Dear Hongliang
I have talked with Lawrence and Christophe yesterday. Regarding this special case, we prefer offer Guhring who is integrator, 8% of the value of the inserts by tools. Insert or tool body.
Since we can not test new "WAK15" until mid of July, and it may need one month. Then assume the test result is good, we need another 8-10 weeks to deliver the new insert. Totally, it is estimated we need to supply "WKP25S" for 4 month, which means around 2000pcs, which also means RMB12,500 of free tools by net price we well to Guhring.
However, we need to develop new solution for this operation anyhow. Even we manage to keep the same price, we only have 10% margin on insert which is very very low.
@Lawrence and Christophe
Please correct me if I put something wrong or anything missed.
