Abstract
Método para fabricación de perfiles plásticos asimétricos. Tiene especial aplicación en los perfiles plásticos obtenidos por inyección, macizos y de los empleados en industrias del automóvil, plástica, etc. La fabricación puede llevarse a cabo por extrusión o moldeo. La longitud del perfil, al ser muy grande en proporción con sus otras dimensiones, es lo que crea el problema de deformación o arqueamiento, conocidos, tras el experimento de la pieza. Acorde con la invención, se evita la deformación al prever una ranura longitudinal (2) en el perfil (3, 6), para provocar una rotura térmica en la masa del mismo y equilibrar las tensiones debidas al enfriamiento, de las secciones resultantes a uno y otro lado de dicha ranura (2), la cual queda situada en la zona precisa para lograr tal efecto. Esta ranura (2) se encuentra lógicamente practicada en la cara inferior u oculta del perfil.Method for manufacturing asymmetric plastic profiles. It has special application in plastic profiles obtained by injection, solid and used in the automotive, plastic, etc. industries. The manufacture can be carried out by extrusion or molding. The length of the profile, being very large in proportion to its other dimensions, is what creates the known deformation or bowing problem, after the experiment of the piece. In accordance with the invention, deformation is avoided by providing a longitudinal groove (2) in the profile (3, 6), to cause a thermal break in the mass thereof and balance the stresses due to cooling, of the resulting sections to one and another side of said slot (2), which is located in the precise area to achieve this effect. This slot (2) is logically made on the underside or hidden side of the profile.
