SILICONE KEYPAD PARTNER
Silicone Conductive Rubber Keypad with Durable Plastic Button Caps
The advanced hybrid plastic-silicone keypad, also known as the P+R keypad or Plastic + Silicone Rubber Keypad, integrates the durability of silicone rubber with the precision of plastic components. Engineered with meticulous detail, it offers superior resistance to wear, dust, and oil, ensuring extended device lifespan. Featuring plastic button caps for enhanced aesthetics and backlighting effects, this keypad undergoes a bonding process for seamless integration, optimizing performance and reliability across diverse electronic applications.
Types of legend and symbol application on plastic button covers:
– Silk Screen Printing
– Laser Etching (including color spraying coating and laser engraving for LED backlight)
– Overmolded legends (utilizing silicone & LSR + plastic overmolding for backlight)
Protective coating options for plastic button and key cap legends:
– UV coating or PU coating (available in glossy or matte smooth finishes, selected based on keycap’s operating environment)
Plastic Silicone Rubber Keypad Production Process:
Advantages of Plastic Rubber Keypads:
– Enhanced aesthetics and backlight effects
– Excellent tactile sensation, oil resistance, and dust protection
– Cost-effective for mass production
– Extended lifespan for P+R keypads
Disadvantages of P+R Keypads:
– High initial investment: Costs associated with plastic injection molds, die-cutting tooling, and positioning tools can be significant. Opting for transparent PC & PMA plastic key caps further increases expenses due to requirements for high-quality mold chamber steels and specialized injection machine gates.
– Labor-intensive assembly process: The production and assembly of P+R keypads require substantial manual labor.
– Not suitable for low-volume production of P+R keypads.
