Conprofe Technology Co., Ltd.

The PC industry is undergoing a structural transformation. While conventional notebook segments face growth headwinds, AI PCs and agentic PCs are rapidly evolving, unlocking fresh momentum for the global notebook market. With on‑device intelligence redefining human‑computer interaction, next‑generation devices are shifting from pure productivity tools to intelligent companions. This upgrade drives not only hardware performance improvements but also a clear trend toward premiumisation. In this landscape, visual branding—particularly the LOGO—has become a critical differentiator for high‑end models.

For consumers, the LOGO is the most direct visual touchpoint that signals intelligence, personalisation, and quality. Its material, craftsmanship, and finish must resonate with the smart attributes of AI‑native products. For premium SKUs, the requirement has moved far beyond mere legibility. A finish that combines visual impact, layered depth, a technological aesthetic, and dynamic light‑interaction effects is increasingly viewed as a value‑added option for differentiation. Conprofe’s ultrasonic rainbow‑finish machining technology precisely addresses this brand‑visual upgrade need, delivering LOGO surfaces that are both tactilely refined and visually distinctive.

Where Current LOGO Processes Fall Short for Premium Devices

Existing LOGO processes—screen printing, laser engraving, and separated backlighting—serve mainstream models well in terms of volume and basic aesthetics. However, for higher‑tier AI PC and agentic PC products, each has inherent limitations:

• Screen printing offers reasonable abrasion resistance but limited visual variety; it is prone to scratches and colour fading over time, falling short of premium quality standards.

• Laser engraving improves durability and can achieve a clean, tech‑oriented look, yet it exposes the bare substrate, making the surface susceptible to irreversible scratches and lacking the dynamic visual presence needed for flagship devices.

• Separated backlighting provides good surface protection but introduces structural seams that trap dust; its complex internal architecture raises manufacturing and repair costs, while adding bulk that contradicts the slim‑and‑light design ethos of high‑end notebooks.

A Purpose‑Built Innovation: Conprofe Ultrasonic Rainbow‑Finish Technology

For high-end notebook LOGO processing, conventional techniques struggle to simultaneously satisfy multiple critical criteria: insufficient abrasion resistance, monotonous light-and-shadow effects, relatively high processing costs, and inconsistent surface quality across workpieces. The limitations of legacy approaches become increasingly apparent as brand owners demand more sophisticated visual expressions for their flagship AI PC and agentic PC models.

Responding to the this rigorous demands, Conprofe has developed an ultrasonic rainbow‑finish machining solution tailored to the stringent demands of premium consumer electronics. The technology uses high‑frequency ultrasonic embossing to create fine, three‑dimensional textures on the workpiece, which generate dynamic light‑shifting effects. This overcomes the conventional trade‑offs among visual richness, haptic quality, and process efficiency.

More precisely, the ultrasonic machining system converts high-frequency electrical energy into mechanical vibration during processing. While the MCD scraper engages the workpiece, the system imposes tens of thousands of vibrations per second, creating periodic separation between the tool and the workpiece surface, leaving nano-level ironing-and-pressing textures on the surface. These textures function as grating structure and refract incident light to produce bright, vivid, and richly layered rainbow-colour effects by dynamically adjusting the pitch and angle of the gratings—transforming a functional surface into a visually compelling brand signature.

Validated Performance: A Case Study on 7075 Aluminium LOGO Processing

In a typical project machining a 7075 aluminium alloy laptop LOGO (100×50×10 mm), the Conprofe UGR‑400 Ultrasonic‑Green Rainbow‑Finish Machining Center—integrated with our proprietary ultrasonic system and MCD scraper tools—demonstrates clear advantages:

• For convex patterns, unidirectional scraping achieves excellent surface consistency and vivid rainbow-finish colours, with an average roughness Ra of 0.1547 μm and a cycle time of 15 minutes 28 seconds.

• For concave lettering, contour‑following scraping delivers fine detail in just 32 seconds, with Ra as low as 0.1013 μm.

Both processes enhance tactile quality and optical depth, meeting the dual requirements of premium aesthetics and manufacturing efficiency.

Beyond Finishing: A Versatile Platform for Next‑Generation Manufacturing

The UGR‑400 series features an integrated ultrasonic spindle for process stability, a MQL cooling system, a labyrinth‑type triple‑layer sealing structure, and optional high-precision probe for in‑process measurement. It supports not only rainbow finishing of non‑ferrous metals for consumer electronics, but also precision micro‑hole machining and high‑gloss finishing of hard‑brittle materials, composites, and difficult‑to‑cut metals—offering true multi‑purpose versatility.

As AI PC and agentic PC penetration continues to rise, the demand for LOGO finishes that convey uniqueness and premium value will only intensify. Conprofe’s ultrasonic rainbow‑finish machining solution provides a distinct innovation path that resolves visual monotony, mediocre tactility, durability concerns, and structural bulk. It empowers brands to strengthen product differentiation, unlock pricing premiums, and contribute to the broader upgrade of high‑end surface processing across the intelligent device value chain.
