Abstract
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 at the interface between the housing and the tail cap.
Claims15
A method for making a flashlight housing comprising the steps of:
- providing a blank of an electrically conductive material;
- deep drawing 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;
- coating the elongated hollow member with a coating material;
- and
- drilling or boring the reduced inner diameter portion of the elongated hollow member at least for removing coating material from the reduced inner diameter portion.
A method for making an elongated flashlight housing comprising the steps of:
- providing a blank of an electrically conductive material;
- providing a core tool having a portion defining an internal cavity and having a portion defining a reduced inner diameter portion at a forward end of the internal cavity;
- deep drawing the blank of electrically conductive material with the core tool to form an elongated cylindrical hollow tube of electrically conductive material;
- wherein the elongated cylindrical hollow tube has an internal cavity, has a reduced inner diameter portion at the forward end of the internal cavity, and has a rounded forward end;
- drilling or boring a longitudinal cavity in the reduced inner diameter portion of the elongated cylindrical hollow tube;
- and
- forming an opening through the rounded forward end of the elongated cylindrical hollow tube including drilling or boring a circular hole in the rounded end of the elongated cylindrical hollow tube.

- providing a core tool having a portion defining an internal cavity and having a portion defining a reduced inner diameter portion at a forward end of the internal cavity;
- deep drawing the blank of electrically conductive material with the core tool to form an elongated cylindrical hollow tube of electrically conductive material;
- wherein the elongated cylindrical hollow tube has a narrowing exterior taper at a forward end thereof, has an internal cavity, has a reduced inner diameter portion at the forward end of the internal cavity, and has a rounded forward end;
- drilling or boring a circular hole in the rounded forward end of the elongated cylindrical hollow tube,
- coating the elongated cylindrical hollow tube with a coating material;
- and
- after said coating, then drilling or boring a longitudinal cavity in the reduced inner diameter portion of the elongated cylindrical hollow tube, wherein coating material, if any, on the reduced inner diameter portion is removed.
