CORE PRINT

The projections placed on pattern to form seats in the mould for introducing dry sand cores in the mould ,are known as core -prints.

Core Print

core -prints make impressions in the form seats into which the cores may be set and thus reattained in proper position in the mould .when the reversal of a core in the mould would spoil the casting ,the prints are made of such a size and shape that would be impossible to set the core in any position except the proper one.
Core prints should be made to give the least inconvenience in moulding .the print of the core should exactly fit the core seat.the print should be of sufficient and will size and so that impression in the sand will have plenty of bearing surface and will not be crushed out of shape by the weight of the core or by the molten metal.
