Title
(EN) PLASTIC PRODUCT WITH STIFFENING PROVISIONS, AND METHOD FOR MANUFACTURING SAME
(FR) PRODUIT EN PLASTIQUE AVEC APPORT DE RAIDISSEMENT ET PROCEDE POUR LE FABRIQUER
Abstract
(EN)
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.
(FR)
L’invention concerne un produit en plastique moulé par injection avec au moins une paroi dont au moins un côté a une longueur ondulée, de telle sorte que l'épaisseur de la paroi dans au moins une direction est alternativement plus petite et plus grande avec une forme continue. L'invention fournit également un procédé de fabrication de produits en plastique, selon lequel : au moins une paroi du produit est formée dans une cavité de moule par moulage par injection ; une partie de la cavité de moule qui forme ladite paroi a au moins une partie de la paroi du moule mobile, qui est mobile entre une position rentrée et une position avancée ; lorsque la partie de la paroi du moule mobile est en position rentrée, du plastique est introduit dans la partie respective de la cavité de moule et ensuite ladite partie de la paroi du moule mobile est disposée en position avancée, de telle sorte que le plastique dans ladite partie de la cavité de moule se répande, ladite partie de la paroi du moule mobile et/ou une partie opposée de la paroi du moule étant formée de telle sorte qu'une surface ondulée soit obtenue sur au moins un côté de la paroi à former, de telle sorte que l'épaisseur de paroi de la paroi respective dans une direction ait une forme continue alternant les parties épaisses et minces.
