zhoushan bimetallic extruder barrel

Specifications



1. Bimetallic Barrel for extruder;

2. Notably span the barrel life time;

3. Four types of alloys to be selected






Advantages of bimetallic barrel





· Double or even triple the llife time of a barrel by changing a nitrided steel to a bimetallic one


· Lower wear resulting in higher process stability


· Combination of wear and corrosion resistance


· Based on the processed plastics, the correct wear protection system is chosen
