About HKC
Leading Manufacturer in Frequency Products
Our quartz crystals & oscillators are widely for applications in telecommunications, computing, consumer electronics, IoT, wearables, 5G, UAVS, automotive & autonomous driving.
The parent company of the Kolinker Group, Kolinker Industrial Equipments Limited (KIE), was established in 1983 to specialize in equipment for the quartz crystal industry. 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
Building upon our engineering roots, the Group expanded into quartz crystal manufacturing by 1989, leading to the formation of Hong Kong X’tals Ltd (HKC) in 1991. Today, the global “HKC” brand is widely recognized across automotive, electronic networking, industrial, and consumer electronics markets worldwide. To power its next phase of growth, the Group launched a massive expansion project between 2015 and 2017, constructing a new mega-facility in Huizhou to consolidate multiple factories into a single, unified high-capacity production hub.
Besides global recognition for its products, the Group has twice received industrial grand awards: the KH6800 Automatic Final Frequency Adjustment System (2002) and the KH2000 Ion Etching System (2011). In 2019, the Group was also honored with the Hong Kong Awards for Industries: Equipment and Machinery Design Award for its advanced GNSS Disciplined Oscillator. Furthermore, our seminal technical publication, “Direct Impedance Method for Load Resonant Measurement of Crystal” presented at a US conference in 1999, remains recognized as the de facto standard in the quartz industry.
In 1999, our manufacturing plant was the first PRC crystal factory accredited with QS9000 (now IATF 19649). Cementing our dedication to absolute quality, the testing center of our Huizhou plant officially obtained the prestigious CNAS Laboratory Accreditation Certificate in 2024. This rigorous accreditation highlights our world-class testing standards and commitment to delivering high quality, high-reliability components.
Driven by a future-focused R&D pipeline, HKC has continuously anticipated and adapted to next-generation technologies. With over 30 years of dedicated service to the global automotive industry, including pioneering the production of crystals for safety-critical airbag applications since 1999, we supply a comprehensive portfolio of reliable automotive-grade components, ranging from high-demand safety systems to less demanding applications. As technology evolves, we have significantly expanded our capacity for ultra-small ceramic SMD crystals and high-frequency oscillators engineered for wireless communication systems, broadcast base stations and autonomous driving. Expanding our footprint further, we now offer specialized, high-reliability components tailored for Drones, Unmanned Aerial Vehicles (UAVs) and the rapidly growing AI industry.
