Robust quality management system aiming at “No material mix and No nonconforming items”

Complete traceability and process control

Our reliable quality results from strict process control that is in accordance with ISO9001, ranging from the placing of orders and receipt of materials through to the shipping of finished products. We supply materials and products under heat number control and in-house lot control to ensure complete traceability. Furthermore, we conduct PMI tests (simplified chemical composition tests) on all material after receiving and before shipping to prevent material mix from entering or leaving the place.
