P+R Keys with Laser-Carved Translucent Legends for Backlight Compatibility

Product Overview

The P+R Translucent-Legend Key is a precision-engineered composite button featuring a spray-coated surface with laser-carved characters that enable uniform backlight illumination from beneath—specifically designed for POS terminals and other applications requiring reliable backlight readability. The manufacturing process begins with a durable spray coating applied to the keycap surface, followed by precision laser engraving that removes the coating in precise character patterns, allowing LED light from the bottom layer to pass through with exceptional clarity. This combination of spray coating and laser carving ensures that legends remain crisp, wear-resistant, and visually striking over the product's lifetime—even under the heavy daily use typical of POS terminals in retail, hospitality, and banking environments.

Constructed through precision two-shot injection molding, the rigid plastic base and soft silicone contact layer are bonded seamlessly, delivering both structural stability and comfortable tactile feedback. ES Silicone's advanced laser systems, backed by 20+ years of process refinement and our own silicone and plastic factories, achieve consistent engraving depth and uniform light transmission across every key. Our senior engineering team, with experience across 1,000+ P+R projects, conducts comprehensive DFM reviews to optimize spray coating thickness, laser parameters, and mold design—ensuring consistent quality across high-volume production runs for POS terminals and other demanding applications.

Core Advantages

1. Precision Laser-Carved Translucent Characters for Uniform Backlighting : Advanced laser engraving technology precisely removes the spray coating in character patterns, creating sharp, permanent legends that allow LED light from beneath to transmit uniformly. ES Silicone's 20+ years of laser process experience and in-house engineering support ensure consistent character depth and light transmission across every key—critical for POS terminals requiring clear visibility in low-light retail and hospitality environments.

2. Durable Spray Coating for Long-Lasting Surface Protection : A high-performance spray coating is applied to the keycap surface before laser engraving, providing resistance against abrasion, fingerprints, and chemical exposure. The coating maintains its integrity even after laser processing, ensuring that the surrounding surface remains protected while the carved characters allow backlight to pass through. Our own silicone and plastic factories and 1,000+ completed P+R projects give us deep expertise in selecting and applying coatings that meet the durability demands of POS terminal applications.

3. Precision Two-Shot Injection Molding for Seamless Integration : The plastic base and silicone contact layer are bonded in a single molding process, eliminating secondary assembly and achieving dimensional tolerances as tight as ±0.02mm. ES Silicone's in-house engineering team conducts comprehensive DFM reviews to optimize mold design and process parameters for consistent quality across high-volume production runs. With our own mold-making capabilities, 20+ years of industry experience, and a senior engineering team, we deliver reliable, production-ready solutions for POS terminals and beyond.
