An improved mold releasing technique including use of moveable segments to form a part of the male portion of the mold, and the unique product formed thereby is described. The moveable segments which disengage from integral contact with the product once it is formed, permit the formation of the uniquely formed product which includes side and end walls which can be less than 1 degree off vertical. This enables the manipulation of the product design parameters including each wall angle at various points along the wall to achieve a desired wall surface profile especially in the vicinity of the product floor. This results in an increased surface area at or near the product floor which permits a greater number of animals to be housed in the cage product in accordance with Federal guidelines. The tailoring of the wall profiles also allow for the nesting of the products and the accommodation of prior art covers and accessories.
