Plastic product with stiffening provisions, and method for manufacturing same
A plastic injection molded product with at least one wall which on at least one side has a wavy course, such that the thickness of the wall in at least one direction is alternately smaller and larger with a flowing course. The invention also provides a method for manufacturing plastic products, wherein at least one wall of the product is formed in a mold cavity by injection molding, wherein a portion of the mold cavity which forms said at least one wall has at least one movable mold wall part which is movable between a retracted position and a forwardly moved position, wherein, with the movable mold wall part in the retracted position, plastic is introduced into the respective part of the mold cavity and then said movable mold wall part is brought to the forwardly moved position, such that the plastic in said part of the mold cavity is spread, said movable mold wall part and/or an opposite mold wall part being formed such that on at least one side of the wall to be formed a wavy surface is obtained, such that the wall thickness of the respective wall in one direction has a flowing course between alternately thick and thin parts.
