Core Technology of Hydraulic Kitchen Sink Production Lines

Hydraulic kitchen sink production lines utilize frame-type hydraulic presses as the core power unit, with nominal pressure systems ranging from 800 to 2500 tons. Integrated with precision progressive dies, these lines achieve high-efficiency output of 1.2 pieces per minute. Designed for processing 0.8-1.5mm thick 304/316 stainless steel sheets, they complete the entire manufacturing process — blanking, drawing, hole flanging, and edge rolling — through four-station continuous stamping, achieving contour accuracy within ±0.15mm.

The centralized hydraulic station incorporates a 25m³/min constant-temperature cooling system, maintaining oil temperature at 45±3°C during continuous operation. This extends seal life to over 18 months. Finished sinks pass 5000 impact tests (GB/T 228-2010, equivalent to ISO 6892-1) without deformation.

Fully Automated Process Control

Six-axis robotic arms enable automatic sheet feeding, while laser positioning systems achieve alignment accuracy of ±0.05mm. The drawing station employs nitrogen spring cushioning technology to control material flow velocity between 0.8-1.2m/s, limiting wall thinning to ≤8% for deep-drawn sinks (180-250mm depth). Flanging operations feature infrared real-time monitoring with automatic thermal deformation compensation of 0.1-0.3mm.

The surface treatment unit integrates six-head polishing equipment capable of switching between mirror finishes (Ra 0.4μm) and brushed finishes (180-400 grit). An IoT data platform continuously collects 32 parameters, including pressure and temperature, predicting mold maintenance cycles with ±8 hours of accuracy.

Energy Efficiency and Flexible Production

An energy recovery system converts hydraulic braking energy into electricity, feeding it back to the grid and reducing consumption by over 23%. The modular design enables rapid changeovers between single-bowl, double-bowl, and irregular sinks within ≤45 minutes. Soundproof enclosures reduce noise to below 75 dB(A), while fully enclosed cutting fluid circulation ensures zero wastewater discharge.

CE/PED-certified production lines accommodate custom sink manufacturing, supporting minimum orders of 50 units and specialized structures, including artistic basins over 300mm deep and tiered double bowls.
