Thin-gauge steel/aluminum sheets commonly produce obvious springback after bending, causing uneven cabinet door gaps, deformed box outline and poor sealing fit. We adopt customized springback compensation mold design + segmented positioning bending process, control bending angle tolerance within ±0.15°, ensure flatness consistency for cabinet frames and box bodies, eliminate warpage and uneven gap issues in mass production, laying solid foundation for stable waterproof performance.
Conventional batch punching often leads to inconsistent hole spacing, offset mounting holes and mismatched assembly holes, resulting in on-site secondary drilling and assembly failure. We adopt integrated fixture positioning + program-locked CNC punching & laser cutting, unify coordinate benchmark for all hole features, keep hole position tolerance within ±0.2mm, guarantee interchangeability of accessories and greatly improve customer on-site assembly efficiency.
Ordinary assembly deviation will damage IP protection rating and cause rainwater & dust penetration for outdoor cabinets and junction boxes. We use high-precision laser blanking + post-weld grinding finishing, matched with customized silicone sealing groove machining, realize seamless fit between door frame and rubber gasket, stably achieve IP54 / IP65 long-term waterproof & dustproof performance under harsh outdoor wind, rain and temperature fluctuation environment.
Exposed electrical cabinets and junction boxes require neat appearance; traditional welding easily causes thermal deformation, welding pits and rough seams. We deploy pulse precision TIG welding + follow-up fine grinding & deburring treatment, minimize welding deformation, realize near-invisible welding joints, lower rework rate after surface coating and meet high cosmetic standards for finished enclosures.
Outdoor electrical products face long-term UV, rain and moisture erosion, easily leading to paint peeling and rust spots on welding seams and edges. We implement complete pre-treatment workflow: Degreasing → Derusting → Phosphating → Passivation before electrostatic powder coating, effectively solve coating defects; finished products pass 500-hour salt spray test, extending outdoor service life significantly.
