Stainless Steel Sheet Bending

🔹Mainstream Material Processing:
We handle a wide range of commonly used stainless steel grades such as 304 / 1.4301, 316 / 1.4404, and 430 / 1.4016, with thicknesses ranging from 0.5 mm to 20 mm. This covers over 95% of bending needs across industries including kitchenware, sheet metal fabrication, and architectural cladding.

🔹Specialty Material Solutions:
For high-alloy grades such as 904L / 1.4539 (high-nickel-moly corrosion-resistant steel) and 316L / 1.4404 (extra-low carbon stainless steel), we implement preheating (100–150°C) combined with segmental forming techniques. This prevents cold cracking and intergranular corrosion-especially critical in chemical processing and marine applications.

🔹Performance Data:

Material utilization rate: ≥ 98%

Bending yield for specialty steels: up to 95% (industry average: 85%)

Versatile Machine Fleet:
Our facility is equipped with a complete range of machines including:

🔹20–800 ton CNC electric press brakes (±0.1° precision)

🔹Hydraulic bending machines (for thick plates ≥10 mm)

🔹5-axis CNC bending centers for complex shapes, curved profiles, and multi-angle forming.
We achieve minimum bending radii down to R = 0.5t (e.g., 2 mm plate → R = 1 mm).

Industry-Leading Accuracy:

🔹Angle tolerance: ±0.1° (standard) / ±0.05° (high-precision)

🔹Dimensional tolerance: ±0.2 mm (t ≤ 3 mm) / ±0.5 mm (t > 3 mm)

🔹Surface finish: Ra ≤ 0.8 μm (mirror finish, no marks post-bending, superior to industry Ra ≤ 1.6 μm)

Case Study:
🔹A client from the medical device sector ordered custom 316L stainless steel bent parts. After triple-angle correction, the deviation was held within 0.08°, enabling direct ISO 10993 biocompatibility compliance.

🔹Mark-Free Bending Technology:
We use rubber-padded dies and full PE film protection, combined with food-grade water-based lubricants (ideal for 304/316). This ensures no press marks or surface scratches-critical for applications in kitchenware, sanitary products, and architectural façades.

🔹Post-Bending Clean Treatment:
Optional acid passivation (removes residual oils) and ultrasonic cleaning are available for sectors such as food machinery and pharmaceutical equipment, meeting NAS 1638 Class 6 surface cleanliness.

🔹Comparison Advantage:
While conventional surface defect rates reach up to 5%, GNEE's optimized bending process reduces this to 1.2%, cutting rework costs by 70%.
