The platform is mounted on the working stage and includes channels, a curved pattern portion and plural tiny holes which are arranged on the top surface of the platform, wherein the plurality of tiny holes communicate with the channels. The platform also includes a connector fixed on one side thereof and communicating with the channels. The heating device is secured on a bottom end of the platform and heats a working material on the platform. The vacuum means is arranged in the machine frame and includes a pipe for coupling with the connector. The gas barrier film is flaky and covers the top surface of the platform.
Abstract:
A multilayer decorative film structure is attached to and shaped on multiple processing surfaces of a preformed three-dimensional structural part, where the processing surfaces form a three-dimensional shape. An adhesive layer thereof is adhered to the processing surfaces. The bilayer structure, located at a side of the adhesive layer, includes a thermoplastic film and a decorative film. The thermoplastic film has an inner surface and an outer surface. The decorative film is laminated at a side of the thermoplastic film and has a decorative structure. Within a thermal shaping temperature range of the multilayer decorative film structure, the bilayer structure and the adhesive layer is attachable and shapeable onto the processing surfaces of the preformed three-dimensional structural part. When lower than the thermal shaping temperature range, the bilayer structure and the adhesive layer is solidified into a shape as the same as the three-dimensional shape of the processing surfaces.
Abstract:
A method for producing an environment protective foamed thermoplastic resin polymer comprises using an extruder with a helical rod to be driven to rotate. The extruder has a feeding section, a melting section, a mixing section and a heating-shaping section formed therein. The method includes a plurality of steps, in which thermoplastic resin is heated, melted in the melting section and moved into the mixing section, and hollow expansion balls are fed into the extruder to be evenly mixed with the melted thermoplastic resin. Then the hollow expansion balls are slightly heated and inflated, and moved into the heating-shaping section, and then the balls are heated at foaming temperature, foamed and inflated. After being injected through a nozzle, the melted thermoplastic resin and the hollow balls become a foamed thermoplastic resin polymer with a preset thickness and shape.
Abstract:
A reflective film structure is provided for being adhered and shaped on multiple processing surfaces of a preformed structural element, in which the processing surfaces form a three-dimensional shape. The reflective film structure includes a thermoplastic adhesive film and a reflective layer. The thermoplastic adhesive film has a thickness ranging from 0.01 mm to 1 mm, and has an internal surface and an external surface. The internal surface is adhered to the processing surfaces. The reflective layer is laminated on the external surface, and massive beads are distributed on an outer surface of the reflective layer. The reflective film structure has a normal direction vertical to the reflective layer. Furthermore, the reflective layer has at least a first and a second reflective region in different directions, which are respectively towards different directions other than the normal direction. The first and the second reflective region are respectively disposed with beads.
Abstract:
A method for forming thermoplastic composites includes: (a). cutting a thermoplastic film and a cloth material, with the thermoplastic film including a surface layer and an adhesive layer, and with a melting point of the surface layer higher than the adhesive layer; (b). placing the thermoplastic film on a platform of a molding machine, facing the adhesive layer upwardly, and covering the cloth material on the thermoplastic film, with the platform including a plurality of channels defined therein, a plurality of concave and convex patterns arranged on a top surface thereof, and plural pores evenly formed on the top surface thereof and communicating with the plurality of channels; and (c). heating the thermoplastic film by using a heating unit to melt the adhesive layer and to soften the surface layer.
