OEM Supply

When the machine send to your company . You can arrange your engineer to our company to learn operate the machine . We will arrange our engineer to teach your company engineer to operate the whole machine . You only need to pay your engineer to China the air tickets fee , hotel fee and food , It is ok !

We also can arrange our engineer to your country . You need to pay the air tickets fee , hotel fee ,food .and per day USD50 salary .
