1. Stamping process => Continues punching 1 CV hard tooling and Heat process tooling cost investment abut 100K baht. For this process is yield loss and we have very high material cost!
2. Outsource process Laser cutting => Yield is OK and high process cost and from start we can use this out source and next may we can investment for this machine. The outsource cost tomorrow I will go to test laser for this part and ask for cost down, And NG rate will be on supplier not ARC.
3. Normal die cutting process => Yield OK but after cut may edge of FG will be not in good condition.
