Core Technology and Competitiveness

Through independent research and development and technological innovation, we provide highly automated production solutions with high precision, stability, and cost advantages.

  • In-Mold Riveting Automation

    Stamping + Riveting + Inspection Integration. Sino-1 introduced Japanese technology and after years of R&D and innovation, has developed a series of products including stamping contacts, stamping wires, stamping tapping, and stamping assemblies. These products feature high precision, stability, and automation, saving labor and manufacturing costs. The company possesses independent mold R&D capabilities with short lead times and low costs.

  • In-Mold Welding Automation

    Stamping components are an industry combining capital and technology, widely adopted by European and American counterparts due to safety requirements. Product quality is more stable than riveting. Sino-1 has used imported German Böllhoff automatic welding machines for many years. With years of absorption knowledge and innovation, it has developed over 50 sets of equipment, featuring annual autonomous R&D capabilities, independent modular mass production capacity, and the ability to handle orders from international major manufacturers.

  • Composite Material Componentization (Inlay)

    Composite materials are functional materials with superior properties such as silver alloy electrical conductivity, excellent weldability, and economic pricing. This is independently developed technology by Sino-1 and has obtained national invention patents. The company has vertical integration capabilities from process formulation, silver alloy production, composite technology, to equipment manufacturing, including whole-plant output. It develops new material technologies, such as iron-copper composite bullet heads, stainless steel brake discs, and also possesses waste material purification technology!

  • Independent Production of Rolling Welding (Onlay)

    Onlay composite strip is a self-developed next-generation product based on traditional Inlay composite strip. It features simplified processes, short delivery times, high yield, and full-process automation. Currently, the equipment is only exclusively manufactured in Switzerland. Sino-1 has successfully developed multiple sets of fully automated production lines, which are now in mass production.

  • Multi-Station Fully Automatic Assembly

    A fully automated assembly system for the hardware industry, uses high-precision servo drive and pneumatic actuation technology to achieve high-speed assembly of complex hardware parts. It integrates multi-station processes such as laser welding, riveting, and automatic lock screw tightening, combined with visual positioning technology to ensure high-precision assembly. The modular design supports multi-specification product production across multiple stations. Through robotic automatic loading/unloading and integration with intelligent logistics systems, it realizes full-process unmanned operation. A special dust-proof protection structure adapts to metalworking environments, and equipped with in-line inspection modules, significantly improving production efficiency and quality stability. The system has quick changeover capability, suitable for large-scale hardware manufacturing scenarios.
