We are a full-process precision sheet metal manufacturer specializing in tailor-made indoor & outdoor electrical cabinets, waterproof dustproof junction boxes and metal chassis housings with laser cutting and punching processing. We have overcome widespread industry troubles: thin plate bending springback deformation, inconsistent hole position precision in mass punching, poor sealing matching leading to water/dust ingress, welding thermal distortion and uneven coating defects on cabinet surfaces. Equipped with automatic laser cutting, CNC punching, CNC bending, precision welding and complete surface treatment workshops, we strictly control dimensional tolerance and IP sealing performance. We provide one-stop OEM & ODM customization for electrical distributors, automation system suppliers, engineering contractors and equipment manufacturers worldwide, delivering stable mass production, tight lead time and cost-optimized structural solutions.
Solve Thin Plate Bending Springback & Cabinet Deformation Defect
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.
Fix Cumulative Position Deviation in High-Volume Punching & Multi-Hole Machining
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.
Resolve Sealing Groove Mismatch & Water/Dust Leakage Risk for Outdoor Enclosures
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.
Eliminate Welding Thermal Deformation, Pits & Uneven Seams for High-Appearance Cabinets
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.
Optimize Surface Treatment to Prevent Coating Bubbling, Peeling & Rusting
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.
