Below, we will look at the background technology along with the attached drawings.

In general, wall-mounted round mirrors that are used to hang on the wall have a round frame, and in addition to round mirrors, round frames are also sold or used on the edges of round objects such as clocks or furniture.

In order to use it as a frame for a round object including the above-described circular mirror, a conventional method is to mix high-strength polystyrene (HIPS, High Impact Poly Styrene) resin and expandable polystyrene (EPS, Expandable Polystyrene) resin at a weight ratio of 20:80 and then inject it. The frame was manufactured.

Here, expandable polystyrene is hard, and high-strength polystyrene resin is soft because rubber-based components are polymerized into styrene. Conventionally, high-strength polystyrene resin and expandable polystyrene resin are generally mixed at a weight ratio of 20:80 and injected to manufacture the frame. Because the frame manufactured by the conventional injection method lacks flexibility, damage such as breaking or breaking frequently occurs due to lack of flexibility when bending and inserting it into a round object including the round mirror according to the intended use. There was a problem.
