Expert sheet metal bending solutions for high-quality prototypes and production components. From simple bends to complex formed parts, Tuowei delivers precise metal bending services with rapid DFM review and exceptional turnaround times.
Metal bending is a core metal fabrication process that reshapes flat sheet metal into precise angles and curves by applying mechanical force, without cutting material away or changing its thickness. It is the forming step that turns a flat, laser cut blank into a functional three-dimensional part. At Tuowei Precision, our metal bending service covers everything from simple 90-degree flanges to complex multi-bend components, using advanced electric and hydraulic press brakes that deliver superior accuracy and consistent results, even on parts with tight tolerances. We bend metal in aluminum, stainless steel, carbon steel, copper, and galvanized steel, and every project includes comprehensive post-processing, so your bent parts arrive formed, finished, and ready for immediate use. Bending is one stage of our complete تصنيع الصفائح المعدنية service — most parts start as blanks from our laser cutting services (or plasma cutting for very thick plate) before they reach the press brake.
A press brake machine forms sheet metal between a punch and a die. The flat sheet is positioned against a CNC (computer numerical control) backgauge, the punch descends, and the metal is pressed into the die opening until it takes the target bend angle. Because the deformation is controlled and repeatable, a CNC press brake holds the same angle across a single prototype or a full production run. Tuowei’s press brakes are hydraulic press and electric models, programmed directly from your CAD (computer-aided design) file for fast setup and minimal variation.
Unlike tube bending, which forms hollow sections around a mandrel, or pipe bending for fluid lines, sheet metal bending folds flat parts — but the engineering principles are shared. Three factors decide whether a bent part meets its specification: the bend radius (typically at least equal to the material thickness to avoid cracking), the bend allowance and K-factor (which calculate the flat pattern length so the finished component lands on dimension), and springback (the metal’s tendency to relax after forming, which our operators compensate for by overbending slightly). Controlling these factors is how we prevent distortion and deformation, and how flat parts become accurate finished components. The best metal bending results start with a correct flat pattern: send us your CAD file or DXF and our engineers will check every bend before production.
Tuowei provides precision bending capabilities that combine advanced machinery, strict quality standards, and final inspection to handle a wide range of metal types, part sizes, and production volumes — for quality metal bending results from prototypes to large-scale production runs.

Surface finishes for bent metal parts enhance strength, durability, and appearance, making them suitable for both functional and aesthetic applications. Finishing is usually applied after forming, so the coating stays intact through the bend. Popular options from our surface finishing services تشمل:
The natural finish straight off the press brake, ideal for functional applications where a decorative finish is not critical.
Propels media such as glass beads at the surface to create a smooth, uniform matte finish.
A durable coating offering excellent resistance to wear, corrosion, and UV exposure, available in a wide range of colors.
Applies a linear, uniform grain texture, creating a satin-like finish.
Ideal for steel components, this dark, matte finish provides mild corrosion resistance while maintaining a quality appearance.

How much does a metal bending service cost?
Cost depends on the material and thickness, the number and complexity of bends, tolerances, finishing, and quantity. Because bending needs no dedicated tooling beyond standard punch and die sets, it is one of the most economical forming methods — and per-part cost falls quickly with volume. Upload your design for a free quote with DFM review within 1 day.
What tolerances can sheet metal bending hold?
Our standard bending tolerances follow ISO 2768: bend angles hold ±1 degree, and bend-to-edge or bend-to-hole dimensions hold ±0.254 mm (±0.010 in.) on a single surface. Tighter tolerances are available on many geometries — share your specification and we will confirm what is achievable before production.
What types of metal can be bent?
We bend aluminum, stainless steel, carbon steel, copper, and galvanized steel sheet and plate. From thin-gauge aluminum enclosures to heavy steel bending work, material hardness and ductility decide the minimum bend radius: softer alloys form tighter radii, while harder grades need a larger radius to avoid cracking. Our capabilities cover thicknesses up to 60 mm and bending forces up to 1,000 tons.
What design files do you need for a bending quote?
Send a 3D CAD file (STEP is preferred) or a DXF flat pattern with bend lines, material, thickness, and finish called out. If your design does not yet account for bend allowance and K-factor, our engineers will develop the flat pattern for you during the free DFM review.
How fast can bent parts be delivered?
Standard lead times start at 5 days, and many prototype orders ship in as fast as 3–5 days depending on complexity and finishing. Because cutting, bending, and finishing happen in-house, your parts avoid the delays of moving between separate metal services and suppliers.
