CNC Bending Service
Are you looking for a way to bend metal with perfect accuracy? CNC bending might be just what you need! At Istar Machining, we use computer-controlled machines to bend metal parts into exact shapes. Our high-tech process gives you better parts, saves material, and works faster than old-fashioned hand bending.
- Control exactly how much the metal bends
- Make the same bend over and over without mistakes
- Create complex 3D shapes that would be hard to make by hand
- Work with many different types of metal

Frequently Asked Question
CNC bending means using computers to control how metal gets bent. The “CNC” part stands for “Computer Numerical Control.” This technology lets us bend metal into complex shapes with very small mistakes – as little as 0.05mm off!
The cost depends on the material, complexity, and quantity. We offer per-bend pricing with minimum orders starting at 50 units.
Yes! We use special anti-ovalization tooling to keep square and rectangular tubes from getting distorted.
We work with DXF, STEP, and IGES files. Our team can also help convert your drawings if needed.
For most materials, we can bend down to 1.5 times the material thickness. For example, a 2mm thick sheet can be bent with a 3mm inside radius.
Small prototype runs can be done in 3-5 days. Larger production runs are scheduled based on complexity and quantity.
