Abstract
A fastener includes a fastener body with a peripheral surface that is configured to be received in a mold assembly. The body is divided into an encased portion and an exposed portion. The encased portion is configured to be surrounded by molding material. The exposed portion is configured to be void of molding material. A crush rib extends along at least a portion of the peripheral surface at an interface between the encased portion and the exposed portion.
Claims20
A fastener comprising:
- a fastener body with a peripheral surface configured to be received in a mold assembly, the body being divided into an encased portion and an exposed portion, the encased portion configured to be surrounded by molding material and the exposed portion configured to be void of molding material;
- and
- a crush rib extending along at least a portion of the body at an interface between the encased portion and the exposed portion, the crush rib being configured to be sealably engaged by a mold assembly during a molding process.
A fastener comprising:
- a fastener body comprising a peripheral surface, the peripheral surface having at least a first load bearing surface and an opposite second load bearing surface;
- and
- a first crush rib disposed on the peripheral surface, the first crush rib is configured to deform such that a seal is formed between the fastener body and a mold assembly.
A method of injection molding utilizing a mold assembly, the method comprising:
- inserting a fastener into the mold assembly, the fastener having a fastener body, the fastener body having a peripheral surface configured to be received and securely retained in the mold assembly, the body being divided into an encased portion and an exposed portion;
- closing the mold assembly with sufficient force to at least partially deform a crush rib formed on the body;
- and
- injecting a molding material into the mold assembly such that the molding material substantially surrounds the encased portion and such that the crush rib prevents the molding material from contacting the exposed portion.
