| High Light | automatic ironing board rack production line ，unmanned ironing board welding machine ，patented clamping welding system | ||
The Automatic Ironing Board Rack Production Line by Hwashi Technology is a fully automated manufacturing system engineered for high-volume production of ironing board frames and X-type leg assemblies. The production line achieves uncrewed operation across the entire process—from raw tube feeding, punching, and bending through multi-point combination welding to finished product unloading—eliminating manual intervention between process steps and ensuring consistent product quality at industrial scale.
Designed around Hwashi's proprietary resistance welding expertise, the line integrates servo-driven feeding mechanisms, precision bending units, and multi-head welding stations with intelligent PLC control. The patented clamping and positioning system ensures accurate tube alignment before welding current is applied—parts are securely held in position before the electrode energizes, preventing misalignment, spatter, and cold joints. This "clamp-first, weld-second" logic guarantees every joint meets structural and safety requirements without operator adjustment.
The modular line architecture allows customization of station configuration, welding head count, and fixture tooling to accommodate different ironing board designs—from compact tabletop models to full-size floor-standing units with X-frame legs. With cycle times optimized for continuous shift production, this line delivers the throughput and quality consistency that large appliance manufacturers and OEM suppliers demand.
The production line achieves true end-to-end automation: automatic tube feeding → punching → bending → combination welding → product unloading. Operators are only required for periodic material replenishment and quality inspection, reducing direct labor from 4-6 workers per shift to 1-2 monitoring personnel. This translates to significant labor cost savings and eliminates human-induced quality variation.
Hwashi's proprietary clamping mechanism (Patent No. CN202511755556.6) ensures workpieces are precisely located and firmly held before welding current is applied. The system features:
This eliminates common defects such as missed welds, offset joints, and inconsistent penetration that plague semi-automatic operations.
Multiple welding heads operate simultaneously to complete all joint connections in a single cycle. For a typical ironing board X-frame, this means both the top frame corners and the leg pivot joints are welded at once—reducing cycle time by 60-70% compared to sequential single-point welding. Each welding head features independently adjustable current, time, and pressure parameters for optimal results at each joint location.
High-precision CNC servo bending units deliver consistent bend angles and radii across thousands of production cycles. The bending parameters are stored as part of the product recipe, enabling instant changeover between different ironing board designs with zero manual recalibration.
For customers requiring the highest weld quality, the line can be equipped with MFDC (medium-frequency DC) power supplies instead of conventional AC systems:
The line supports rapid switching between different ironing board specifications—varying frame widths, leg geometries, and tube diameters—through stored welding programs and quick-change fixture modules. Typical changeover time is under 30 minutes, enabling economical production of multiple SKUs on a single line.
For customers requiring the highest weld quality, the line can be equipped with MFDC (medium-frequency DC) power supplies instead of conventional AC systems:
