PROCESS CONTROL

Quality Control

Key quality control processes are shown below.

In-process inspectionDimensional and geometric checks during production

Dimensional inspection of a finished industrial blade — **Final inspection**Critical dimensions checked against the agreed requirements

01 / REVIEW

Technical and material review

Confirmed drawings or sample records, material requirements and acceptance items are retained. Raw-material batches, heat-treatment batches, production work orders, inspection records and reports can be traced together; these records are normally retained for 10 years and checked for repeat orders.

02 / IN-PROCESS

In-process inspection

Perform in-process inspection against the confirmed process. Changes to the drawing, material, heat treatment or key process are confirmed with the customer before implementation.

03 / FINAL

Final inspection

Verify the agreed material, dimensions, mounting interfaces and cutting-edge requirements. For new custom projects, sample approval can be recorded by signed sample, inspection report, approved drawing or email, as agreed with the customer.

04 / RELEASE

Batch release

Release each batch against the acceptance criteria, retain the inspection records and provide an inspection report with the shipment.

CONTROLLED CHARACTERISTICS

Inspection Scope

Key inspection items are shown below.

Material verificationMaterial checked with a handheld analyser

Operator using optical measurement equipment to inspect blade geometry — **Dimensional and geometric inspection**Optical measurement of blade profile and dimensions

01 / MATERIAL

Material composition verification

Spectrometry or handheld X-ray fluorescence analysis is selected where applicable to the material route and project requirements.

SPECTROLAB spectrometer and VCA handheld XRF spectrometer

02 / HARDNESS

Hardness and metallographic inspection

Vickers hardness, Rockwell hardness or metallographic inspection is applied according to the material, heat-treatment route and controlled requirements.

Mitutoyo MVK-H100, ZHR-8150LK and NIKON metallographic microscope
