    High-Strength Joints for Kitchen Utensil Manufacturing Hwashi Sink Welding Machine


    APPLICATION

    Hwashi Stainless Steel Kitchen Utensil Sink Bowl Seam Welding Machine is a specialized automated solution engineered to deliver flawless, high-strength seams for stainless steel sink bowls—critical components in kitchen utensil manufacturing. Designed to address the unique challenges of welding thin-gauge stainless steel (0.8-2mm thickness), this machine combines precision engineering with intelligent control to redefine seam quality and production efficiency.

    At its core is the advanced seam welding technology, which utilizes high-frequency resistance welding (HFW) paired with a servo-driven welding wheel system. This ensures uniform heat distribution along the sink bowl’s curved or straight seams, creating airtight, leakproof joints with a smooth, post-weld surface finish (Ra ≤ 0.8μm)—eliminating the need for time-consuming manual grinding or polishing. The machine’s adaptive current control adjusts welding parameters in real time based on material variations (304/316 stainless steel) and seam length, guaranteeing consistent weld strength (shear strength ≥ 300MPa) that meets food-grade safety standards (FDA, LFGB).

    Tailored for sink bowl geometries, the machine features a customizable clamping fixture with 360° rotational capability, accommodating various sink designs—from single-bowl to double-bowl configurations, deep or shallow profiles, and even sinks with integrated drain grooves. The fixture’s precision positioning (±0.05mm repeatability) ensures seamless alignment of sink components before welding, minimizing gaps that could lead to weak points or leakage.

    DESCRIPTION


    CNC 3 Axis Control Stainless Steel Kitchen Sink Seam Welding Machine is a method that uses a pair of roller electrodes instead of the cylindrical electrodes of spot welding, and the welded workpiece moves between the rollers to produce a sealed weld with a molten core overlapping each other to weld the workpiece together.

    Adopt medium frequency inverter power source of welding and large flat platform of locating method. Use the servo motor to drive X axis (locating mould) and Y axis (welding electrode) to operate under the preset procedure of PLC data. According to the stored position of welding spot, the welding product will be located inside the mould and moves horizontally along the X direction. The welding electrode will be designed to move vertically along the Y direction. The welding electrode is able to conduct 360° of rotation under the control of servo motor so it is suitable for welding different angles of products. Suitable for welding the sink within the range of 1600x700x300mm. (customized)

    FEATURE

    1. Adopt intelligent microcomputer single piece controller which achieve pure digital setting. Online computer programming, LED digital display, stable performance, convenient modification of the program online.


    2. Adopt intelligent microcomputer control welding system. When the voltage fluctuates, it will compensate the welding current automatically to ensure the stability of welding.


    3. Adopt digital circuit control; select the components from famous factories in the world to ensure the equipment could operate steadily in the long run.


    4. Adopt from West Germany, IXYS and IR silicon controlled from United States. High precision, long operating life, achieve high stability control of the magnitude of current.


    5. The transmission tile axis adopts the latest mercury conductive technology from abroad. State-of –the-art technology with good performance in transmission and conductivity.


    6. Welding roll wheel adopts the alloy copper material from Japan. High rigidity, good conductivity.


    7. The transformer adopts the high pure silicon steel sheet from Japan, good performance in magnet and electricity conductivity. Low consumption of electricity. Stronger and more stable power.


    8. Welding mold and the connection of the whole machine uses the mosaic connection. Easy to be assembled and disassembled.


    9. AC pulse, secondary rectifying and three-phase medium frequency type of welding power source are available.
