Product Advantages

01 | 55×15mm Ultra-Wide and Ultra-Thin Design

The 55mm wide × 15mm high cross-section size provides an extremely slim packaging solution for ultra-thin smart devices.

The 55mm width is wider than the common 52mm specification, accommodating larger PCB layouts and supporting more side-by-side function modules and interface design; the 15mm ultra-thin height is one of the thinnest specifications currently available in the aluminum enclosure industry, giving devices a card-like ultra-thin profile and greatly enhancing product quality perception and technological appeal. The 15mm thickness can accommodate standard 1.6mm thick PCBs and surface-mount components, making it the best choice for LED strip controllers and other ultra-thin devices.

02 | 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.

03 | 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 15mm height is precisely designed to accommodate standard 1.6mm thick PCBs and surface-mount components.

04 | CNC Custom Machining Support

The standard profile is only the starting point. Boyuan Hardware can perform CNC machining on the 55×15mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, Type-C, DC power interfaces, terminal blocks, etc.)
• Indicator light holes
• Button holes
• Mounting holes and positioning holes
• Threaded holes and counterbore holes
• Heat dissipation structures
• Grooves and steps
• Chamfering
• Other custom structures

05 | Length Customizable to Product

55×15mm 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.

06 | Efficient Heat Dissipation Performance

Aluminum alloy has excellent thermal conductivity. Combined with the 55mm wide-body design and the large heat dissipation surface of the aluminum enclosure itself, it can effectively help internal power devices dissipate heat and extend the service life of LED controllers and other equipment.

07 | 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 ultra-thin devices a more refined product texture.

08 | Suitable for Embedded Installation

The 15mm ultra-thin thickness makes the 55×15mm aluminum enclosure very suitable for embedded installation in narrow spaces — such as inside LED strip channels, inside walls, inside furniture, and inside equipment — without occupying extra space.

What Products Is the 55×15mm Aluminum Enclosure Suitable For?

55×15mm belongs to the ultra-wide and ultra-thin aluminum enclosure category — the 55mm width accommodates larger PCBs and more side-by-side function modules, and the 15mm height achieves a card-like ultra-thin profile. The 15mm ultra-thin height is the core feature of this specification, making it one of the thinnest aluminum enclosures in the industry, especially suitable for ultra-thin smart devices and LED control products with extreme thickness requirements.

1. LED Strip Controllers and Dimmers

55×15mm is an ideal packaging solution for LED strip controllers:

• Constant voltage/constant current LED driver modules

Why is 55×15mm suitable for LED strip controllers? LED strip controllers usually need to be installed side by side with the LED channel or embedded inside the strip channel, where installation space is extremely limited. The 15mm ultra-thin height allows the controller to be easily placed inside a standard LED channel (commonly 12-16mm in height) or attached to the back of the strip, without protruding from the surface. The 55mm width can accommodate a wider PCB, supporting side-by-side layout of multiple output interfaces (RGBW four channels). The aluminum alloy enclosure helps dissipate heat from the driver chip and MOS transistors, extending controller service life. Compared with the 52×13mm specification, 55×15mm is wider and slightly taller, accommodating slightly taller components with broader applicability.

2. Electronic Price Tags and Electronic Labels

• Supermarket electronic price tags
