Question 1

What files should I upload for sheet metal bending?

Accepted Answer

Upload a 2D drawing (PDF) with formed dimensions and bend notes, plus a flat pattern (DXF) or 3D model. Include material/gauge, inside radius targets (or tooling notes), and CTQ callouts like flange-to-flange and hole-to-bend.

Question 2

How do you control bend angles and springback?

Accepted Answer

Angle control is achieved through tooling selection, brake setup, and springback compensation based on alloy/temper and bend geometry. A first-article check is used to tune angles before running the batch.

Question 3

Can you form short flanges or tight radii?

Accepted Answer

Short flanges and tight radii depend on thickness, material, and tooling. We review feasibility using minimum flange and inside radius guidelines and may recommend bend reliefs or alternate design strategies.

Question 4

What dimensions should be toleranced on bent parts?

Accepted Answer

Tolerance the dimensions that drive assembly: angles, flange lengths, flange-to-flange, and hole-to-bend. Avoid over-tolerancing every bend; it increases cost without improving function. Reference our ***ISO 2768 chart***(/resources/charts/iso-2768-tolerance-chart), ***tap drill calculator***(/resources/tools/drill-tap-chart), and ***drill bit size chart***(/resources/charts/drill-bit-size-chart) when specifying holes and threads.

Question 5

Do you support finishing after bending?

Accepted Answer

Yes, when specified. Common options include deburr/edge break, powder coating, zinc plating, anodizing (aluminum), and passivation (stainless). Finish selection should match corrosion and cosmetic needs.

Question 6

What drives cost the most in sheet metal bending?

Accepted Answer

Primary drivers include material/gauge, number of bends, bend length, complexity of bend sequencing, tight angle/formed tolerances, cosmetic protection requirements, and any secondary operations or hardware insertion.
