Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for forming a gasket of a synthetic resin molded article which makes it possible to form the gasket along a peripheral portion of the synthetic resin molded article with a simple method without the need for a die for molding.SOLUTION: A gasket 9 is formable at a front end portion of a corresponding rib wall 3 with a simple method. That is, setting is made by attaching a tool 5 to a peripheral flange 2 of a synthetic resin molded article 1 with a holding part 6 interposed therebetween. Unfoamed thermoplastic elastomer foam is foamed and loaded along a seal material receiving groove 7 of the tool 5 by a seal material application nozzle 10 at room temperature and ambient pressure, and this is then solidified.
【課題】成形用のダイを必要とすることなく簡単な方法により合成樹脂成形品の周縁部分にガスケットを形成することができる合成樹脂成形品のガスケット形成方法の提供を図る。【解決手段】合成樹脂成形品1の周縁フランジ2に抱持部6を介して治具5を係着してセットし、該治具5のシール材受け溝7に沿ってシール材塗布ノズル10により未発泡の熱可塑性発泡エラストマーを常温大気圧下で発泡させつつ充填して、これを固化させる簡便な方法で対応するリブ壁3の先端部にガスケット9を形成することができる。【選択図】図2 |
