Benefits of Our Products:
-
Enhanced Conductivity Consistency
– Automated carbon pill dispensing systems with ±0.1mm positional accuracy ensure uniform electrical contact resistance (<5Ω variance), critical for calculator keypad signal reliability.
-
Optimized Cycle Time Efficiency
– Precision compression molding (175°C/30sec cure) combined with in-mold carbon pill integration eliminates post-assembly steps, achieving 15% faster production throughput vs. traditional adhesive methods.
-
Superior Durability via Material Synergy
– Co-vulcanization of carbon-loaded conductive compounds (Shore A 50±3) with LSR matrix prevents pill delamination, sustaining >10M actuations (per IEC 60384-21 cyclic testing).
-
Reduced Scrap Rates with Process Control
– Real-time SPC monitoring of mold parameters (pressure: 150±5 bar, temp: ±1°C) and vision-guided pill placement minimizes defects (<0.2% reject rate), aligning with Six Sigma methodologies.
Surface Coating Options for Silicone Keyboards:
-
Polyurethane (PU) Coating
This highly resilient and flexible coating offers superior protection against abrasion, chemicals, and UV degradation. It provides a glossy, smooth finish, ensuring long-term durability and enhanced product longevity.
-
Matte Smooth Coating
Designed to reduce glare, this non-reflective coating delivers a sleek, smooth surface with a soft-touch texture. It is resistant to fingerprints and stains, making it ideal for maintaining a high-quality appearance in everyday use.
-
Epoxy Coating
Known for its exceptional adhesion and chemical resistance, epoxy coating creates a durable, high-gloss finish. This robust coating is perfect for heavy-duty applications, offering superior resistance to environmental stress and wear.
-
Laser Silicone Coating
This advanced coating technique enhances tactile feedback and wear resistance. Utilizing precision laser technology, it allows for the creation of custom patterns that not only improve the functionality of the keypad but also add an aesthetic touch.
