<![CDATA[Damage to door panels caused by drilling, nailing, or screwing clothes hangers onto doors, as well as the insufficient strength of conventional hangers, remains a common problem in residential and public facilities. This production project aimed to develop a durable S-shaped 90° clothes hanger made of aluminum that can be attached directly to the edge of a door with a thickness of 38 mm without causing structural damage. The production method consisted of several stages, including designing the S-shaped 90° hanger, cutting an aluminum plate measuring 210 × 20 × 3 mm, forming semicircular ends using a press tool to reduce the plate length from 21 cm to 20 cm, filing sharp edges, marking bending lines at distances of 3 cm and 7 cm from both ends of the plate in opposite directions, bending the ends according to the markings, and applying paint or anodizing finishes based on customer preferences. The final stage involved quality and dimensional inspections to ensure product conformity. The resulting product was an aluminum S-shaped 90° clothes hanger capable of being securely hung on the upper edge of a 38 mm thick door. The production cost was approximately IDR 12,000 per unit, with an average manufacturing time of 10 minutes per unit. The hanger was capable of supporting loads of up to 7 kg and could be easily installed, removed, and relocated without damaging the door surface.]]>
