Company profile
DSG CO., LTD., also presented under the DASHING name, was established in 1983 and began by manufacturing power distribution boxes before expanding its product range. In 1998 it added a production line for precision sheet metal used by a semiconductor-equipment company, marking an early semiconductor-equipment manufacturing milestone. The company achieved ISO 9001:2000 certification in 2002 and began component manufacturing for an international TFT-LCD company in 2010. Its Yongkang factory was established in 2011, and in 2012 it became the first Taiwanese company to pass powder-coating certification by an international equipment organization. In 2014 it obtained OHSAS 18001:2007 and ISO 14001:2008 certifications, followed in 2015 by a production line for semiconductor-equipment frame casings and spray painting. The DASHING Industrial Park factory was completed in 2017, CBJ TECH was established in 2019 and a new WEIJU machining factory was completed in 2020. The company converted to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications in 2020 and implemented MES and WMS systems in the same year. Its quality materials list AWS-certified welding inspectors and welders, including 30 AWS carbon-steel welders. DSG states that it became a main supplier to leading semiconductor companies in 2015 and supplies internationally known semiconductor-equipment and panel-equipment manufacturers. The group operates an independent logistics system intended to protect customer confidential information and product safety. Its factories are located within roughly 10 to 20 minutes of one another, supporting rapid response across integrated production processes. The engineering factory includes a Demmeler 3D platform, TT-C-490 pretreatment, semiconductor-customer-certified spray painting, automated shot peening and cleanroom assembly facilities. The Anping factory provides laser cutting, CNC turret punching, CNC hydraulic press-brake processing, precision sheet metal processing and cleanroom assembly. The WEIJU factory uses DMG five-axis machine tools, AWEA gantry-type five-face machinery and COORD3 coordinate-measuring equipment, while CBJ focuses on surface treatment, laboratory testing and cleanroom inspection or assembly. The group describes its business as integrated manufacturing, combining sheet metal, equipment fabrication, coating, surface treatment, chamber and precision-component machining.
Exhibits
For semiconductor and panel equipment, DSG defines manufacturing processes to each customer’s specifications and quality requirements with the objective of achieving high finished-product precision. Its integrated process scope includes laser cutting, bending and forming, welding and assembly and surface treatment. For each finished-product material, the company selects corresponding processing machinery together with design programs and specific cutting tools to improve efficiency and avoid contamination between dissimilar materials. Bending and forming are simulated with professional software before production so tools and coefficients can be confirmed and packet settings completed to keep deviations within drawing tolerances. Welding processes follow applicable American Welding Society specifications through Pre-PQR, Pre-WPS, PQR, official WPS and WQR steps, with external testing and CWI inspector certification. Surface-treatment capability includes an ultra-pure cleaning process for semiconductor parts and processes aligned with international regulations and United States military standards. The group also offers large-scale powder coating, which it describes as having better adhesion and weather resistance than generic liquid coating, with coating processes certified by semiconductor and TFT-LCD customers. Machining equipment includes a DMG MORI DMU200 GANTRY five-axis CNC machine for large, high-precision components. The equipment list also includes high-precision coordinate-measuring machinery used to verify that product dimensions meet customer requirements. A robotic-arm welding machine provides six-axis vertical multi-joint welding with modular programming and fixed welding parameters. The Demmeler 3D welding platform is used for welding and measurement, supporting positioning and dimensional control during fabrication. The COORD3 UNIVERSAL bridge coordinate-measuring machine has a worktable load capacity of 4000kg and measurement accuracy conforming to ISO 10360-2. That measuring system uses a RENISHAW PH10M scanning-head module and automatic probe switching, together with temperature and humidity control and temperature compensation to reduce thermal-deformation error. DSG lists chamber processing, bending and forming, welding service and surface treatment as core manufacturing services and uses smart equipment and automation to increase manufacturing capacity. Its integrated manufacturing approach therefore combines customer-specific process design, material-specific machine selection, precision forming, qualified welding, clean processing, surface treatment and dimensional verification. For semiconductor-equipment and panel-equipment applications, these processes are used to produce high-precision finished parts while controlling contamination risks between different material systems.
