HFJ inspection tools
HFJ In-Process Quality Check
- Incoming Materials Check
Normally, in this step, we would require material certicidation from material supplier, then inspect length/diameter/width/thickness and surface situation.
We would send some pieces of raw material to professional agency to assay material constitution, if customer has particular requiments.
- In-Process Quality Check
1) Self-inspection: In machining process, operators inspect critical dimensions & appearance at certain ratio.
E.g. will check some parts’ thread fitting at 1:2 ratio.
2) Process inspection: PQC will do once per hour inspection for certain amount according to different parts.
- Final Product Quality Check
1) Appearance: 100% inspect for parts with special requirements on surface.
2) Dimension: spot-check certain amount according to batch quantity and drawing details.
