FIELD: production of plastic windows and doors.
SUBSTANCE: technical result is achieved by a method of performing reverse molded elements for placing a weld of plastic profiled elements, in which the reverse molded elements have a main body made with the possibility of receiving in the pressed state a pair of profiled elements made of plastic material, welded together to obtain a frame for windows/doors. Each profiled element contains a welding surface that can be welded to the welding surface of another profiled element in a welding configuration in which the sides of these profiled elements are essentially close to each other and define the detection surface. Moreover, the specified method includes the phase of obtaining the profile of a part of the specified sides; the phase of determining the profile of the contact surface of the specified main body, made with the possibility of receiving the specified detection surface in the pressed state, and the profile of the specified contact surface is essentially complementary to the profile of the specified detection surface; the three-dimensional molding phase achieved by the three-dimensional molding device to obtain the specified main body, starting from the profile of the specified contact surface obtained in the specified determination phase.
EFFECT: technical result is a simplified design and easy adaptation of the reverse molded elements in accordance with the profiles of the profiled elements, reduction of the time and cost of producing reverse molded elements, increasing uniformity and eliminating the bulge of the welding seam.
