Description
Stainless Steel Sink Welding Machine
Product Overview

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.

Key Application

Addressing 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 in industrial sink production.

Core Technology

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).

Key Advantages
CNC 3-Axis Servo Control
  • Japan Mitsubishi servo motors control X, Y, and A-axis movements
  • Input coordinate data and welding current for automatic execution
  • 95 welding programs storable for quick model switching
  • Suitable for welding at any angle, including complex R-corners
Medium-Frequency Inverter (MFDC) Seam Welding
  • 30%+ more energy-efficient than conventional AC
  • Fast DC current rise, stable output, minimal spatter
  • Overlapping weld nuggets create continuous, airtight seams
  • Current control accuracy ±1% for consistent quality
Large Copper Flat Table Electrode
  • Specially designed large flat copper platform
  • Ensures consistent welding current distribution
  • Minimizes heat distortion on thin stainless steel
  • Custom-designed fixtures for each sink model
360° Rotating Welding Wheel
  • Servo-controlled A-axis enables 360° rotation
  • Seamlessly welds R-corners, straight edges, and curves
  • No manual repositioning required
  • Uniform, aesthetically pleasing welding seams
Automatic Moving Welding Table
  • Synchronized operation of welding electrodes and table
  • X-axis travel: ≥2,500 mm for oversized products
  • Y-axis travel: ≥750 mm for full depth coverage
  • Smooth gear-rack transmission for precise positioning
Water-Cooled System
  • Water-cooled transformer, SCR, and electrode assembly
  • Enables extended continuous operation
  • Stable weld quality throughout long production runs
  • Low maintenance requirements, long service life
Workflow Process
  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
