Solve Thin-Plate Bending Springback & Structural Deformation Defect
Thin sheet metal used for communication and smart equipment structures easily generates springback after CNC bending, resulting in deformed outlines, uneven panel gaps and assembly failure. We adopt customized springback compensation mold design + segmented positioning bending technology, controlling bending angle tolerance within ±0.12°, ensuring flatness consistency of chassis frames and precision structural components, eliminating warpage and inconsistent gaps during mass production, greatly improving assembly pass rate.
Eliminate Welding Thermal Deformation, Weld Pits & Visible Seams for High-Precision Chassis
Communication chassis and exposed smart equipment structural parts demand high flatness and appearance quality; traditional welding easily causes thermal deformation, pits and rough weld traces, affecting assembly and shielding effect. We deploy pulse precision laser/TIG welding + follow-up fine grinding & deburring process to minimize heat-affected zone distortion, realizing nearly invisible welding seams, lowering post-surface-treatment rework rate, and meeting high-grade appearance & flatness standards for communication enclosure products.
Control Cumulative Dimensional Tolerance for Multi-Piece Assembled Structures
Precision sheet metal assemblies consist of multiple panels, brackets and mounting fittings; cumulative machining deviation often leads to misalignment during final assembly. We implement first-article 3D coordinate full inspection, unified fixture positioning for all working procedures to lock tolerance chains, guarantee interchangeability of spare parts, simplify your final assembly work and effectively reduce product rejection rate.
Optimize EMI Shielding Structure & Surface Conductive Treatment for Communication Chassis
Ordinary sheet metal chassis often suffer poor seam shielding, signal leakage and unstable conductive continuity. We customize shielding grooves, conductive contact strips and seam lap structures, with targeted conductive coating / nickel plating treatment, ensuring consistent electromagnetic shielding performance, helping communication equipment pass EMC electromagnetic compatibility certification smoothly.
Stabilize Batch Dimensional Consistency for Long-Term Repetitive Orders
Long-term bulk orders easily have batch-to-batch dimensional fluctuation caused by manual positioning deviation. We adopt standardized fixture positioning + program-locked machining parameters, implementing sampling inspection for raw materials, semi-finished products and finished products per batch, keeping dimensional deviation stable in repeated mass production, ideal for long-term framework order cooperation with communication and smart equipment brands.
Improve Coating Adhesion to Prevent Paint Bubbling, Peeling & Edge Rust
Cut edges and welding seams are prone to poor paint adhesion, bubbling and peeling after long-term use. We implement complete pre-treatment workflow: Degreasing → Derusting → Phosphating → Passivation before electrostatic powder coating, enhancing coating binding force; finished products pass 500-hour salt spray test, extending service life for indoor and semi-outdoor communication & intelligent equipment scenarios.
