Conventional Bending
Conventional bending uses manually set press brakes, folding machines and benders for simple bends and low quantities. It is economical for one-offs, repairs, simple brackets and long straight folds where CNC programming isn't needed.
What it is
An operator sets stops and angles manually and checks parts with gauges. For simple single or double bends in small quantities, this is quick and cost-effective.
Hand benders and pipe/section benders are also used for bars, flats and tubes on site-style and repair work.
Typical applications
- One-off brackets and angles
- Repair and maintenance parts
- Simple covers and flashings
- Flat bar and strip bending
- Prototype bending trials
Suitable materials
- CRCA and HR mild steel
- Galvanised steel (GI/GP)
- Stainless steel (304, 316)
- Aluminium (5052, 6061)
- Flat bars and strips
Points to consider
- For multi-bend parts or batches, CNC bending gives better consistency.
- Provide a clear sketch with inside or outside dimensions marked.
- Allow a slightly looser tolerance than CNC work.
Frequently asked questions
When is conventional bending better than CNC?
For simple bends in very small quantities, where CNC setup and programming would cost more than it saves.
Can flat bars be bent?
Yes. Flat bars, strips and light sections are bent on conventional benders.
How accurate is conventional bending?
Typically around ±1° on angle, adequate for many brackets and covers.
