What is Sheet Metal Bending ?

TonZa Making|Bending

Sheet metal bending is a process in which force is applied to a flat sheet of metal to deform it into a specific shape. The metal is bent around a straight axis, changing its shape without affecting its thickness. This process is fundamental in creating a wide variety of components used in numerous industries, ranging from automotive to aerospace.

Why Choose Ours Sheet Metal Bending Service?

Capabilities of Sheet Metal Bending Services

We offer premium sheet metal bending services, delivering high-precision, expertly finished components at highly competitive prices.

Design Guidelines

Optimize your designs for manufacturability with our expert guidelines and feedback, ensuring the best results in injection molding service

Minimum Bend Radius

1. Use a minimum bend radius equal to or greater than the material thickness to prevent cracking.

2. For brittle materials (like aluminum or stainless steel), a larger radius may be needed.

Bend Orientation

Always bend in the direction of the grain (rolling direction) for increased ductility and reduced risk of cracking.

Bend Allowance and K-Factor

1. Account for material stretching during bending by using the correct bend allowance.

2. Use the K-factor (typically between 0.3–0.5) to calculate accurate flat patterns.

Relief Cuts

Add relief notches or slots near bends to prevent tearing or deformation, especially for interior bends or adjacent features.

Hole and Slot Placement

Keep holes, slots, and other cutouts at least 2x the material thickness away from any bend line to avoid distortion.

Flange Length

The minimum flange length should be at least 4x the material thickness or match the tooling requirements of the press brake.

Consistent Bend Direction

Design parts with bends in the same direction to reduce handling and setup time in production.

Tolerances

Consider looser tolerances for complex bends and tighter ones for critical features—bending can introduce variation.

Materials for Sheet Metal Bending

Overmolding technology represents a breakthrough in multi-material integrated manufacturing, offering a wide range of material pairing possibilities to meet diverse industrial needs.

FAQ

We provide high-precision plastic overmolding services that ensure seamless bonding, enhanced durability, and a perfect fit for complex multi-material parts.

We work with a wide range of materials including aluminum, stainless steel, mild steel, galvanized steel, copper, brass, and titanium.

Our equipment handles sheet metal thicknesses up to 10mm, depending on the material type and bend requirements.

We offer tight bending tolerances as low as ±0.2mm, and even tighter with CNC-controlled bending for critical parts.

Yes, our engineering team can review your drawings and suggest improvements to bend radius, material choice, and manufacturability.

Absolutely. We support one-off prototypes and small-batch runs, helping you validate designs before moving to mass production.

Springback is the material's tendency to return to its original shape after bending. We compensate by adjusting the bend angle based on material properties.

Yes, we accept STEP, IGES, DXF, and other common CAD formats for accurate quoting and production.

We provide sheet metal bending solutions for automotive, aerospace, electronics, industrial machinery, construction, and more.

Yes, we offer finishing options such as powder coating, anodizing, zinc plating, polishing, and brushing based on your needs.

Lead times vary by project size, but we typically deliver prototypes within 3–5 days and production orders in 7–15 business days.
