Advantages of using resin sand casting machine bed casting
Aug 28, 2017

1 resin sand rigidity is good, pouring the initial high sand strength This is the condition of the use of cast iron solidification process of graphitization expansion, effectively eliminate shrinkage, shrinkage defects, to achieve gray cast iron, ductile iron pieces of the riser, no riser casting The

2 real casting production in the use of polystyrene foam pattern application Fufang resin from the hard sand shape. When the molten metal is poured into the mold, the foam is rapidly gasified and burned under the action of the high temperature metal liquid. The molten metal replaces the position occupied by the original foam, and solidifies it into the same type of casting as the mold shape.

3 In fact, Lost Foam Casting for large-scale production of single-piece or small-volume car cover, machine bed and other large mold than the traditional sand has a great advantage, it not only eliminates the cost of expensive wood, and easy to operate, Shorten the production cycle, improve the production efficiency, with high dimensional accuracy, processing margin is small, the surface quality is good and other advantages; In addition, casting machine tool processing has good wear resistance and shock performance and good process performance.
