Injection molded lipstick casings move in large volumes through decorating and assembly operations using robotics. This automation requires each part to be oriented in these trays in exactly the same position and must not rotate while traveling from one location to another.
Because of the fine quality decoration applied to these cosmetic products, contamination caused by poor trimming of the trays can result in defects. This quality requirement by the customer necessitates a more advanced trim tool than is commonly used. In addition, the forming of the tray cavities with extreme ratios requires a thermoform tool that parallels injection molding tools.
