LED Display Die-cast Cabinet

LED Display Die-cast Cabinet

The die-cast LED cabinet serves as the core structural and protective framework for high-end LED video walls, rental screens, large outdoor displays, and high-definition terminals. Manufactured using an integrated aluminum alloy die-casting process, it combines a lightweight body, high structural strength, superior flatness, rapid assembly capabilities, and sealed protection. Tailored for indoor and outdoor high-definition LED applications, it is a critical component ensuring seamless splicing, high-definition visuals, stable operation, and quick installation and dismantling. It is widely used in scenarios such as stage rental screens, large outdoor advertising displays, conference room screens, retail video walls, traffic guidance displays, and temporary screens for live events.

The LED Display Die-cast Enclosure is precision die-cast from high-purity aluminum alloy as a single, seamless unit, ensuring uniform density and exceptional structural rigidity. Compared to traditional sheet-metal or extruded-profile cabinets, it offers superior flatness and dimensional accuracy, effectively preventing misalignment, unevenness, or gaps between LED modules. This eliminates issues such as visible seams (black lines), image misalignment, and poor surface flatness, thereby significantly enhancing the overall visual performance. Its lightweight design reduces the screen's total load, making it suitable for various installation methods—including overhead suspension, wall mounting, and floor stacking—while ensuring ease of installation and high safety standards.

The Integrated Aluminum Alloy Die-cast LED Display Cabinet offers excellent environmental adaptability and protection. Through precision sealing, anti-corrosive surface oxidation, and dust/moisture-proofing treatments, it achieves a highly sealed structure that effectively blocks dust, moisture, and insects. This protects internal components—such as LED beads, driver boards, power supplies, and wiring—preventing failures caused by moisture-induced short circuits, dust accumulation, image artifacts, or blackouts. An integrated, well-designed heat dissipation chamber facilitates natural convection, efficiently dissipating heat generated during module operation. This prevents performance degradation due to high temperatures and ensures the LED display maintains high brightness and stability during prolonged use. The cabinet features a standardized, modular design equipped with precision locking points, alignment holes, and quick-release latch mechanisms. This ensures accurate alignment and effortless assembly and disassembly, significantly shortening the operational cycle—including setup, teardown, and transport—in rental applications. The design offers high reusability and exceptional resistance to deformation and damage. Engineered to withstand harsh conditions—such as intense sunlight, wind and rain, fluctuating temperatures, and frequent handling—the product is resistant to aging, deformation, and corrosion, while offering high shock and compression resistance; it maintains flatness and stability even after prolonged use. Additionally, OEM/ODM customization is available, allowing for tailored cabinet specifications, mounting layouts, and surface finishes based on screen size, pixel pitch, installation environment, and specific protection requirements. Compatible with a full range of LED display equipment, it provides high-precision, highly reliable, and durable structural support for commercial high-definition display systems.

Product Description: Die-cast cabinets for LED displays, rental LED screens, and large outdoor LED screens; aluminum die-cast housings for LED displays, stage screens, and LED modules; die-cast cabinets for curved LED screen assembly.

Model: OEM/ODM

Base Material: Aluminum alloy die-casting substrate (standard ADC12/A380 or specialized Al-Si alloys); features excellent fluidity, high strength, and superior heat dissipation.

Manufacturing Process: High-pressure aluminum alloy die-casting → Removal of gates and overflows → Shot blasting/sandblasting → CNC machining (milling of mating surfaces; precision machining of locking mechanism and locating pin holes) → Deburring and cleaning → Pre-assembly of locks and corner components → Full dimensional inspection → Airtightness and visual inspection → Surface treatment → Final product inspection.

Precision: Die-cast blank dimensional tolerance: ±0.5–1.0 mm; CNC-machined sealing surfaces and mounting holes tolerance: ±0.1–0.2 mm

Surface Treatment:

1. Natural sandblasting (semi-finished blank; customer-applied coating optional)

2. Chromate passivation / Chromium-free passivation (basic rust protection)

3. Electrostatic powder coating (Colors: RAL, PANTONE, GSB05, etc./custom colors; C3–C5 corrosion resistance rating)

4. Hard anodizing, conductive oxidation

5. Anti-corrosion dip coating, electrophoretic coating

Unit Price: Quoted based on drawings

Packaging:

1. Internal cushioning/protection: Full coverage of the cabinet interior with EPE foam; thickened EPE padding at vulnerable areas—such as corners, heat dissipation vents, and door frame seams—to prevent paint scratches, deformation, or damage caused by bumps and compression during transport.

2. Internal moisture and rust protection: Desiccant placed inside the cabinet to absorb condensation caused by temperature fluctuations in shipping containers, preventing the steel from rusting due to moisture. 3. Comprehensive Moisture-Proof Sealing: The entire unit is fully wrapped in PE moisture-proof and waterproof film to block the ingress of seawater mist and humidity.

4. Carton & Corner Reinforcement: The unit is encased in a heavy-duty, seven-layer export-grade corrugated carton, with solid wood corner protectors installed at all four corners to prevent damage from collisions or crushing during loading and unloading.

5. Bulk Shipment: Units are neatly stacked on heat-treated, ISPM15-compliant solid wood pallets and secured with stretch wrap; this configuration meets global customs quarantine standards for wood products and facilitates forklift handling, container stacking, and long-distance ocean transport.

6. Large-Scale Multi-Section Units: Encased in IPPC-compliant plywood crates; for these large, three-section units, we prioritize the use of sealed, fumigation-free IPPC plywood crates. These offer superior structural rigidity and sealing performance, providing enhanced shock and moisture resistance for long-haul ocean shipping while ensuring smooth customs clearance without quarantine-related delays.

Logistics: sea transportation, air transportation, international express delivery (DHL, FedEx, UPS, TNT), railway transportation (mainly China-Europe trains), road and land transportation (short-distance foreign trade in adjacent countries)
