Product Description

Heavy-Duty Joint Welding Machine for Kitchen Utensils | Hwashi Sink Welder

High-Strength Joints for Kitchen Utensil Manufacturing

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.

Application

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.

Heavy-Duty Performance Features

For kitchen utensil manufacturers, heavy-duty joints aren't just a requirement—they're the foundation of product durability and customer trust. The Hwashi Sink Welder is engineered to deliver industrial-grade reliability, precision, and efficiency, specifically tailored to the unique demands of welding sinks, cookware, and food-grade kitchen tools.

Robust Weld Strength for Long-Lasting Kitchenware

At the core of this machine is its ability to create heavy-duty joints that withstand the harshest kitchen conditions. It integrates a medium frequency inverter power supply system and precise heat control technology, ensuring deep, uniform weld penetration across food-grade stainless steel and high-strength alloys.

Weld joints achieve a tensile strength of up to 580MPa, exceeding industry standards for both residential and commercial kitchenware
The minimized heat-affected zone reduces material deformation by over 70%, preserving structural integrity
Corrosion-resistant welds pass 500-hour salt spray tests, ideal for moisture-exposed products

Automated Precision for Consistent Quality

Manual welding often leads to inconsistent joints, defects, and rework—costly setbacks for manufacturing lines. The Hwashi Sink Welder eliminates these pain points with intelligent automation and precise control systems.

Equipped with Mitsubishi PLC control system and three-axis servo motor linkage for automated welding track calibration
Built-in adaptive tracking technology automatically identifies product shapes and sizes for uniform weld quality
Defect rates drop to less than 1%, reducing rework costs and material waste

Efficiency & Versatility for Any Production Scale

From small-batch custom workshops to large-scale manufacturing facilities, this machine adapts to your workflow while boosting productivity.

High-speed welding delivers up to 4000 pieces per 8-hour shift, cutting cycle times by 30-40%
Database of 5000+ preset parameters allows quick changeovers (as fast as 3 minutes) between product types
Flat platform design minimizes post-weld grinding and polishing needs

Durable Build for Industrial-Grade Reliability

Engineered for heavy-duty manufacturing environments, the Hwashi Sink Welder is built to perform consistently over years of operation.

Robust frame and high-quality components withstand continuous use, reducing downtime
Advanced water cooling system ensures stable performance during long shifts
Compatible with 380V industrial power supplies and easy to integrate into existing production lines
