Core Competitive Advantages & Technical Difficulties We Have Overcome (Differentiated Selling Points)

1. Resolve Thin Plate Bending Springback & Housing Deformation Defect

   Thin-gauge cold rolled and galvanized steel sheets are prone to obvious springback after bending, causing irregular outline, uneven panel gaps and assembly jamming. We adopt customized springback compensation mold design + segmented positioning bending process, control bending angle tolerance within ±0.15°, ensure flatness consistency of smart and multimedia equipment shells, eliminate warpage and uneven gap defects during mass production, greatly improving assembly yield.

2. Eliminate Welding Thermal Deformation, Welding Pits & Visible Seams for High-Appearance Equipment Shells

   Multimedia and intelligent equipment exposed housings have ultra-high requirements for exterior finish; conventional welding easily causes thermal deformation, pits and rough welding traces. We adopt pulse precision TIG laser welding + subsequent fine grinding & deburring process to minimize heat affected zone deformation, realize nearly invisible welding seams, reduce post-coating rework rate, and satisfy high-grade appearance standards for commercial terminal housings.

3. Control Cumulative Dimensional Tolerance for Multi-Part Matching Assembly

   Equipment shells consist of front panels, middle frames, rear housings and mounting brackets; cumulative machining deviation often leads to poor fitting between screen, circuit board and casing. We implement first article 3D full coordinate inspection, unified fixture positioning for all working procedures to lock tolerance chain, guarantee interchangeability of spare parts, simplify your final assembly work and lower product rejection rate.

4. Upgrade Galvanized Steel Surface Treatment to Solve Coating Peeling & Edge Rust Problems

   Galvanized steel surface has passive film that easily causes poor paint adhesion, bubbling and peeling, and cutting edges are prone to rust after long-term use. We deploy targeted pre-treatment process for galvanized substrates: special degreasing + surface activation + phosphating passivation before powder coating, effectively enhance coating adhesion; finished products pass 500-hour salt spray test, effectively extending service life for indoor and semi-outdoor equipment scenarios.

5. Stabilize Batch Consistency for Large-Volume Repetitive Orders

   Long-term bulk orders often suffer dimensional fluctuation between batches due to manual positioning errors. We adopt fixture standardized positioning + program locked machining parameters, implement sampling inspection for each batch of raw materials, semi-finished products and finished products, keep dimensional deviation stable in long-term repeated orders, suitable for large-scale mass production cooperation for intelligent and multimedia equipment brands.
