Abstract
A method for molding a connector boot over a connector of a wire harness comprises positioning the connector of the wire harness into a mold cavity of a mold. A resin mixture is de-aerated to provide a de-aerated resin mixture including a synthetic resin and a hardener. The de-aerated resin mixture is injected into the mold cavity to gradually fill the mold cavity from bottom to top. The injected de-aerated resin mixture is then allowed to harden to form the connector boot around the connector of the wire harness under isothermal conditions. Once cured, the connector boot is demolded.

A method for molding a connector boot over a connector of a wire harness, the method comprising:
- positioning the connector of the wire harness into a mold cavity of a mold, the mold cavity having a bottom end and a top end;
- degassing a resin mixture to provide a de-aerated resin mixture, the de-aerated resin mixture including a synthetic resin and a curing agent, the curing agent configured to cure the synthetic resin from a flowable state to a solid state;
- injecting the de-aerated resin mixture into the mold cavity to gradually fill the mold cavity from the bottom end to the top end of the mold cavity;
- allowing the de-aerated resin mixture to harden to form the connector boot around the connector of the wire harness;
- and
- demolding the connector boot.
A method of molding an epoxy connector boot over a connector of a wire harness, the method comprising:
- positioning the connector of the wire harness into a mold cavity of a mold, the mold cavity having a bottom end and a top end;
- removing air from an epoxy resin mixture, the epoxy resin mixture including an epoxy resin and a curing agent operable to harden the synthetic resin over a curing time period;
- injecting the epoxy resin mixture into the bottom end of the mold cavity to gradually fill the mold cavity from the bottom end to the top end thereof;
- and
- allowing the epoxy resin mixture to cure inside the mold to form a hardened epoxy connector boot around the connector of the wire harness.
