Quality Control
Quality is built in at every process step, not just inspected at the end. Our five-stage quality control pipeline operates under ISO 9001, ISO 14001 and IATF 16949:2016 certified systems, covering every order from raw material to shipment.
Incoming Quality Control
Every material batch is verified before release to production, so only qualified raw materials enter our stamping, CNC and tooling lines.
- Chemical composition verification for each material lot
- Mechanical property testing: hardness, tensile and yield strength
- Dimensional and surface checks on raw stock: thickness, flatness, defects
- Mill certificates and RoHS / REACH compliance documents reviewed, then batch-labeled
In-Process Quality Control
Real-time monitoring during production with automated inspection systems keeps every process step within tolerance, from first article to last piece.
- First-article inspection and approval before mass production
- In-die monitoring at each station of progressive stamping
- CAM-verified tool paths and on-machine probing for CNC milling and turning
- Scheduled patrol inspections with recorded dimensional data
Final Quality Control
Full dimensional verification and functional testing before shipment confirm every part matches your drawings and specifications.
- Dimensional inspection against customer drawings, holding ±0.005mm to ±0.02mm on CNC features
- Functional and cosmetic inspection: fit, form and surface defects
- Surface treatment verification: plating thickness and powder coating adhesion
- Batch inspection reports generated before packing
Outgoing Quality Control
A final audit before dispatch ensures the right parts, the right documentation and protective packaging leave our factory together.
- Pre-shipment sampling audit against the approved batch record
- Protective packaging, labeling and carton condition verification
- Dimensional inspection reports included with every shipment
- Shipping documents matched to order and batch numbers
Quality Exception & Traceability
When exceptions occur, batch-level traceability lets us contain, analyze and correct issues quickly — and feed the lessons back into the process.
- Batch-level traceability from raw material lot to finished shipment
- Non-conforming parts isolated and documented immediately
- Root cause analysis with corrective and preventive actions tracked to closure
- Customer feedback looped into process improvement reviews
Quality Control FAQ
Common purchasing questions about our five-stage inspection pipeline. For project-specific requirements, talk to our quality team.
Every shipment includes dimensional inspection reports. Batch inspection reports are generated before packing, and during outgoing inspection (OQC) shipping documents are matched to your order and batch numbers.
Incoming quality control (IQC) checks every material batch before release to production: chemical composition verification, mechanical property testing for hardness, tensile and yield strength, dimensional and surface checks on raw stock, and review of mill certificates plus RoHS / REACH compliance documents. Qualified batches are then labeled for traceability.
In-process quality control (IPQC) starts with first-article inspection and approval before mass production, then continues with in-die monitoring at each station of progressive stamping, CAM-verified tool paths and on-machine probing for CNC milling and turning, and scheduled patrol inspections with recorded dimensional data.
Yes. Final quality control (FQC) performs dimensional inspection against customer drawings, holding ±0.005mm to ±0.02mm on CNC features, plus functional and cosmetic inspection for fit, form and surface defects, and surface treatment verification including plating thickness and powder coating adhesion.
Non-conforming parts are isolated and documented immediately. Batch-level traceability from raw material lot to finished shipment lets us contain the issue, perform root cause analysis and track corrective and preventive actions to closure, with lessons fed back into process improvement reviews.
The five-stage pipeline operates under ISO 9001:2015, ISO 14001:2015 and IATF 16949:2016 certified systems, audited annually, with RoHS and REACH compliance for material documentation.
