Process & Manufacturing Insights
This enclosure is a prime example of our advanced Casting Services. The manufacturing process leverages state-of-the-art 800-ton high-pressure die-casting machines, ensuring dense, defect-free structural integrity.
High-Pressure Die Casting
Utilizing premium Aluminum Alloys (ADC12/A380/A383), we achieve exceptional dimensional stability and superior heat dissipation, critical for high-power communication devices.
Precision CNC Machining
Following the casting phase, the enclosure undergoes secondary CNC machining to create exact internal mounting bosses, perfectly threaded connector ports, and a seamless gasket groove designed for high IP-rated weatherproofing.
Surface Treatment
The exterior is finished with a high-grade, corrosion-resistant powder coating (customizable to painting, anodizing, or electroplating), providing long-lasting durability against UV rays, moisture, and industrial environments.

Frequently Asked Questions
We offer ADC12, A380, and A383 aluminum alloys as standard options, with magnesium and zinc alloy alternatives also available. ADC12 is ideal for complex shapes requiring excellent castability, A380 provides the best balance of strength and thermal conductivity, while A383 offers superior resistance to cracking under pressure. Our engineering team can recommend the optimal alloy based on your thermal load, structural requirements, and operating environment.
This enclosure is engineered to support IP65 to IP67 ratings depending on your final assembly configuration. Sealing is achieved through precision CNC-milled gasket grooves designed to accommodate silicone O-rings or EMI shielding gaskets. The flat mating surfaces and high-precision casting process minimize porosity, ensuring reliable waterproof and dustproof performance for outdoor and industrial deployments.
Yes. The fin geometry — including fin pitch, height, thickness, and orientation — can be fully customized based on your thermal simulation data or target dissipation wattage. We work with your engineering team to optimize the fin array for maximum passive cooling efficiency, ensuring your PCBs and power modules operate within safe temperature ranges even in high-ambient outdoor environments.
We offer powder coating, liquid painting, anodizing, electroplating, and mirror polishing. For outdoor telecommunication and networking applications, powder coating is the most recommended option due to its superior resistance to UV radiation, moisture, salt spray, and industrial chemicals. Anodizing is an excellent alternative when a thinner, harder, and more electrically insulating surface is required. All surface treatments are fully customizable in color and finish.
We accept a wide range of 2D and 3D design file formats including CAD, PDF, DWG, IGS (IGES), and STP (STEP). Our engineering team will conduct a complimentary Design for Manufacturability (DFM) review upon receiving your files to identify any potential production issues and suggest optimizations before tooling begins, saving you time and cost.
Shenzhen Sunmy Hardware Co.,Ltd. is certified to ISO9001:2015, reflecting our commitment to consistent quality management across all production stages. Our quality control process includes incoming material inspection, in-process dimensional checks using CMM and precision gauges, and final outgoing inspection against agreed tolerances of ±0.1mm (GB5237.1-2008 High Precision Grade). First-article inspection reports (FAIR) are available upon request for new custom projects.
