Main parts, especially those easy to wear out, strictly follow the international standards, reliable and durable. Screen is a consumable part, easiest to wear out. Generally, the screen is made of Q195 cold rolled steel plate, without heat treatment or other process, which makes the screen very weak. Our screen has most advanced technology of mechanical processing, apart from the popular cold stamping, we also do Nitriding heat treatment and electroplating by Ni-Cr alloy, which make the screen quite stronger than other type, and give it a longer work life.
