Sango Metal Bending Workshop
Metal bending transforms flat sheets into 3D shapes through precision force application, using advanced machinery to enforce bends at designated angles. Before bending, the flat sheet is prepared using high-precision fiber laser cutting.
At Sango, our process leverages high-tonnage equipment capable of exerting up to 1,000 tons to handle sheet lengths up to 7,200mm. Each bend is executed with exact punch and die molds ranging from R0.5 to R50, ensuring accuracy with tolerances down to ±0.1mm.


Sheet Metal Bending Capabilities
Metal Bending Materials
Aluminum Sheet Bending
Lightweight and corrosion-resistant, aluminum is ideal for aerospace brackets and electronics chassis. We form Aluminum 5052-H32 (excellent formability with zero cracking), 5083, and 6061-T4/T6 (with appropriate bend radii).

Metal Bending Surface Finishes
Enhance the corrosion resistance, electrical conductivity, and aesthetic appearance of bent metal parts.

As Formed / As Machined
Clean deburred sheet with natural mill finish and precise bend lines.

Type II Anodizing
Corrosion and wear-resistant oxide coating available in black, clear, blue, and gold.

Type III Hard Anodizing
Heavy-duty hardcoat providing 50+ HRC surface hardness and superior dielectric insulation.

Alodine / Chem Film
MIL-DTL-5541 chromate conversion maintaining electrical conductivity and corrosion resistance.

Sand / Bead Blasting
Uniform satin-matte textured surface that conceals tool marks and scratches.

Polishing & Buffing
High-gloss mirror and satin finishes for visible consumer-facing panels.

Brushed Satin Finish
Unidirectional grain texture ideal for stainless steel kitchen and appliance panels.

Electropolishing
Electrochemical passivation creating an ultra-smooth, micro-clean surface for medical uses.

Powder Coating
Durable thermoset polymer coating in any standard RAL color with matte or textured finish.

Electroplating (Zinc/Nickel)
Thin protective metallic barrier preventing galvanic corrosion and enhancing solderability.

Vibratory Tumbling
Mass finishing to round sharp sheared edges and achieve a smooth, uniform radius.

Heat Treatment & Annealing
Stress relieving post-bend to eliminate work hardening and restore maximum ductility.
Key Manufacturing Advantages
Cost & Assembly Efficiency
Eliminates multiple welds, fasteners, and manual joints, reducing assembly hours and bill-of-materials complexity.
Enhanced Structural Strength
Continuous bent corners work-harden the metal along the bend axis, increasing stiffness without adding weight.
High Dimensional Repeatability
CNC backgauges and laser crowning ensure tight angular accuracy (±0.5°) across thousands of production units.
Aesthetic Appeal
Seamless rounded transitions, flush seams, and clean industrial contours create premium finished products.
