collaborated with an outdoor leisure brand to customize high-strength hardware connectors for outdoor swings, including core parts such as hooks, chains and fixing buckles. Using 45# high-toughness carbon steel, through precision stamping and quenching processes, the tensile strength is increased by 60%, which can bear a load of 150kg, suitable for both adults and children. An innovative anti-drop double insurance buckle is designed to eliminate the hidden danger of falling off during use. The surface is hot-dip galvanized, rust-proof and resistant to outdoor wind and rain erosion, suitable for outdoor scenarios such as courtyards and parks. This customized connector helped the partner’s swing products pass safety certification, with sales increasing by 49%, becoming a popular supporting product for outdoor leisure furniture
