I have a customer from USA, and we started to cooperatefromsample in September this year.  He ordered1pcs LFE944 sample only at the beginning.My customer provided detailed drawings andtechnical data at that time. Let us do it according tohis requirements. The result of test has passed about sample after two month,My customer contacted me again yesterday.  He said thathe wouldrepeat 500 orders again. But this timemy customer requested thatend cap material is made of aluminum. The sample weproduced is made of plastic. My customer said plastic frame separated during the threading, Its glued. See the photos as below: Thats why the reason he did not choose plastic this time 

 After discussion with our technical dept. We can meet his demand. Can do aluminium material and integrated. Need to open mould. And already sent proforma invoice to him. Wait payment now. He said 500pcs will be initial order. He is planning to order 500-1000pcs every two month. I sincerely hope our cooperation will be better and better.
