Resin sand casting

Use customized wooden core boxes and wooden patterns with pouring system as moulding patterns,use resin sand to do moulding process. Verify the shape and dimensions of the customized wooden patterns before moulding, then brush paint the parting agent on the wooden patterns' working surface and air drying, then use furan resin sand do the moulding process (make sand moulds and sand cores), after the resin sand is solidified and sand moulds are separated from the wooden patterns, apply refractory paint on cavity surface and sand core surface and baking, then complete the assembly of sand cores and sand moulds,at last pouring the molten iron into the cavity through gating system, then the castings are obtained after cooling, solidification and sand knockout.
