Overview

Inspection and Testing at Jianheng Metal

Inspection is planned at the stages where a problem is still cheap to fix, not only at final inspection. Composition is verified before pouring, dimensions on the first article and across the batch, and mechanical properties on test bars from the heat.

Where the drawing calls for non destructive testing we agree the method and the acceptance criteria in writing before production, so that there is no argument about the result at inspection.

FAQ

Questions About Inspection and Testing

What inspection reports can you supply?

Chemical composition from spectrometer analysis, mechanical properties from tensile, impact and hardness testing, dimensional reports including CMM and 3D scan data, and non destructive test reports where the drawing requires them.

How large a part can you measure?

The gantry CMM has a measurement range up to 10 000 mm on the longest coordinate axis, with a travel range of 3 m by 10 m by 2 m.

Which non destructive methods do you use?

Ultrasonic testing for internal defects, magnetic particle inspection for surface and near surface defects, X-ray for internal structure, and penetrant testing with either coloured or fluorescent dye.

Can you inspect to our own standard?

Yes. Send the inspection standard and the acceptance criteria with the drawing. We agree them in writing before production so the result is not disputed later.

Do you inspect during production or only at the end?

Both. Important production stages are inspected, likely problems are forecast and solutions agreed in advance, and a final inspection is run to the agreed standard and requirements.
