WIRE Quality Assurance
Incoming Quality Control
According to New Best IQC management, the QC team experiment on all income materials from suppliers. Qualified and approved materials will be accepted and loaded into the warehouse.

In Process Quality Control
According to New Best PQC management, the QC tem inspect all semi-finished wire. Only qualified and approved semi-finished wire will be continued production.

Process Flow of uncertain or disqualified defect wire
We won’t let the defect wire products continue its production or even be delivered to customers.
When surface defect, incorrect wire dimension, wire label (material label or matching label) missing issues are founded by production team, they will hang “Uncertain” label on the wire immediately. The uncertain wire products will be moved to dis-qualified area.
QC team will go to dis-qualified area to check and inspect those uncertain wire products. If QC people confirm those uncertain wire products are dis-qualified, they will hand “Dis-qualified” label on the wire and issue dis-qualified notice by system.
Dis-qualified notice will be issued to and judged by QC supervisor. Once the QC supervisor completes the judgement, the Dis-qualified notice will be issued to responsible unit. The responsible unit needs to find out the root causes and bring out solutions to improve the same issue happen again in the future.

NO
QC team judged the wire product and informed production people that the product is qualified.
Production people will remove the “Uncertain” label from the wire.
Tracking System
From wire rod raw materials, semi-finished wires to finished wire products, they all have unique number and label. All production flow and testing results can be traced and checked by ERP system.
