Resin Sand Casting Capabilities and Processes

Resin sand casting provides amazing benefits for manufacturers who are looking to make complex parts in smaller production runs using cost effective methods One of the main benefits is that resin sand casting creates a very smooth mold surface that is strong and solid The reason is because of the sand s collapsibility when the mold compresses while solidifying So there are fewer casting
