Custom cast iron parts are mechanical parts made by pouring molten cast iron (such as gray cast iron HT200, ductile iron QT500, etc.) into a mold designed according to customer needs, cooling, sand cleaning and post-processing. This process can flexibly produce parts with complex shapes, high wear resistance and good shock absorption performance, such as machine tool bases, gearboxes, hydraulic valve bodies, etc. After casting, shot blasting, machining and other processes ensure dimensional accuracy and surface quality, meet the strength, heat resistance and cost requirements of different industrial fields, and are widely used in industries such as automobiles, agricultural machinery, construction and heavy machinery. https://www.simis-group.com/iron-casting-foundry
