Claim 1
Independent Claim

A METHOD FOR FORMING SOLID POLYMERIC SEALS COMPRISING THE STEPS OF PLACING A RING SHAPED PLASTIC BLANK ON A FIRST DIE MEMBER, PLACING A SECOND THE MEMBER OVER SAID FIRST DIE MEMBER, HOLDING SAID BLANK BETWEEN SAID DIE MEMBERS WITH A PREDETERMINED HOLDING FORCE WHICH EXERTS A FIRST PRESSURE ON SAID BLANK, DISCHARGING AN EXPOLOSIVE FORCE OF PREDETERMINED MAGNITUDE AGAINST A SURFACE OF SAID DIE MEMBER TO CREATE A SECOND PRESSURE WHICH IS TRANSLATED THROUGH SAID FIRST DIE MEMBER TO A SURFACE OF SAID BLANK, SAID SURFACE OF SAID BLANK BEING OF SMALLER AREA THAN SAID SURFACE OF SAID FIRST DIE MEMBER, WHEREBY SAID TRANSLATED SECOND PRESSURE IS MULTIPLIED AND ADDED TO SAID FIRST PRESSURE TO FORM A THIRD PRESSURE SUFFICIENT IN MAGNITUDE TO DESTROY THE ELASTIC MEMORY OF SAID BLANK, AND THEREBY EXPLOSIVELY SETTING SAID BLANK IN CONFORMANCE WITH SAID DIE MEMBERS TO FORM A PLASTIC SEAL.
