Now, we focus on developing lost form casting for wear-resistant castings and heat-resistant parts for mining. Now product includes manganese steel hammer and alloy steels liner containing chromium, nickel, and molybdenum. We constantly redesign shredder components to accommodate the specific needs of individual customers. Lost-form casting is much better than traditional method fro environmental protection. Also it can permit strict dimension and tolerance and very good surface quality for casting parts. According to the experience of customer, this point will save you both time and trouble during the assembling.
