Abstract[English]
The present disclosure is concerned with a method of making an insert for an injection molding machine comprising the steps of providing a metal block, removing material from the metal block by eroding and/or milling so that at least one depression is formed for at least partly defining a mold cavity for molding a first component of a two-component plastic part, the depression being defined by at least one bordering wall of the metal block, where between a base surface of the depression and at least a portion of the bordering wall a material transition area is present having a first radius, removing material from the material transition area by applying laser light so that the resulting material transition area has a second radius smaller than the first radius.[French]
La présente divulgation concerne un procédé de fabrication d'un insert pour une machine de moulage par injection comprenant les étapes consistant à fournir un bloc métallique, à enlever de la matière du bloc métallique par érosion et/ou fraisage de sorte qu'au moins une dépression soit formée pour définir au moins en partie une cavité de moule pour le moulage d'un premier composant d'une pièce en plastique à deux composants, la dépression étant définie par au moins une paroi de bordure du bloc métallique, entre une surface de base de la dépression et au moins une partie de la paroi de bordure, une zone de transition de matière présente ayant un premier rayon, à enlever de la matière de la zone de transition de matière par application d'une lumière laser de sorte que la zone de transition de matière résultante ait un second rayon inférieur au premier rayon.
