Quality control

Inspection Equipment

Dimensional metrology, material verification, mechanical testing, NDT, surface measurement and pressure / leak testing are selected around the drawing and service risk.

Quality control is wider than CMM inspection

Our inspection resources cover dimensional metrology, material verification, mechanical testing, nondestructive examination, surface measurement and pressure / leak testing. The project drawing and service risk determine which methods are required.

Control area Equipment / method Typical purpose
Dimensional Hexagon CMM, Mitutoyo CMM, conventional gauges GD&T, bores, datums, position, form and final dimensions
Material identity Spectrometer, ferrite tester Chemistry / alloy identity and ferrite where specified
Mechanical properties Brinell / Rockwell hardness; tensile / impact on specified samples Verify specified property requirements on representative test samples
Surface / corrosion Roughness measurement; project-specific corrosion / passivation verification Surface condition and specified corrosion or cleanliness evidence
NDT Penetrant; ultrasonic or radiographic examination where technically suitable Detect surface or internal discontinuities according to geometry, defect type and specification
Pressure / leakage Hydrostatic and pneumatic test resources Validate finished pressure-boundary components at the required stage

Inspection planning

A useful inspection plan identifies the feature, method, stage, sampling level, acceptance criterion and required record. CMM inspection is important, but it does not replace material verification, NDT or pressure testing when those risks exist.

Supplier-qualification support

During supplier qualification, we can provide equipment lists, calibration status, applicable certificates and sample quality records.

Start with the drawing

Send the alloy, annual quantity and critical requirements.

Email is the fastest route for drawings and 3D files. The short form is available when email is inconvenient.

For the fastest drawing review, include:
  • 2D drawing / 3D file and revision
  • Material grade or service environment
  • Annual quantity or expected lot size
  • Critical tolerances, finish, inspection or pressure-test requirements

For drawings and 3D files, use direct email. info@chinaprecisionmetal.com.
