Abstract

PURPOSE:To efficiently form the product having high accuracy by inserting plural pins into a metal plate forming plural holes by machining and pouring low melting point metal into a mold setting faced pattern plates in the mold. CONSTITUTION:The pins 5 are inserted into the holes boring by photo-etching, laser working and the other machining, on the upper pattern plate 3 and the lower pattern plate 4. The molten metal 21 is poured into cavity from a gate 19 through a cylinder 20. By this method, the porous precision product having good dimensional accuracy can be surely formed at good efficiency.
