Multi-stage insert molding method |
摘要 |
A multi-stage method of insert molding is described including the steps of: providing a vertically movable first mold member with a cavity formed therein; providing a second mold member having a substantially flat upper molding surface; providing a third mold member having an upper end with a cavity formed therein; positioning an insert directly on the flat upper molding surface of the second mold member; positioning the first mold member with respect to the second mold member so that the cavity of the first mold member receives the insert; injecting a first flowable plastic material into the cavity in the first mold member to partially encapsulate the insert; allowing the first flowable plastic material to cool and solidify, thereby creating a first stage molding; removing the first mold member and the second stage molding from the second mold member; positioning the first mold member with respect to the third mold member so that the first stage molding registers with the cavity of the third mold member; injecting a second flowable plastic material into the cavity of the third mold member; allowing the second plastic material to cool and solidify to form a second stage molding; and ejecting the second stage molding from the cavities in the first and third mold members.
