Abstract

The method applies especially to solid plastic sections obtained by injection and those used in the automotive and plastics industries, etc. Manufacturing may take place by means of extrusion or moulding. The length of the section, being very great in proportion to its other dimensions, is what gives rise to the problem of deformation or bending, which are known after experimentation on the article. According to the invention, deformation is prevented by providing a longitudinal groove 2 in the section 3, 6 to give rise to a thermal break in the mass of the section and to balance the stresses, arising from cooling, in the resulting sections on either side of said groove 2 which is located in the precise region for achieving said effect. This groove 2 is logically made in the lower or concealed face of the section.
