Two-color injection molding machine for plastic

Features:
   The clamping Unit adopts two sets of hydraulic independent ejector system to expand scope of application and flexibility.
   There is a 180to-and Cfro rotary drive on the moving platen. It can place two moulds to produce products of two different colors.
   Rotate the cooling water connecting device of platen mould. The needed cooling water can be conveniently connected through rotating axis to avoid winding and interference of cooling water pipe.
   Both two ejection units adopt new-type single cylinder ejection construction. Ejection and charging operate independently, so several compound ejection can work together. 
   Fine hydraulic circuit design can reduce the pressure of oil pipes, so the hydraulic control is more accurate. 
   Two independent proportional pressure & flow control circuits are used to control and drive two sets of injection devices and two sets of hydraulic ejector systems. 
   The product is molded and formed in one time, therefore, the degree of contraction is reduced to the minimum and the appearance quality is much improved.
