Challenge:Traditional trailer coupler lock designs combined the ball head and housing into a single die casting component, creating challenges in mold design, metal flow control, and casting quality.
Solution: Ruiyu optimized the product structure by separating the ball head and housing, improving die casting feasibility and reducing wall thickness issues during production.
Challenge:The customer required improved corrosion resistance for an aluminum die casting housing used in outdoor environments.
Solution: Ruiyu optimized the surface treatment process by combining electrophoresis coating and weather-resistant powder coating.
