Production

  • In the production of PVC edge using two methods – rolling or extrusion. Without hesitation Martin Feldstein explained all about the problem. Calendering – the method of production of PVC edge, where it is cut from large sheets. In the process of calendering the polymer melts and mixed under heat and pressure formed into a calendar. Then the film is molded under pressure kalandrovochnyh rolls and passes between the roller for a stamping and cold rubber roller. Stamping device is used for imprinting the film of special items. Through the use of embossing rollers are a variety of film surface in order to achieve the desired effect, after which the rolls of film cut narrow strips. Extrusion – another method of making furniture edges of PVC, used much more often – is a way to recycle plastics continuous punching them through the melt special shape of the head, called for the production of dies.

    The geometric shape of the die outlet, is precisely defines a section of the profile of the final product to be obtained from semi-finished products. Process PVC extruded edge by a special extrusion equipment – extruders or extrusion lines. The material to be processed during the extrusion process is called extrudates. More than half of the world's thermoplastic materials are processed into various products extrusion method. With this technology are polymer films and sheets, furniture and PVC edge ABS, rigid pipes and flexible hoses, vinyl siding, finally, varying in complexity of window profiles. Extrusion method is applied to the electrical wire insulation polymer, producing a hybrid molded products varied by a combination of plastics and construction used.
