Surface treatment technology: From basic protection to multi-functional integration

The core advantage of silicone keypads [https://www.cmaisz.com/www.cmaisz.com/customizable-silicon-keypad-for-your-needs-product/] lies in their elasticity and weather resistance. And the surface treatment technology further expands their application scope:

1Laser engraving technology: By precisely laser engraving the transparent Silicone Surface layer, it forms light-transmitting characters. It features high precision (micron level) and anti-wear properties, and is widely used in car central control systems and intelligent wearable devices for night interaction recording. The elastic dust-proof fabric structure proposed in the 2024 patent also solves the dust entry problem of traditional hammer keys.

2. Screen Printing Process: Utilizing screen printing technology to achieve customized color and pattern, this method is suitable for marking requirements of products such as remote controls and keypads. The ink has strong adhesion and the cost is controllable.

3. Spraying/Inkjet Printing Process: Enhance the surface feel (such as matte or frosted finish) through PU or UV coating, while also improving water resistance and stain resistance. For instance, UV curing technology can add "anti-stretch protection" to the keypads [https://www.cmaisz.com/www.cmaisz.com/customizable-silicon-keypad-for-your-needs-product/], extending the lifespan of outdoor equipment.

Industrial-grade demand drives technological upgrades

For environments such as those in the medical and automotive sectors that are highly demanding, surface treatment technologies need to meet even higher standards:

1Waterproof and wear-resistant: The multi-layer spraying process combined with chemical treatment (such as electrostatic treatment) can enhance the surface energy of the silicone, ensuring a firm bond between thE Coating [https://www.cmaisz.com/e-coating/] and the substrate, thus enabling the keypads to maintain stable performance even in damp or oily environments.

2Balance of transparency and texture: The hammering engraving technique achieves this through a layered oil-ash design. In the transparent character areas, the soft texture of the silicone is preserved. Meanwhile, the industrial equipment keypads are optimized through the hot pressing process to improve surface flatness and reduce assembly gaps.

Future Trends: Composite Processes and Environmental Innovation

The industry is exploring the combination of various processes, such as:

IMD In-Mold Decoration Technology: Integrating printed pattern films with silicone for one-piece molding, avoiding the risk of subsequent printing detachment, suitable for complex curved surface designs. Plasma Treatment: Through plasma bombardment of the surface, enhancing the adhesion between silicone and coating, especially suitable for the high cleanliness requirements of medical equipment. Additionally, environmentally friendly WV oil and closed-loop recycling technology for laser engraving waste has also become an important direction in green manufacturing.

Conclusion

The "all-round improvement" of silicone keypads is based on the deep synergy between surface treatment technology and materials science. From the delicate touch required in consumer electronics to the extreme environmental adaptation needed for industrial equipment, the innovative combination of six processes is driving this traditional component towards higher performance and intelligence. In the future, with the explosion of scenarios such as 5G and automotive electronics, the surface treatment technology of silicone keypads [https://www.cmaisz.com/www.cmaisz.com/customizable-silicon-keypad-for-your-needs-product/] may open up a broader application space.
