There are some methods to make silicone rubber keyboard: compression molding, liquid injection molding(LIM), insert molding, overmolding.Will choose the most suitable method according to the silicone keyboard design or requirements. We will look at two of the most common methods of silicone keyboard.

Silicone backlit keyboard are the core components of many keyboards, which is made of high elastic silicone rubber. Silicone keyboard are optionally provided with some legends&patterns to change visual and tactile impressions. In order to achieve different applications, customer usually require silicone keyboard to gather with different legends & button pattern.

Laser etching keyboard is used for the keyboard that requires backlight effect. We solved many problems of engraved keyboard for clients, sharing with you our cases. Spraying color of graphics, then color of keyboard surface, set graphics on laser machine, then laser etch graphics, this is the processing of painted laser etching keyboard.

Rubber Keypad - Actuation Force? When you design your rubber keypad, you must want to receive excellent tactile feedback when press the keypad buttons. Actuation force of keypad is the force that initiate conduction of buttons connecting with PCB, which gives operators tactile feedback when pressing

Silicone overmolding is also known as rubber overmolding, liquid silicone overmolding, lsr overmolding, insert overmolding, multi-shot injection molding, as a process that apply silicone rubber part - overmold onto the second part - substrate by compression molding, transfer molding, plastic injection overmolding or liquid silicone rubber injection molding(LSR overmolding ). By silicone overmolding, silicone rubber part will form a bonding with the substrate. Silicone overmolding is widely used for overmolding silicone, overmolding rubber, overmolding glass, overmolding plastic(PP, PC, ABS ), overmolding metal, silicone overmolding electronics, medical silicone overmolding, etc. Such as TPU/TPE overmolding, cable overmolding, fabric overmolding, overmolded connector, pcb overmolding, overmolded gasket, overmolded o ring, etc.

Rubber Overmolding is that connect two or multi color rubber parts, dual hardness rubber parts, or different rubber material parts together into a complete final rubber product by compression molding. In rubber buttons overmolding production, multi coloured buttons or dual hardness buttons are molded into a colorful and functional rubber keypad. Overmolding rubber buttons can be with beautiful appearance as the parting lines of colored buttons are clear with any color beeding. In addition, overmolding rubber keypad with dual hardness can have better tactile feel feedback to meet customers’ different actuation force requirements.

Silicone Multicolor Keyboard also known as colour keypad, colour keyboard, colorful button pad, which is made from silicone rubber, a kind of elastomeric translucent synthetic material, with colored keyboard & button keys. Silicone multicolor keyboard which need different colors keys, but don’t want the colors mixed, buttons hardness & durometer are different from the key web or not all the buttons at the same hardness. Overmolding process is a good choice , Xiamen Better Silicone Co., Ltd

An overview of what is elastomer keypad, how do elastomer buttons work, button pad manufacturing process, what affects silicone rubber pad actuation force, why is the silicone keyboard jammed and silicone button classification in surface symbols, protection coating and conduction(Design Guide).

What causes keys/buttons to stuck on a keyboard? For a silicone rubber keypad manufacturer, the stuck key condition is a poor function, which directly affects the quality and normal use of the keypad. There are many reasons that cause keypad button stuck. There is reason for case and also for silicone button. Following share the reasons why some of the silicone key can not rebound when pressed down after the installation.

Air Traps occur easily in LSR injected silicone keyboard with button webbing. Air trap is that air get stuck in the mold cavity and can not run away from mold vents. Air traps always happen in the last-to-fill area and thick-to-slim area. Air traps in injection mold will cause defeects in molded parts, like voids and bubbles, short shoot also known as incomplete fill.
