While incoming QC guards inferior components from going into production lines,outgoing QC reassures that only qualified products leave our factory. 100% quality checking is carried out at our offline W-Inspection line to guarantee zero-defect items. Every Production process is equipped with full-time quality inspector. They have to inspect all of the parts' dimension and accuracy according to national standard or international standard to ensure all of the parts are okay to go to next process. And the inspector should calculate the quantity of each bundle according to the packing list to make sure the quantity is right ,packing properly and the surface is smooth.
