Process for the realization of door and window frames made of plastic material

Abstract

The process for the realization of door and window frames made of plastic material comprises: - a step of providing a profiled element (1) made of plastic material for the realization of door and window frames; - a step of providing a reinforcing element (8) made of metal material, the profiled element (1) having a containment seat (6) of the reinforcing element (8); - a step of inserting the reinforcing element (8) inside the containment seat (6); - a step of fixing the reinforcing element (8) to the profiled element (1) by means of fixing means (9) between at least a portion of the profiledelement (10) and at least a portion of the reinforcing element (11); wherein the fixing step comprises a heating step of the portion of the reinforcing element (11) by means of electromagnetic induction means (12), the fixing means (9) being adapted to cooperate with at least one of the portion of the profiled element (10) and the heated portion of the reinforcing element (11) for the fixing of the portion of the reinforcing element (11) to the portion of the profiled element (10).

Description

technical field [0001] The invention relates to a method for realizing a door and window frame profile made of plastic material. Background technique [0002] A real need is known to provide frames, such as doors and windows, which ensure a certain degree of thermal insulation between the interior and the exterior environment in order to reduce energy consumption. [0003] There is even such a need in the field of door and window frames made of plastic materials (in particular, PVC), although these frames already have higher insulation properties compared to commercially available metal frames due to the lower thermal conductivity of plastics. hot sex. [0004] These profiles are made of plastic resin and have a specific multi-cavity structure inside the profile itself, which ensures a high degree of thermal insulation. [0005] The main disadvantage of the plastic profile parts realized in this way is their poor resistance to stresses and movements imposed by externally a...

AI Technical Summary

Problems solved by technology

[0010] The main disadvantage of the plastic door and window frames thus realized is the insufficient thermal insulation between the interior and the external environment separated by the frame itself, and the associated energy supply costs in order to maintain the required temperature in the internal environment

[0011] Another disadvantage lies in the method of realization of such frames, since drilling the profile to be able to insert the fixing screws implies the formation of chips from the plastic profile and any debris to be removed from such machining methods. excess material residue

[0012] Furthermore, the realization methods of the known type may cause imperfections on the visible surface of the profiled part, thereby impairing the aesthetic appearance and the general conforming appearance of the profiled part itself

[0013] Yet another disadvantage is the processing time required to fix the reinforcement to the profile by means of fixing screws, as well as the high mechanical and associated maintenance costs for manufacturing the profile itself

[0014] Another disadvantage is the high energy consumption required by machines of the known type when realizing the profile, especially when screwing the reinforcement to the profile itself, since compressed air screwing systems are characterized by a non-negligible energy consumption

[0015] The inconvenience is also associated with the noise disturbance caused by the drilling operation of the profiled parts by screwing systems of known type
