That uninhibited circumstances of aerofluxus have not been existing in both upper and lower earholes inside the cavity of cold core box of an integrated core of Model 17 coupler resulting in low degree of packing of sand core has been mainly introduced.Defects have been found in present technologies of core setting and superimposed core while both the quality and rate of ifnal products of sand core have been highly increased with intelligent use of core vent hence the pouring and castings quality in the late have been given security.
