ABSTRACT:
An improved hot tip (40) for forming a thermoplastic body having a mold cavity (42) and a gate portion (44) has an elongated body member (46) and a channel (48) passing axially through the body member (46). The channel (48) has an inlet end (51) and outlet end (52) for passing a molten material, such as an amorphous resin, therethrough. The body member (46) has a necked-down portion (54) surrounding the outlet end (52) of the channel (48). The necked down portion (54) is configured to permit the outlet end (52) of the channel (48) to proximately contact the gate portion (44) of the mold cavity (42) resulting in a formed body having vestigeless gate.
