ティを充満させる。次いで冷却固化すると表面に前記し
た金属箔を重ね合せた布が付着した成形品が得られる。First, an injection mold is prepared, which is covered with a cloth overlaid with the metal foil described above. Hot molten resin is extruded into this mold from an extrusion nozzle to fill the mold cavity of the reflector of the parabolic antenna. Then, when it is cooled and solidified, a molded article having the above-mentioned cloth layered with metal foil adhered to the surface is obtained.
この成形品を金型から取り出した後、もしくは取り出し
の際、表面に付着した該布を剥離すると金属箔とともに
該布表面の形状、凹凸、模様等が転写された優れた反射
特性を有するパラボラアンテナ用反射鏡が得られる。After or when taking out the molded product from the mold, when the cloth attached to the surface is peeled off, the shape, irregularities, patterns, etc. of the cloth surface are transferred along with the metal foil, making it a parabolic antenna with excellent reflective properties. A reflector for use is obtained.
金属箔を重ね合せた布地をインサートする方法は、従来

用いて貼り付けるのは簡便な方法であり、又、適当な機
械的な方法により布地を設置することもできる。The method for inserting the fabric layered with metal foil can be the same as the method for inserting conventional plastic films. In this case, it is a simple method to attach the fabric to the mold using double-sided tape or the like, or it is also possible to install the fabric by an appropriate mechanical method.
その他、市販のインモールド装置を用いてもよい。In addition, a commercially available in-mold device may be used.

転写される。In the present invention, when a hot melt resin is injected into a mold, a molded body is formed on the surface of which a cloth made by overlapping metal foil placed in the mold is attached. At this time, the metal foil is fixed to the molded body by the action of heat and pressure, and when the fabric is peeled off, it is transferred onto the molded body.
