| Surface roughness | Ra ≤ 1.6 μm | Thermal shock test | -55℃ ~ +85℃, 100 cycles |
| Peel strength | ≥15 kgf (enhanced stability) | Mating durability | ≥500 cycles, or per customer requirement |
| Salt spray test | 24h / 48h / 96h (customizable) | Contact/Pad plating | PCB pad with 0.38 μm Au / 1.27 μm Ni; contact area customizable |

Quality and Certification
GuangWei operates under ISO 9001, ISO 14001, and IATF 16949 certified quality systems, ensuring process traceability and stable mass production. All enclosures comply with RoHS and REACH environmental directives.
Third-party verification (ICP / SGS) and full CMM dimensional reports are available upon request. Production supports custom drawings, 3D model validation, and tolerance control per customer design.
Packaging and Logistics
Each zinc die casting server enclosure is individually packed in an anti-static plastic bag, then placed into protective EPE foam compartments to prevent surface abrasion or impact. Units are consolidated into sturdy 5-ply export-grade cartons, sealed and labeled with part number, quantity, and batch code. Palletized packaging is available for bulk shipments.
