Corventa measures the radius after every pass, works out how far the part is from the target and keeps bending until it is inside your tolerance. The first part is a good part.
Works on 4-roll profile benders, plate rolling machines and mandrel-less tube benders.
Springback changes with every profile, every batch and every material. So operators bend, check, adjust and bend again. Each test piece is scrap, each short series repeats the setup, and the result depends on the few people who know the machine by feel.
A standard geometric bend brings the part close to the target radius.
A patented three-point measuring head on the moving roll reads the radius the part really has, after springback.
The software calculates how far the part is from the target and sets the next roll position by itself.
Bending continues until the part is inside the tolerance you set, then stops. Every value is logged.
There is no fixed tolerance. Each job gets the precision it needs: tighter for architectural parts, faster for structural ones. The path to the target gets shorter with every part Corventa learns from.
Illustration. Corventa calculates the real number of passes for every job.
Corventa improves its values with each part and shortens the total bending time. Results are stored in the Corventa Cloud. When the same parameters come up again, on the same machine or on the other side of the world, bending starts from the best known scenario.
"First part right" is a feature your competitors can't offer, and three patents keep it that way.

Closed-loop bending control
Demos are free, need no NDA and come with no obligation.
See Corventa run on our 4-roll machine in Bursa Organized Industrial Zone, Türkiye, with your own profile. All four rolls move, and the hydraulics are built for 200 bar.
Almost any section can be bent. Send us the profile details first and we'll confirm.
Plan a visitWatch it bend over a live video link. Your engineers ask questions and see the measurements as they happen.

Corventa is a patented closed-loop bending control system for bending machine manufacturers (OEMs). A measuring head on the moving roll reads the real radius of the part, and the software calculates the remaining gap to the target and corrects the next pass automatically, until the part is inside the tolerance the user sets. It works on 4-roll profile bending machines, plate rolling machines and mandrel-less tube benders. It is developed by Corventa Bending Teknoloji A.Ş. in Bursa, Türkiye.
Corventa doesn't predict springback from tables. It measures the result. After a rough geometric bend, the part's real radius is measured on the machine, after springback has already happened. The software calculates how far the part still is from the target and bends again, repeating until the radius is inside tolerance. Each result is stored, so the next part with the same parameters starts closer to the target.
You don't have to take that risk blind. First you see it bend your own profile on our machine. Then we review your machine and control system in a feasibility step before any integration starts.
4-roll profile bending machines, plate rolling machines and mandrel-less tube bending machines. The Corventa configuration is adapted to each machine model.
Yes. The closed loop needs our measuring, control and software to work together, so the Corventa control panel is part of every installation. Your mechanics, frame and hydraulics stay as they are.
Yes. Existing machines can be retrofitted with the Corventa panel, measuring head and calibration, which turns your installed base into a new revenue stream.
As precise as the job needs. There is no fixed tolerance: the user sets it per job, and Corventa keeps bending until the part is inside it.
You do. OEMs get admin rights in the Corventa cloud panel and manage their fleet, their jobs and their data as they choose.
Yes. Corventa is protected by three patents in Türkiye (2022/008326, 2022/003965, 2022/011854). The software runs with a separate license key on every machine.
No. Demos are free and NDA-free. An NDA only comes in when we start looking at your machine for integration.
It depends on the machine type, the partnership model and the volume. Tell us about your machines and we'll send you a tailored quote.
