摘要: An apparatus and method provide for the extrusion of green brick material around a hole-generating member and the use of a lubrication fluid between the hole-generating member and the green brick material to reduce friction therebetween during extrusion, thus enabling the formation of larger sized holes in the bricks formed thereby.
