Product Introduction 

The aluminum alloy signal box shell is made of high-quality aluminum alloy profiles. The shell body is manufactured through advanced extrusion molding technology, and then combined with high-precision CNC machining centers for precision secondary processing. It is designed to carry and protect various sensitive electronic signal equipment (such as communication modules, control units, sensor interfaces, etc.). It gives full play to the characteristics of aluminum alloy materials, such as lightweight, high strength, excellent heat dissipation and corrosion resistance, and uses the structural integrity of the extrusion process and the dimensional accuracy of CNC precision machining to create a professional-grade signal equipment shell solution that is durable, has a high protection level, high heat dissipation and exquisite appearance. It is an ideal choice in the field of precision electronic equipment shell customization.

Product Parameter

Product Name Aluminum Alloy Signal Box Shell

Product Material 6061/6063

Processing Technology: Open Die Extrusion/CNC Processing

Product Features: Supports all-round precision customization of size, wall thickness, internal structure, panel layout, interface type, surface treatment, special certification (such as fire protection), etc.

Product Feature And Application

High-strength and lightweight structure (advantages of extrusion):

Using aluminum alloy extruded profiles as the matrix, the one-piece main structure has excellent mechanical strength and rigidity, and effectively resists impact, vibration and extrusion deformation.

Excellent heat dissipation performance (extrusion + CNC):

Aluminum alloy itself has excellent thermal conductivity.

The extrusion process can flexibly design internal heat dissipation teeth or channels to increase the heat dissipation surface area.

CNC precision machining can accurately mill out ventilation holes, heat dissipation grilles or planes for installing heat sinks to ensure efficient heat dissipation inside the equipment and prevent overheating.

High protection level (CNC precision guarantee):

Combined with the high-flatness sealing surface processed by CNC precision milling, the box cover and the box body are tightly combined.

IP65/IP67 or higher protection levels can be customized, which is effectively dustproof, waterproof and moisture-proof, and can adapt to various harsh industrial environments.

The extruded box itself has no seamless or few welds, which reduces potential leakage points.

Precision dimensions and interfaces (CNC core value):

CNC machining centers ensure that the dimensions and position accuracy of all mounting holes (threaded holes, light holes), panel openings (displays, buttons, interfaces), guide rail slots, etc. reach ±0.05mm or even higher.

Meet the strict assembly tolerance requirements of precision electronic components to ensure convenient and reliable equipment installation.

Support the processing of complex special-shaped structures and fine features to achieve high customization.

Application scenarios 

Industrial automation and control: PLC control box, inverter shell, I/O module box, sensor junction box, industrial control computer chassis.

Communication and network equipment: 5G small base station shell, optical fiber terminal box, network switch/router chassis, communication module protection box.

Rail transit: vehicle-mounted signal control unit (VCU/TCU) shell, signal acquisition box, trackside equipment protection box.

Electric power energy: smart meter box, power monitoring terminal (DTU/FTU/TTU) shell, photovoltaic inverter communication module box, charging pile control unit shell.

Internet of Things (IoT) and Smart Devices: Gateway housings, edge computing node chassis, and various smart terminal device housings.

Test and measurement instruments: Precision instrument housings, data logger chassis.

Military and aerospace: Electronic equipment chassis with high requirements for weight, strength, heat dissipation, and shielding (special materials and processes are required).

Product Details

Excellent weather resistance and surface treatment:

Aluminum alloy substrates are naturally corrosion-resistant, and the surface can be anodized (commonly used in natural color, black, and other colors), sandblasted, and sprayed.

The surface treatment is not only beautiful, but also greatly enhances the wear resistance, corrosion resistance, and UV resistance, extending the service life of the housing.

Electromagnetic compatibility (EMC) considerations:

Aluminum alloy itself provides a good electromagnetic shielding (EMI) foundation.

Through structural design (such as conductive gasket groove-CNC processing) and surface conductive treatment (such as conductive oxidation), the electromagnetic shielding performance can be further improved to protect internal sensitive signals from interference.

Flexible customization capability (extrusion + CNC core advantage):

Extrusion die development: Extrusion dies with specific cross-sectional shapes can be developed according to demand to meet the needs of different sizes and internal structures (such as reinforcing ribs), and achieve cost-effective optimization of small-batch to large-batch production.

CNC programming flexibility: CNC processing has extremely high flexibility. By modifying the program, it can quickly adapt to the production of customized shells with different sizes, opening layouts, and interface requirements, responding to the diverse needs of customers.

FAQ

Q: What is the difference between extrusion and die casting of aluminum alloy housing? Which one is more suitable?

A: Extrusion is suitable for producing profiles with constant cross-sectional shape and long length. It has the characteristics of high structural strength, good material density, excellent surface quality, and relatively low mold cost (especially when the cross-section is simple), which is very suitable for box-type structures.

Die casting is more suitable for mass production of complex three-dimensional shapes and thin-walled parts, but there may be pores and the strength is slightly inferior to extrusion parts (same material).

For signal box housings that require high structural strength, good heat dissipation teeth, and high protection sealing surfaces, extrusion molding combined with CNC finishing is usually the better choice.

Q: What key role does CNC machining play in this type of housing?

A: CNC machining is the core link to ensure high precision, high quality, and high customization of products. It is responsible for:

Precisely machining the sealing surface to ensure a high protection level (IP67, etc.). Precision milling of mounting holes, panel openings, and interface holes to meet the strict assembly requirements of electronic components.

Processing of complex internal structures (such as mounting columns, slots) and fine features.

Achieve flexible production of small batches and multiple varieties.

Q: What are the benefits of surface treatment "anodizing"?

A: Anodizing (especially hard oxidation) can significantly improve the surface of aluminum alloys:

Hardness and wear resistance: resist scratches during installation and use.

Corrosion resistance: form a dense oxide film to resist environmental erosion.

Insulation: The oxide film is a good insulator (note that special treatment is required when EMC is required).

Aesthetics: Provide uniform and stable multiple color options.

Q: What is the cycle and cost of customizing such a shell?

A: The cycle and cost depend on complexity, size, and quantity:

Extrusion die development: A one-time die fee is required, and the cycle is about 2-6 weeks (depending on complexity). For standard sections or existing dies that can be reused, it is faster.

CNC programming and processing: The first piece involves programming and debugging time, and subsequent batch production efficiency is high. The main cost of small batch customization is CNC processing time and materials.

Overall: Extrusion + CNC process has very good cost performance and flexibility in the production of customized shells with small and medium batches, high precision and high quality requirements. In large-scale production, the shared mold cost makes the unit price more competitive.
