Abstract:
A molding machine for making thermoplastic composites contains: a machine frame, a platform, a heating device, a vacuum member, and a gas barrier film. The machine frame includes a working stage. 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. 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 member 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 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 producing an environment protective foamed thermoplastic resin polymer uses an extruder installed inside with a helical rod driven to rotate. The extruder has its interior formed with a feeding section, a melting section, a mixing section and a heating-shaping section. 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 after moved into the heating-shaping section, the balls are heated at foaming temperature, foamed and inflated. After injected through a nozzle, the melted thermoplastic resin and the hollow balls together become a foamed thermoplastic resin polymer with a preset thickness and shape.
