Description:
Automotive Compression Molding Silicone Rubber Keypad Keyboards are high-performance, precision-crafted interfaces produced using silicone compression molding. We use premium-grade Liquid Silicone Rubber (LSR) or High-Temperature Vulcanized (HTV) silicone, ensuring exceptional temperature resistance (-50°C to 250°C), superior tactile feedback, and enhanced durability against UV exposure and chemicals. Our ISO 9001 and IATF 16949-certified facility offers comprehensive, one-stop solutions, ranging from 3D prototyping and mold design to production that complies with UL and ROHS standards. We also conduct extensive validation testing, including IP67/68 ratings and 100k+ cycle endurance tests. These keypads are ideal for automotive OEMs requiring custom shapes, backlighting, or EMI shielding, all supported by full traceability and fast lead times.

Manufacturing Process:
- Precision Mold Design
CNC-machined steel molds with ±0.05mm tolerance replicate tactile button contours, symbols, and automotive-grade sealing features.
- Material Preparation
High-consistency silicone rubber (HCR) is compounded with conductive carbon (for ESD resistance) and UV stabilizers, meeting ISO 9001/IATF 16949 standards.
- Compression Molding
Pre-weighed silicone blanks are cured under 300–350°F heat and 1,500–2,500 PSI pressure for 5–10 minutes, ensuring uniform density and tear-resistant edges.
- Post-Vulcanization
Secondary baking (250°F, 2–4 hrs) eliminates residual volatiles, enhancing thermal stability (-40°F to 392°F) and compression set resistance.
- Laser Engraving/Backlighting
Symbols/icons are laser-etched or filled with translucent silicone for backlit functionality (IP67-rated).
- Dimensional Inspection
3D laser scanners (Keyence) and durometers (Shore A 40–60) verify thickness (±0.1mm) and tactile feedback compliance.
- Electrical & Durability Testing
Automated keystroke testers (50,000+ cycles), ESD/EMI shielding checks, and chemical resistance validation (SAE J1455).
- Automotive-Grade Packaging
Anti-static, moisture-proof packaging with batch traceability for OEM/Tier 1 integrations.
Benefits of Our Keypad:
- Precision Tactile Performance
CNC-machined molds (±0.05mm) ensure consistent button actuation force (100–300g) and IP67-rated sealing for dust/water resistance.
- ESD & UV Resistance
Carbon-black-infused silicone and UV stabilizers comply with SAE J1455, preventing static buildup and cabin UV degradation (-40°F to 392°F).
- Durability-Optimized Molding
High-pressure compression (2,500 PSI) eliminates air pockets, achieving tear-resistant edges and >500,000 keystroke cycles (per OEM-TS 16949).
- Thermal Stability
Post-vulcanization reduces compression set (<20% at 158°F/70hrs), ensuring long-term resilience in extreme automotive environments.
