Some of the performance index sand will cause cast iron products appear stoma defects. By analyzing the reasons, take a series of measures to change sand properties of the green sand control related performance parameters, can effectively avoid defects occurring.

    Qualified molten iron and qualified mould is a stable qualified chilled cast iron camshafts blank two prerequisite. Our company mainly produces chilled cast iron camshafts and cold shock ductile iron camshaft, past product modeling all use hot core box, sand adopts coated sand. By the end of 2005, our company has introduced from abroad 3 tide mould sand production line, start learning use tide mould sand production cold shock camshaft blank.
In early 2006, my company pre-launch a six cylinder machine camshaft, material for cold shock ductile iron, the properties of product conforms to the drawing of the customer ?
