Today in the region of the Middle East, customer demand for anodizing profiles has considerably increased compared to other surface finishes. Since there is a high volume of switch-over from other finishes to anodizing finish, the quality demand towards surface quality of anodized profiles that are free from any surface defects such as weld/web lines and streak lines has increased substantially. The "APQP" (Advance Product Quality Planning) team was formed, in order to resolve these quality issues, which are very demanding from customers. The scope of the work covers the following subjects: 1) Relocation of webs/ribs from the die design aspects; 2) Reduction of webs/ribs in the die design; 3) Increase in welding chamber; 4) New die design concepts to overcome dead metal in the die to avoid streak lines; 5) Die design simulation prior to manufacture for the proposed die design, and comparison of actual extruded profiles and results.
