ABSTRACT:
Apparatus and methods for molding a part with at least one passage at least partially therethrough. Generally, the method includes injecting a molding material into a mold cavity having at least one pin disposed therein to form the passage. In preferred implementations, the injection of molding material can cause displacement of a movable support for the pin and allow molding material to surround the pin to form the passage. Additionally, or alternatively, preferred implementations can include the movable support, when extended into the mold cavity, guiding and ensuring proper alignment of a free end of the pin for capture within a recess defined by at least one portion of the mold. Still yet other preferred implementations can additionally or alternatively include the extended movable support straightening out the pin and/or inhibiting deflection of the pin, which can be caused by the injected molded material.
