Main  Description: 

 Phenolic resin coated sand shell molding production line is mainly used to produce high-quality castings: such as automobile cylinder blocks, cylinder heads, intake manifolds, various pipe fittings, pump bodies and other complex castings.

The sand mold produced by the shell molding process has the advantages of high strength, good air permeability, and good sand collapsibility. The surface of the castings produced is smoother, has high geometric and dimensional accuracy, reduces or does not require mechanical processing, and shortens the production cycle. Saving metal materials and reducing costs can significantly reduce casting defects, improve the inherent quality of castings, and reduce the rejection rate of castings.
