Compression molded silicone keypad

A Compression molded silicone keypad  is an electronic control component integrally formed via compression molding or liquid silicone injection molding, with high-elasticity silicone rubber as the base material. It serves as the core functional part for human-machine interaction on remote controls. The back of each key is integrated with conductive carbon pills or metal contacts: when pressed, the silicone deforms elastically to bring the conductive layer into contact with the PCB board, completing circuit conduction and command transmission; when released, the silicone rebounds rapidly by its own elasticity to break the circuit and return to its original state. Integrating three core functions of conductive triggering, tactile feedback and sealing protection, it is an indispensable component for all remote control devices.

IX. Frequently Asked Questions (FAQ)

Q1: Are you a factory or a trading company? What is your MOQ?
Aobo Silicone is a professional silicone product manufacturer with our own factory in Dongguan, Guangdong, equipped with an in-house mold workshop and production lines. The standard MOQ for customized products is 3,000 pieces. Small quantities of stock samples are available for testing; please contact our sales representative for details.

Q2: How long does sampling take? Is there a sample charge?
Sampling for new molds generally takes 5--7 working days; samples from existing molds can be shipped within 2--3 days. For first-time cooperation, we provide 3--5 free samples with freight collect. Special customized samples may incur a sampling fee, which will be deducted from your bulk order payment.

Q3: What is the service life of a Compression molded silicone keypad?
Standard consumer-grade keypads have a press life of ≥500,000 cycles, while industrial-grade models can exceed 1,000,000 cycles. Under normal household daily use, the service life reaches 5--8 years; in high-frequency industrial scenarios, it is approximately 2--3 years, varying with usage frequency and environmental conditions.

Q4: Can you produce waterproof keypads? What is the highest protection rating?
Yes, we offer waterproof structure customization. Basic integrated keypads achieve IP65 dust and water protection; with an added waterproof skirt and sealing structure, the rating can reach IP67, suitable for short-term immersion and high-pressure spray environments.

Q5: Will the surface characters peel off? What character processes are available?
We use high-adhesion wear-resistant ink or laser engraving technology, so characters will not easily peel off under normal use. Available processes include standard silk-screen printing, wear-resistant coating, laser engraving with ink filling, and dispensing raised characters. Laser engraving offers the best alcohol wipe resistance, ideal for medical and industrial applications.
