Commercial light truck high-voltage box shell

Advantages: 

Strict welding standard: Firm, aesthetic weld seams; sheet metal & square tubes welded at perfect vertical angles, zero misalignment.

Full post-weld finishing: Complete weld slag removal, thorough grinding for smooth, flawless surfaces; all burrs, flash edges on holes and panels fully eliminated.

Sharp edge deburring & blunting: All sharp corners and sharp edges rounded off to avoid scratches and safety hazards.

Deformation control system: Stress relief annealing + flat straightening processes to minimize post-processing distortion, ensure flatness meets strict tolerance standards.

Dual fastening solution: Bolts & nuts fully tightened then spot-welded for ultra-reliable, long-lasting connection.

Complete pre-assembly inspection: Every finished cabinet undergoes trial fitting with brackets and covers, all bolts fit smoothly without assembly interference.

Uniform matte sand-texture powder coating with precise thread protection during spraying.

Consistent color coverage, free of pinholes, shrinkage cavities and paint sagging; coating thickness complies with official technical specifications.

Shot blasting pre-treatment before powder coating to boost coating adhesion, anti-rust and anti-corrosion performance.

Quality control system

Every production step is inspected from raw material forming, welding, surface finishing to pre-assembly testing, with all dimensional, appearance, electrical and corrosion indicators strictly aligned with international technical standards, delivering stable, durable and high-standard custom metal & busbar solutions.
