Overview:

Compression Molding Metal Dome Silicone Rubber Keypad Keyboards are robust and versatile input devices commonly used in medical devices, electronic equipment, and industrial applications. Crafted from high-quality silicone rubber and featuring metal domes for superior tactile feedback, these keypads are produced using silicone compression molding technology. This ensures precision, durability, and consistent performance in every unit.

At our factory, we specialize in OEM production of custom silicone rubber keypads, tailored to meet the unique needs of various industries. With extensive expertise in material selection, advanced molding techniques, and stringent quality control measures, we deliver high-performance keypads designed for long-lasting reliability and functionality. Whether for medical, industrial, or electronic applications, our custom keypads provide the ideal solution for demanding environments.

Basic Information:

Production Process:

1. Raw Material Preparation– Premium silicone rubber is carefully selected, mixed, and prepared to ensure optimal molding performance.
2. Compression Molding– The prepared silicone material is placed into a precision mold, then compressed under high temperature and pressure to form the keypad structure with accurate details.
3. Surface Treatment– Various surface finishing techniques, including silk screen printing, laser etching, PU coating, or epoxy coating, are applied to enhance durability, appearance, and functionality.
4. Metal Dome Integration– Metal domes are precisely positioned on the contact points to provide tactile feedback and enhance switch response.
5. Conductive Printing (if applicable)– Conductive inks or carbon pills are applied to designated contact areas to ensure proper electrical conductivity.
6. Cutting and Punching– The molded keypad undergoes cutting and punching processes to achieve the required dimensions and specifications.
7. Adhesive Backing Application (if needed)– A custom adhesive layer is applied to the back of the keypad for easy assembly onto circuit boards or enclosures.
8. Quality Inspection & Testing– Each keypad undergoes stringent inspections, including functional testing, dimensional checks, and durability assessments, ensuring compliance with all specifications.
9. Packaging & Shipment– The completed keypads are carefully packaged per customer requirements and prepared for shipment.

Quality Assurance:

Our quality management system, certified to ISO9001 and IATF16949 standards, oversees every stage of production, from raw material selection and mold fabrication to final product inspection. We employ state-of-the-art testing equipment, such as 3D measuring instruments, sealing testers, durometers, elasticity measurement tools, and high-precision life cycle testers, to ensure dimensional accuracy, consistent tactile feedback, and long-term durability.

Furthermore, we implement stringent process controls, conduct in-line inspections, and perform final quality checks to ensure compliance with ROHS and other relevant industry standards. This comprehensive quality assurance process guarantees that every keypad meets the highest benchmarks for performance, reliability, and tailored customer specifications.
