发明名称 Stylus flashlight housing and method for making same
摘要 A method for making a flashlight housing comprises providing a blank of an electrically conductive material, impact extruding the blank of electrically conductive material to form an elongated hollow member that has an internal cavity open at a first end and that has a reduced inner diameter portion proximate a second end thereof, and coating the elongated hollow member with a coating material. The flashlight housing may have a tail cap, and may have O-rings for sealing at the rearward end of the tail cap, at the forward end of the housing, and/or at the interface between the housing and the tail cap.

主权项 1. A method for making a flashlight housing comprising the steps of: providing a blank of an electrically conductive material; impact extruding the blank of electrically conductive material to form an elongated hollow member that has an internal cavity open at a first end and that has a reduced inner diameter portion proximate a second end thereof; said impact extruding comprising forming the internal cavity and the reduced inner diameter portion of the elongated hollow member substantially contemporaneously utilizing a core tool having a first portion defining the internal cavity of the elongated hollow member and having a second portion forward of the first portion thereof for defining the reduced inner diameter portion of the elongated hollow member; and coating the elongated hollow member with a coating material.
