より、工程が簡素になり、設備費も節減できる。The method for manufacturing a reflector for a parabolic antenna according to the present invention involves injection molding a plastic base material, and then opening the mold while leaving the base material in the fixed side or movable side mold of the injection molding machine without releasing the mold. Then, by supplying a metal film for forming a reflective layer such as an At' film between these molds and clamping the molds again, since the thickness of the metal film is thin, this metal film can be applied to the concave curved surface of the base material. It is possible to mold the metal film into a shape that follows the concave curved surface and to fix it to the end surface including the concave curved surface using the adhesive applied to the metal film at almost the same time.Therefore, there is no wrinkles in the A film on the gold, and the mold clamping of the injection molding machine is easy. The metal film can be bonded to the base material with a large and uniform force using pressure, and the metal film and base material can be bonded together at an appropriate temperature.The adhesive strength is high, and the metal film does not peel off, resulting in a high-quality product. . Furthermore, in the manufacturing method of the present invention, the mold opening and mold closing of the injection molding machine are performed in two steps.
Although this process is performed one at a time, compared to press-forming the metal film in a separate process, it does not require a press machine and only requires one set of molds, which simplifies the process and reduces equipment costs.

チックスの母材のものと同様である。In this example, it is necessary to set the temperature of the fixed side and movable side molds to around 180°C, which is necessary for the thermosetting reaction of thermosetting plastics, and the adhesive applied to the metal film. Although it is necessary to use urethane, acrylic, or one-component epoxy that is heat resistant to temperatures around 180° C., it does not require preheating of the metal film. Therefore, a preheating device of the manufacturing equipment is also unnecessary. Note that the manufacturing method and manufacturing apparatus for the embodiment using the thermosetting plastic base material other than those described above are the same as those for the thermoplastic plastic base material.

れに＜＜、品質のよい製品が得られる。As explained above, in the method for manufacturing a reflector for a parabolic antenna according to the present invention, after injection molding a plastic base material, the base material is molded into the fixed side or movable side mold of the injection molding machine without releasing the base material from the mold. The mold is opened with the metal remaining inside the mold, a metal film for forming a reflective layer such as an AI film is supplied between these molds, and the mold is clamped again to shape the metal film into a shape that follows the concave curved surface of the base material. While molding, the metal film can be integrally fixed to the end surface including the concave curved surface with an adhesive applied to the metal film, so that wrinkles do not occur on the metal film, and it can be uniformly fixed by the mold clamping pressure of the injection molding machine. The metal film can be pressed onto the base material with a large force, and the metal film and the base material can be bonded together at an appropriate temperature.The adhesive strength of these is high, and the metal film does not peel off easily, resulting in a high-quality product.

う効果がある。Furthermore, in the manufacturing method of this invention, mold clamping and mold opening are performed twice, but compared to methods in which the metal film is press-formed in separate processes, a press machine is not required, and only one mold set is required, making the process simpler. This has the effect of reducing equipment costs and producing products at lower prices.
