create the future!
