52×52mm Aluminum Industrial Control Box Enclosure

Boyuan 52×52mm Aluminum Industrial Control Box Enclosure is a mid-sized electronic device housing manufactured with an aluminum alloy extrusion structure, with an external cross-section size of 52mm (width) × 52mm (height), and the length can be customized arbitrarily according to actual equipment requirements.

The product is formed by aluminum profile extrusion, with a fixed main body cross-section size. It can be cut according to the actual length of the equipment, and final assembly is completed through end plates, CNC machining, and other supporting processes. The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior of the housing is designed with standard circuit board card slots, and the PCB can be directly inserted and fixed without additional screws, greatly improving assembly efficiency.

Compared with plastic boxes, aluminum alloy enclosures have better structural strength and a metal texture, and can achieve custom structures such as interfaces, mounting holes, threaded holes, and slots through CNC machining.

Core Advantages

01 | 52×52mm Square Large Space

The 52mm wide × 52mm high square cross-section size provides ample internal space for mid-sized electronic equipment.

The 52mm width can accommodate wider PCB layouts and side-by-side design of multiple interfaces, supporting multi-channel input/output interface layouts; the 52mm height provides extremely large component mounting space, can accommodate taller components such as large electrolytic capacitors, transformers, heat sinks, relays, and inductors, and also supports multi-layer PCB stacking or high-power device mounting with large heat sinks.

02 | Square Cross-Section, Flexible Installation

The square cross-section design of 52×52mm gives the enclosure greater flexibility during installation. The mounting direction can be adjusted arbitrarily according to equipment space requirements, adapting to different assembly scenarios and equipment layout requirements.

03 | Aluminum Extrusion Structure

The enclosure body is formed by aluminum alloy profile extrusion. The cross-section size of the aluminum extrusion enclosure is fixed, while the length can be cut according to actual product requirements. Therefore, the same specification enclosure can adapt to PCBs and electronic modules of different lengths. This structure is especially suitable for electronic products requiring series development.

04 | Suitable for PCB Mounting

The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior is standard-equipped with circuit board card slots, and the PCB can be directly inserted and fixed without additional screws. The 52mm height can accommodate multi-layer PCB stacking or high-power devices with large heat sinks, providing a reliable packaging solution for high-power electronic equipment.

05 | CNC Custom Machining Support

The standard profile is only the starting point. Boyuan Hardware can perform CNC machining on the 52×52mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, RJ45, aviation plugs, BNC interfaces, power interfaces, DB9, etc.)
• Screw holes and positioning holes
• Threaded holes and counterbore holes
• Heat dissipation slots and ventilation holes
• Screen window openings
• Button holes and switch holes
• DIN rail mounting holes
• Wall-mounting holes
• Grooves and steps
• Chamfering
• Other custom structures

06 | Length Customizable to Product

52×52mm is the cross-section specification of the enclosure, and the product length can be cut according to the actual equipment dimensions. The specific machinable length is confirmed according to material, surface treatment, and product requirements.

07 | Efficient Heat Dissipation Performance

The thermal conductivity of aluminum alloy is about 200W/(m·K). Combined with the large-area enclosure and ample internal space of 52×52mm, it can effectively conduct and dissipate heat generated by internal components. For high-power equipment, the aluminum enclosure itself is an efficient heat sink, which can extend equipment service life.

08 | Metal Enclosure Combines Structure and Appearance

Aluminum alloy is lightweight and has good structural performance, while retaining a natural metal texture. Through surface treatments such as brushing, sandblasting, and anodizing, different appearance effects can be obtained, giving electronic equipment a more professional product appearance.
