Abstract
A precision mold insert and method for manufacturing angled or angled and bumpered multi-fiber ferrules. The precision mold insert includes an angled end face forming portion, one or more optional bumper forming portions, one or more fiber bores for receiving one or more fiber bore forming pins, and one or more guide pin holes for receiving one or more guide pin hole forming pins. A method for manufacturing a precision mold insert for molding angled or angled and bumpered multi-fiber ferrules utilizing electrical discharge machining (EDM) process and/or a poly crystalline diamond (PCD) grinding tool is provided. The mold insert is used to produce a multi-fiber ferrule having a pre-molded angled end face that is not machined, polished or otherwise altered subsequent to the molding process. The ferrule may also include bumpers for polishing end portions of optical fibers positioned within the fiber bores without altering the angled end face.
