Product Overview
CNC bending parts are components formed by deforming sheet or strip metal to a specified angle and radius. The challenge is not making the bend, it is making the same bend a hundred thousand times, because springback varies with material batch, thickness and grain direction.
We produce bent components on presses from 20 to 200 tons with progressive and secondary tooling, and on CNC bending equipment for fabricated sheet metal work.
Key Benefits
Repeatable Angles
Springback compensated in the tool so angles hold across the run rather than drifting.
Strength From Geometry
A formed flange stiffens a part without adding material or a welded rib.
Cost Effective Forming
Bending replaces machining or welding on many bracket type components.
Integrated Operations
Bending combined with punching and blanking in a single progressive tool.
Application Scenarios and Who It Is For
- Brackets, clips and mounting components
- Enclosure and chassis panels
- Automotive and appliance components
- Structural stiffeners and profiles
- Hardware and furniture components
If your application is not listed, send the drawing anyway. Most of our work arrives as a part nobody else wanted to quote.

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
What angular tolerance can you hold?
+/-1 degree as standard on stamped bent parts. Tighter callouts should be discussed at quotation, because they may require a different tooling approach.
Does bend direction relative to grain matter?
Yes. Bending across the grain reduces cracking risk on tight radii. If your flat pattern is fixed, tell us and we will advise on radius.
Minimum bend radius?
It depends on material and thickness. Send the drawing and we will confirm whether the specified radius is achievable in your chosen material.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
