I am an engineer in United States. I met sign-in-global at the Shanghai EXPO in July, 2013. They are a very professional group, they have a lot of parts get my attention, machines, all brand printheads, and also very good quality OEM parts... I bought 2 Mutoh Printhead, they are of very good quality. Definately original parts with very good price. My machine works perfectly... 

 

What’s more, they have warehouse in USA, and can help build my own website... This is really very interesting to me... I want to know more about them...
