AKKO’s most representative electroplated keycap product to date is the “Quantum Horizon” collaboration model, launched in August 2026 in partnership with OSHID. Instead of the traditional approach of electroplating the entire keycap surface, it innovatively treats the electroplated layer as a “3D armor”—an electroplated component that wraps around the PC (polycarbonate) base, creating a dual-layer structure featuring internal light transmission and an external protective shell. This design preserves the light-transmitting properties of the PC material while using the electroplated frame to provide a metallic aesthetic and unique light-reflective qualities.
I. Quantum Horizon: Electroplating as a “Structural Component” Rather Than a “Decorative Layer”
Traditional electroplated keycaps typically involve applying a metal film directly to the surface, resulting in a mirror-like metallic sheen across the entire keycap. However, this approach has obvious drawbacks: the electroplated layer comes into direct contact with fingers and is prone to wear over time; the fully electroplated surface creates harsh reflections under RGB backlighting, often turning the keycap into a distorting “funhouse mirror”; and fingerprint smudges are almost unavoidable.
“Quantum Horizon” takes a different path. It features an innovative, patented structure: an outer layer of 3D silver-plated armor and an inner layer of matte, dual-injection molded PC. Crucially, this electroplated armor is not merely a sticker or coating applied to the surface, but an integral part of the keycap’s structural design. In other words, the electroplated component acts as an independent “armored frame” that encases the PC keycap body.
This structural design yields three direct benefits.
First, the electroplated layer is not subjected to frequent direct contact. Fingers primarily touch the PC keycap surface, while the electroplated armor is positioned along the frame and stepped edges, significantly reducing the risk of wear.
Second, the lighting effects possess greater depth and nuance. The inner PC base handles the RGB backlighting, allowing light to diffuse naturally from within, while the outer silver-plated armor blocks stray light and confines the illumination to the character patterns. Simultaneously, the glossy surface of the armor reflects both ambient light and the keyboard’s own illumination, creating a “liquid silver” aesthetic.
Third, the tactile feel is more practical. The stepped profile created by the electroplated rim slightly reduces the contact surface area compared to traditional keycaps, though the impact is minimal. The PC base features a matte finish; while transparency is low, it allows light to pass through, creating a superb, soft glow that is easy on the eyes and avoids the greasy, slippery feel often associated with highly transparent PC materials.
II. Three-Layer Composite Process
The manufacturing process for “Quantum Horizon” can be summarized as a three-layer composite structure: from outside to inside, these are the 3D silver-plated armor, the matte PC dual-injection molded base, and high-precision screen printing.
The outer electroplated armor gives the keycap a sculptural, three-dimensional look and a cool, metallic tactile feel. The inner matte-translucent PC base ensures the keycap’s structural toughness and light-transmission capabilities. High-precision screen printing (with 0.05mm accuracy) is applied over the silver-plated armor, layering “glitch-style” tech patterns onto the surface; the characters feature sharp, clean edges and offer excellent wear and abrasion resistance.
Notably, Quantum Horizon utilizes high-precision screen printing rather than dye-sublimation. This indicates that the electroplated armor’s surface treatment requires a screen-printing process for compatibility: the high temperatures involved in dye-sublimation could compromise the bonding stability between the electroplated layer and the PC base, whereas screen printing cures at room temperature, exerting minimal physical or chemical impact on the electroplated layer.
III. Design Language: Glitch Aesthetics and Mecha Style
The visual theme of Quantum Horizon centers on “digital glitch aesthetics.” The design team takes moments of digital chaos—such as visual noise, image tearing, color shifting, and signal interference—and recalibrates them into a controlled design language through the “precise order” of the 3D silver-plated armor.
Programming symbols such as “404 Error,” crash reports, and garbled signal text are incorporated into the keycaps, transforming system crash visuals familiar to programmers and digital enthusiasts into surface design elements. This design direction targets a demographic of custom keyboard enthusiasts, tech lovers, and programmers.
IV. Process Boundaries of Electroplated Keycaps
The Quantum Horizon solution illustrates a key trend: the application of electroplating technology to keycaps is shifting from “full-surface coating” to “structural component plating.” This shift is driven by several practical constraints.
Long-term contact between the electroplated layer and the user’s fingers. No matter how wear-resistant the electroplated coating is, it still wears down faster than PBT or PC base materials when subjected to frequent, direct contact. Designing the electroplated part as an enclosing structure rather than the actual contact surface is a sensible choice for extending its visual lifespan.
Regarding the compatibility of dye-sublimation with electroplating: dye-sublimation requires high temperatures exceeding 230°C, whereas the stability of electroplated coatings and PC substrates at such temperatures differs from that of PBT. The fact that the “Quantum Horizon” (Liangzi Shijie) series utilizes screen printing instead of dye-sublimation indicates that the process for applying graphics to electroplated keycaps is constrained by the thermal properties of the materials.
The core value of the AKKO “Quantum Horizon” series lies in its redefinition of electroplating from mere “surface decoration” to a “structural component.” The electroplated “armor” is not simply a metal film applied to the keycap; it is an integral part of the keycap structure itself. This approach resolves the contradiction inherent in traditional electroplated keycaps—where they looked good but performed poorly—by separating functions: the metallic aesthetic is provided by the armor, while the PC substrate handles physical contact; meanwhile, light shines through the inner PC layer, with the armor serving to contain and reflect that light. For users who desire a metallic look without sacrificing practicality, this represents a highly pragmatic manufacturing approach.
