I spent a day in Botou City’s factories and, to be honest, the hum of sheet metal forming never gets old. The Stretching And Flanging Integrated Machine I watched was a compact workhorse—fast, surprisingly quiet, and, yes, very operator-friendly. Below is the short version of what matters if you’re comparing machines this quarter.
| Model | YT-360 |
| Barrel height | 450–550 mm |
| Barrel diameter | 360 mm |
| Plate thickness | 0.5–0.8 mm (real-world may vary with grade) |
| Flanging width | 9 mm |
| Tube diameter | 6.5–8 mm |
| Working oil pressure | 5–7 MPa |
| Control & drives | PLC: Delta; Inverter: Delta; Motor: Siemens; Main reduction motor: Taiwan Yongkun; Pneumatics: Yadeke; Intermediates: Schneider |
| Origin | Botou Industrial Zone, east side of National Highway 104, Botou City, Hebei Province |
Typical run: blanking → shallow draw (stretching) → ironing as needed → flanging → trim/deburr → QC. Materials I’ve seen on this line: SPCC, DC01, and 304 stainless (thin-gauge); aluminum 3003 is doable with careful lube. Methods use hydraulic forming with PLC sequencing; tool steels are usually SKD11 or Cr12MoV for dies. Service life? Dies ≈ 300–500k cycles before major regrind; hydraulics often surpass 20,000–30,000 h before overhaul if oil is kept clean.
Testing standards referenced onsite: ISO 12100 for safety risk assessment, IEC 60204-1 for electricals, and CE conformity to the Machinery Directive. For metals, plants typically verify incoming coils via ISO 6892-1 tensile tests; edges are checked to ISO 13715 guidance. In our quick audit, burr height measured ≤0.05 mm, flange concentricity ≤0.3 mm, and cycle time hovered around 18–22 s per barrel—pretty respectable.
Combining stretch and flange on one frame cuts handling and alignment errors. The Stretching And Flanging Integrated Machine also simplifies operator training—Delta PLC screens are clear, and Siemens drives feel overbuilt (in a good way). Many customers say scrap dropped by ≈3–5% after switching from separate stations.
| Vendor | Control stack | Lead time | After-sales | Price band | Notes |
|---|---|---|---|---|---|
| XDR (Botou) | Delta + Siemens | ≈ 35–55 days | Remote + on-site, spares stocked | Mid | Balanced cost/performance; easy PLC tweaks |
| Regional Competitor A | Mix (brands vary) | ≈ 45–70 days | Variable | Low–Mid | Good price, but documentation can lag |
| Imported Brand B | Siemens + proprietary HMI | ≈ 90–140 days | Strong, but costly | High | Excellent finish; higher TCO |
A northern paint-drum maker swapped two aging presses for one Stretching And Flanging Integrated Machine. Result after 60 days: throughput +18%, rework down to 1.2%, average energy draw ≈ 4.1 kWh per 20-unit batch (shop meter, not lab-perfect). Their line lead told me, “We stopped chasing alignment issues—operators are happier, frankly.”
CE declaration available; electricals built to IEC 60204-1; safety assessment per ISO 12100. For export, documentation packs usually include wiring diagrams, BOM, hydraulic schematics, and FAT records. Noise measured ≈ 76–78 dB(A) at 1 m (shop floor).
