Abstract

This invention relates to a method to form front and/or back flanges on metal plate material by extrusion method. The method comprises making a die opening hole on the metal plate blank, bending the rim of the plate to form a bent-edged plate, putting a die around the perimeter of the bent edge of the plate, and putting a mandrel in the die opening hole. By using punch head to press on the top end of bent edge of the plate, the material is extruded to move along the mandrel and form front and/or back flanges around the perimeter of the die opening hole.
