Do a little bit of digging in the following areas: - Service/Support in China; How good or how bad is it? - Ease of use; can the operators harness all the features? or will you be baby-sitting them? - Access to parts/spares pricing...follows under t

Forgot details: Use a sample product that you will be running in production. Let each Equipment vendor run a test to meet your requirements. Often with each of these machines (MPM/DEK/EKRA) the key machine features are: -2D Inspection (for minimiz

Good Morning All, We have a Mydata shop. 5 lines in all. We are also using a mix of old style and Agilis feeders. The claim that you will not loose parts in loading is based on keeping the clip with the reel. This is the whole basis of the Agilis co
