160kVA Stainless Steel Sink Welding Machine with Medium-Frequency Inverter and CNC 3-Axis Servo Control for Industrial Kitchen Sink Production

Designed to provide consistent, high-quality welds for kitchen sink manufacturing applications, this specialized automated solution delivers flawless, high-strength seams for stainless steel sink bowls—critical components in kitchen utensil manufacturing.

At its core is advanced seam welding technology utilizing high-frequency resistance welding (HFW) paired with a servo-driven welding wheel system. This ensures uniform heat distribution along curved or straight seams, creating airtight, leakproof joints with a smooth post-weld surface finish (Ra ≤ 0.8μm)—eliminating the need for 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).

1. Operator places sink bowl onto fixture on moving table
2. Table automatically moves to welding position
3. Welding roller follows pre-programmed path, creating continuous sealed seam
4. Table returns to loading position for finished sink removal
5. Next cycle begins immediately with near-zero idle time
