A die-cast LED display case is a high-precision industrial hardware housing specially designed for LED display equipment, manufactured through professional precision die casting processes. Different from ordinary plastic or stamping casings, it adopts ADC12 aluminum alloy as the core raw material, combined with CNC machining, mechanical polishing and anodized surface treatment technology. This series of sophisticated craftsmanship endows the product with ultra-high durability and premium surface finish, making it the mainstream housing solution for industrial LED display equipment.
Produced by Chinese professional hardware manufacturer XingHang Precision Hardware, the XH-092 model die-cast LED display case has passed multiple authoritative certifications and is widely used in diverse industrial application scenarios. It perfectly solves the pain points of poor heat dissipation, easy deformation, short service life and low precision of traditional LED display casings.
2. Core Definition & Key Manufacturing Technologies
2.1 Definition of Die-Cast LED Display Case
The die-cast LED display case is a structural protective shell for LED display modules, control panels and industrial display terminals. It integrates protection, heat dissipation, installation and aesthetic functions. Relying on high-pressure precision die casting technology, the aluminum alloy liquid is pressed into precision molds at high speed and high pressure to form one-piece molded casing blanks, which are then finely processed to meet industrial-grade precision standards.
2.2 Four Core Manufacturing Processes
2.2.1 Precision Die Casting
As the core process of the product, precision die casting realizes one-piece integral molding of the casing. It effectively avoids structural gaps and assembly errors caused by split splicing, and improves the overall structural stability and pressure resistance of the LED display case.
2.2.2 Anodized Aluminum Treatment
The surface adopts anodized aluminum process, which forms a dense protective oxide film on the surface of the ADC12 aluminum alloy. This greatly enhances the product’s oxidation resistance, corrosion resistance and scratch resistance, and maintains a long-term stable high-quality finish in harsh industrial environments.
2.2.3 CNC Machining
Equipped with high-precision CNC machining equipment, it performs precise drilling, cutting, tapping and edge trimming on the cast blanks. The dimensional tolerance is controlled within CT4-CT6 level, ensuring precise matching with LED display modules and no assembly deviation.
2.2.4 Polishing & Integrated Surface Treatment
After fine polishing and multi-layer surface treatment processes, the product surface reaches a smooth Ra 1.6–3.2µm finish. It not only eliminates burrs and sharp edges, but also improves the texture and dust-proof performance of the casing, meeting industrial high-standard appearance and use requirements.

It can quickly export the heat generated by the LED display during long-term operation, reduce equipment temperature, and prolong the service life of LED equipment.
4.3 Structural Stabilization Function
The one-piece die-cast molding process makes the casing have strong structural integrity. It is not easy to deform or loose after long-term use, ensuring the flatness and installation stability of the LED display screen, and avoiding display distortion and screen shaking problems.
4.4 Environmental Adaptation Function
With the help of anodized surface treatment, the casing has excellent anti-corrosion, anti-oxidation and anti-aging capabilities. It can stably operate in high temperature, high humidity and dusty industrial environments, realizing long-term zero-maintenance use.
5. Core Advantages of Precision Die-Cast LED Display Cases
5.1 Superior Material Performance
Adopting high-standard ADC12 aluminum alloy raw materials, compared with plastic casings, it has higher strength, better heat dissipation and stronger environmental resistance; compared with ordinary stamping iron casings, it is lighter, more corrosion-resistant and has a higher finish.
5.2 High Precision & Good Consistency
Relying on precision die casting + CNC secondary finishing, the product dimensional error is controlled at the micron level. The batch product consistency is extremely high, which is convenient for standardized assembly and large-scale supporting use of industrial LED display equipment.
5.3 Durable & High-Quality Finish
Through fine polishing and anodizing process, the surface is smooth and delicate, without burrs and scratches. The color is uniform and stable, not easy to fade and peel off. It maintains a high-grade industrial appearance for a long time and improves the overall grade of LED display equipment.
5.4 Strong Industrial Adaptability
The product has passed ISO9001/TS16949/RoHS/ISO14001 multi-authority certifications, meeting international industrial safety, environmental protection and quality standards. It is suitable for all kinds of professional industrial display scenarios, with wide application coverage.
5.5 Integrated Molding & Cost-Effective
One-piece die-cast molding reduces assembly processes and parts costs. While ensuring performance, it effectively controls the overall production cost, bringing higher cost performance for industrial equipment supporting.
