Chairman and CEO, Mr Arthur Lee established the parent company, Kolinker Industrial Equipments, Ltd. in 1983. The main strategic focus was on designing and producing quartz crystal equipment. The motto of the company is to act as a CORE of various up-to-date high technologies and to LINK these technologies to specific fields of industry: the CORE-LINKER, hence KOLINKER.

By 1989, the Group diversified into the quartz crystal manufacturing and trading and Hong Kong X’tals Ltd was formed in 1991. The global brand “HKC” has since gained wide recognition in global automotive, electronic networking and industrial/consumer electronic appliances industries. All the production plants at Zibo, Qingdao and Shenzhen in China are endowed with QS9000 and TS16949 certification.

Besides global recognition for its products, the Group has twice received industrial grand awards — “the Hong Kong Award for Industry – Machinery and Equipment Design Grand Award” (2002) for the KH6800 Automatic Final Frequency Adjustment System, and “Hong Kong Awards for Industries: Machinery and Machine Tools Design Grand Award” (2011) for the KH2000 Ion Etching System.

One of our important technical publications “Direct Impedance Method for Load Resonant Measurement of Crystal” was presented in the Piezoelectric Device Conference & Exhibition, USA in 1999. It has been recognized as the de facto standard in the quartz industry since its publication.
