Premium Aluminum Surface Treatment, 120μm Uniform Sandblasting, PCD High-Gloss Edge & Double Anodizing Finish

This project delivers top-tier customized high-end aluminum surface finishing solutions for ultra-long precision structural parts. Different from ordinary extruded aluminum profiles, the 2920mm hollow profile is fully milled and hollowed out from integral solid square aluminum bar, ensuring superior structural rigidity and flatness to lay a solid foundation for premium surface processing. We adopt exclusive luxury-grade surface treatment technology to restore the classic high-texture metallic finish of iPhone 5S, widely applied in high-end equipment, luxury display devices and high-precision industrial scenarios.Zero-Defect High-End Surface Standard & Full-Range InspectionWe strictly implement luxury consumer-grade surface finishing standards. The entire aluminum profile undergoes 100% full manual and precision visual inspection, eliminating all surface defects including scratches, pits, burrs, color spots and uneven texture. Every finished product presents consistent, delicate and high-grade metallic appearance, meeting ultra-high aesthetic and functional requirements of premium equipment manufacturing.Precision Custom 120μm Uniform Sandblasting & Premium Apple Gold AnodizingAs the core procedure of high-end surface finishing, customized 120μm thick uniform sandblasting is adopted for overall surface treatment. Controlled by precise process parameters, the sandblasting layer achieves uniform thickness, delicate matte grain and zero color difference across the whole profile surface, avoiding common flaws of ordinary sandblasting such as uneven texture and local thickness deviation. Combined with exclusive Apple Gold anodizing treatment, the profile restores the iconic luxurious metallic tone, with stable color adhesion and excellent anti-oxidation performance.PCD Ultra-Precision High-Gloss Edge Finishing & Secondary Reinforced AnodizingTo create layered high-end surface texture, we use imported PCD precision milling cutters for mirror-level high-gloss polishing on four edges of the profile. The processed edges are smooth, sharp and transparent, forming a distinct delicate layering with the matte main surface. The final secondary reinforced anodizing process locks the surface gloss and color stably, effectively improving wear resistance, corrosion resistance and texture durability of the high-end finish, realizing long-term non-fading and non-scuffing performance.High-End Surface Finishing AdvantagesCompared with conventional aluminum surface treatment, our integrated process of solid bar precision machining + customized sandblasting + double anodizing + PCD high-gloss polishing achieves dual upgrade of structural performance and surface grade. The whole process focuses on high precision, zero defect and luxury texture, providing one-stop high-end aluminum surface finishing customization for high-end automation, intelligent equipment, luxury display and high-precision industrial manufacturing fields.
