All types of custom design Screw And Barrel components, to meet different customer requirements.
Since the injection molding screw tip is always under the higher wear and corrosion working condition than screw body. Per customer`s request, we will also provide the screw tip with different material from screw body,
like SKD61 or bimetallic (alloy) coating.
