Stopper Pipe for Aluminum introduction

High density and abrasion resistance, it is most suitable material used for low pressure die casting. The stopper pipe has the most favorable properties of protectiveness, impermeability and excellent precision.

The life time of the stopper pipe can be used for many years if keeping regular maintenance.Otherwise, incorrect operation and less attention to a maintenance will reduce the life time.
