Exhibits
For automotive and motorcycle programs, Dao Siang supplies custom precision components where precision, durability and production consistency are required. For bicycles, it provides scalable custom machining for components where lightweight design, structural strength and appearance quality are emphasized. For AI server components, the company offers high-precision custom machining for structural accuracy, thermal performance, assembly stability and reliable mass production. Communication components are machined for structural accuracy, signal stability and production consistency, while medical components are supplied for applications requiring high precision, safety and consistent quality. Robotic components are supported with custom precision machining for precise fit, smooth motion and wear resistance, and industrial components can be machined across multiple materials for strength, corrosion resistance and long-duty cycles. Optical and electronic components can combine precision machining with cleanroom cleaning and packaging where tight tolerances and cleanliness control are required. The solution process begins with feasibility studies covering design, materials, machining methods and mass-production feasibility to reduce risk and improve efficiency. Low-volume prototyping is available to validate design and functionality before production, helping move projects from concept toward mass production. Material-sourcing support draws on machining experience with metals and engineering plastics so material selection can be matched to each application. Integrated machining combines Swiss-type CNC with multi-process manufacturing in a one-stop precision-machining flow intended to simplify supply-chain coordination and control lead time and quality. ISO Class 7 cleanroom services cover component cleaning, inspection and packaging, providing controlled handling for applications with cleanliness requirements. Customized packaging is available to protect product integrity during domestic and international transportation, and the company works across both manufacturing and logistics stages rather than stopping at machining. The company presents standardized process control, quality assurance, smart manufacturing and production-capacity management as parts of its core manufacturing framework. Together, these capabilities support one-stop CNC precision machining and OEM production for global clients across automotive, bicycle, AI server, communications, medical, robotics, industrial, optical and electronic applications. Cleanroom support is not limited to washing: the ISO Class 7 service explicitly combines cleaning, inspection and packaging for components that require controlled cleanliness. For optical and electronic parts, that cleanroom flow can follow precision machining, giving one supplier responsibility for machining, controlled cleaning and protected packaging. Global OEM work also includes liquid-cooling connectors in addition to bicycles, automotive, electronics, telecommunications, optics, medical devices and robotics.
Company profile
Dao Siang Industrial Co., Ltd. was founded in 1986 in Taichung, Taiwan and manufactures precision metal components, with CNC turn-mill composite machining as a core specialization. Dao Siang is certified under the ISO 9001 quality management system and provides OEM manufacturing for bicycles, automotive products, electronics, fiber-optic connectors, pneumatic components and precision motor shafts. Its manufacturing focus is high-precision, multi-feature components that require tight tolerances, integrated processes and consistent quality during mass production. To support changing product designs, the company invests in machining equipment, precision inspection systems and integrated secondary processes including surface treatment, heat treatment, grinding, blasting, plating and laser processing. ERP, MES, SPC and MSA systems are used to create a data-driven and fully traceable manufacturing environment intended to stabilize processes, quality and delivery performance. Dao Siang describes quality as something embedded through design, manufacturing and management rather than limited to final inspection, and presents integrity, professionalism and long-term partnership as operating principles. Its global one-stop CNC precision-machining and OEM services address industries including bicycles, automotive, electronics, telecommunications, optics, medical devices, liquid-cooling connectors and robotic components. Since the introduction of Swiss-type CNC machining in 1993, the company has continued to build its precision-manufacturing route around high-precision turning-milling and integrated processing. Its high-precision CNC turning-milling operations are based in Daya District, Taichung. Integrated secondary processing allows surface treatment, heat treatment, grinding, blasting, plating and laser processing to be coordinated with primary CNC work inside a one-stop manufacturing solution. This process integration is intended to reduce production risk and coordination complexity for customers as designs move from machining into secondary treatment and final handling. Traceability through ERP, MES, SPC and MSA supports process data, quality consistency and dependable delivery while linking manufacturing records across the production flow.
