Founding Story

August 2023

GELINDE Optical Co., Ltd. was officially established in Chongqing, leveraging the combined production capacity and technological advantages of three factories, the team embarked on a new journey of global market expansion.

December 2022

Invited by local investment promotion and taking advantage of the proximity to China’s second-largest optical glass manufacturer NHG, XINSHENG Optoelectronic Technology Co., Ltd. was officially established in Xiangyang, extending the capability to process infrared, far-infrared material ball lenses, and aspherical mold press preforms.

January 2022

Invited by local investment promotion, DEYI Optical Technology Co., Ltd. was officially established in Zaozhuang, Shandong Province, the team built the processing capability of ultra-high precision spheres in optical glass, custom specialty glass, ruby and sapphire, silicon nitride ceramics and zirconia ceramics…

2019

The annual production of high-precision micro ball lenses exceeds 100 million units.

2018

JIYUAN Optoelectronic Technology Co., Ltd. was officially established in Xuzhou, Jiangsu Province. This new company purchased three Japanese HTC multi-wire cutting machines, initiating full-process manufacturing and control from raw material cutting. The autonomous production in all processing steps increased the product yield rate to over 99.5%.

2017

With industry-leading product yield, Mr. Li Daxin’s team gained even bigger market recognition, especially attracting the attention of a well-known Chinese optical communication company’s TO-CAP supplier. The team increased their self-developed grinding machines to 45 sets, with an annual production of high-precision micro ball lenses over 50 million units.

2016

Based on solid material knowledge and professional mechanical design capabilities, combined with practical grinding experience, Mr. Li Daxin’s team successfully modified the first ball grinding machine, and innovated the grinding process. This significantly improved the product precision and enabled ball lot consistency control to far surpassing industry peers, with batch yield control above 98.9% and an annual production capacity exceeding 10 million units in the same year.

2015

Mr. Li Daxin’s team introduced high-precision ball lens to the market and gained recognition, achieving a monthly production capacity of 500,000 units with a product yield rate of over 95%.

2014

Mr. Daxin Li, together with his partners, started trial high-precision ball lens grinding, based on three secondhand machines (one year after graduating from Beijing University of Chemical Technology and working in the carbon fiber industry shortly) and his own Individual Household Entity was registered in the same year. The team compared their trial products with those on the market, recognized significant business opportunities, and focused on researching optical ball lens grinding.
