Hwashi Sink Welding Machine: Premium Strength Joints for Kitchenware Production

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

Seam welding is a kind of form permanent metal welding.When welding, welding pressure, between two welding wheel spin welding wheel drives the weldment and electricity, welding current by welding and local heating, forming successively overlapping to form a continuous weld joint and realize the permanent welding.Light reaction for casing, such as automobile, motorcycle fuel tank; Barrel, such as cans, and sheet forming artifacts, such as wheels, seam welding of muffler, radiator, etc.

Adopt 75KVA/100K medium frequency inverter DC power source. Duty cycle rate is 50% while welding output current is 26KA. The three-phase power supply, through rectified by a special inverter, is converted into 1000Hz AC voltage and then is transmitted to a medium frequency transformer so the current is rectified in order to supply DC welding current.
