Abstract

PURPOSE:To realize a constant speed potting process regardless of the position a metal mold assumes in a metal mold lineup by a method wherein switching circuits are incorporated in the transfer molds and control the flow of resin into the said molds. CONSTITUTION:A constant current power source, resistors R0, R1, R2, R3, R4, and R5, and switches turned off and on responding to the conditions of resin in metal molds, constitute a monitoring system. With a metal mold 1 filled with resin, the circuit including the resistor R1 closes, thereby reducing to a 1/2 the current through the resistor R0. With metal molds 1-3 are filled with resin, the circuits including the resistors R1-R3 close, reducing to a 1/4 the current through the resistor R0. With a controlling unit operating on the current received through the resistor R0 contained in a transfer mold forming machine or externally connected thereto, constant speed potting can be effected lasting until the last metal mold is filled up with resin.
