MOULDING RUBBER PLUGS TO ELECTRIC CORDS

Technique

INJECTION MOULDING IS A PROCESS WHERE MOLTEN PLASTIC OR RUBBER IS FORCED INTO A DIE TO PRODUCE THE DESIRED SHAPE. THIS DIE SET WAS USED TO MOULD PLUGS ON THE END OF ELECTRIC CORD SETS AND IS ESTIMATED TO HAVE PRODUCED OVER 3 MILLION DURING ITS 20 YEAR LIFESPAN. IT IS OBSOLETE NOW BECAUSE OF A RE-DESIGN OF THE PLUGS. IN USE THE OPERATOR ASSEMBLED THE CORDS IN ONE HALF OF THE DIE, THEN LOWERED THE PRESS ARM WITH THE TOP HALF OF THE DIE ATTACHED TO IT. PLASTIC WAS FORCED INTO THE OPENING AT THE SIDE AND WHILE IT WAS BEING CURVED THE OPERATOR POSITIONED ANOTHER SET OF CORDS ON THE OTHER SIDE OF THE DIE. WHEN THE ARM WAS RELEASED AND MOVED ACROSS TO THE NEW CORDS, A STRIPPER PLATE KNOCKED THE CURVED CORD SET FREE AND THE OPERATION WAS REPEATED ON THE OTHER SIDE. MOST MODERN CORD SET PLUGS ARE OF PVC RATHER THAN RUBBER. IF THE DIE TEMPERATURE VARIES UPWARDS BY MORE THAN 5%, THIS MATERIAL RELEASES HYDROCHOLORIC ACID. THUS THE SURFACE OF THE DIE IN CONTACT WITH THE EFFECTS OF CORROSION.
