Quality control at KECMT
A press brake is judged by the parts it makes, so the only meaningful factory test is a bend test on real material. This page describes what we check, when, and what evidence you get — the same process we would want to see if we were buying.
The inspection sequence
- Incoming material: steel plate and section checked against grade certificates; hydraulic and electrical components checked against supplier documentation before they enter assembly.
- In-process geometry: frame squareness and bed flatness checked at assembly, while corrections are still cheap. After welding and stress relief, the frame is re-checked before machining.
- Machined surfaces: bed and ram guideways checked for flatness and finish — the surfaces the tooling clamps against.
- Hydraulic system: pressure testing at rated load, leak inspection at every fitting and seal, cylinder sync verification, and oil cleanliness verification before the system is commissioned.
- Electrical and control: wiring inspection against drawings, safety circuit function tests including guarding interlocks, and control function verification on every axis.
- Dry run: full stroke cycles at no load to check smoothness, noise and sync.
- Loaded test bends: real material at your specified tonnage, angle measured at several stations along the bed, backgauge repeatability measured by repeated positioning.
- Final inspection: the whole sequence signed off against the order specification, with the inspection record compiled for the documentation pack.
What the test bends actually prove
Tonnage, sync and crowning only show their true behaviour under load. A test bend at your working tonnage, measured along the bed, is the closest thing to a preview of the parts you will make. That is why the loaded test is the last gate before packing — and why the measurements go into the file rather than into a verbal “it tested fine.”
The documentation you receive
- Inspection and test record for your serial number, including test-bend measurements.
- Packing list matched to the physical crate.
- Operating and maintenance manual, electrical drawings, hydraulic schematic.
- Material and component certificates on request.
- CE declaration of conformity and technical file for CE-marked machines — see certifications.
- Photo or video report of your specific machine before it leaves the factory.
What we ask of buyers
Acceptance discipline on your side matters as much as factory inspection on ours: run theacceptance checklist on delivery day, on your material, at your tonnage, before final payment. A supplier confident in their process will have no objection to that sequence — and a supplier who objects has told you something.
Where this sits in the company
The factory tour page shows the physical layout the process runs in, the about page covers the company behind it, and the service page describes what happens after the machine arrives.
Frequently asked questions
What is tested before a machine ships?
The full sequence on this page: dimensional checks on the frame and bed, hydraulic pressure and leak testing, electrical safety checks, a dry run and then loaded test bends in real material, angle verification across the bed, backgauge repeatability measurement, and a final inspection against the order specification.
Do I get test documentation with the machine?
Yes — the inspection record, test-bend measurements, hydraulic and electrical test results, and the packing list all travel with the machine. For CE-marked machines the declaration of conformity and technical file are included; see the <a href='/certifications/'>certifications page</a>.
Can I inspect the machine myself before shipment?
Yes, and we encourage it for anything non-standard. Many buyers send a third-party inspector, and we support that. For standard machines a photo and video report of your specific serial number is the usual substitute — ask for it, it is included in the documentation pack.
What accuracy is verified, and how?
Angle consistency across the bed at your working tonnage, measured on test coupons at several stations along the length, plus backgauge repeatability measured by repeated positioning to the same target. Published accuracy figures are one thing; a measured record on your serial number is another.
What happens if a machine fails inspection?
It does not ship. The fault is rectified and the full test sequence is repeated — a machine that passed before the repair is not assumed to pass after it. That is the point of running the sequence at the end, not in the middle.
Do you use certified materials?
Steel and hydraulic components come with mill and supplier certificates, and the material certificates are part of the machine file. Buyers in regulated industries can request the certificates for their specific build — ask before ordering so they are compiled into the documentation pack.
