Over molding also called as double molded process， co-molded process Silicone Rubber Keyboard which need different colors keys， but don't want the colors mixed.In this state， over molding process is one of the choice.Rubber Keypads and Keyboard， Rubber Keypads ,Custom Rubber Keyboard ,Custom Rubber Keypads ,Silicone Button Pad.
Over moldings lic one rubber keyboard is achieved by a double-shot process.To mold the desired colors keys firstly.Generally， they should be molded in a harder durometer
And then the molded keys will be positioned in a special insertion tool.The insertion tool is used to push the molded keys into the main tool.
Then， the silicone rubber button pad in the mold will bond and permanently vulcan ize to the keys.Advantage-Multicolor Silicone Rubber Keyboard by over molding have beautifullooks
， without any mixed colors.
Rubber keypads are made using compression mold tooling. Compression molds have a bottom tool and a top tool (think of a waffle iron). First, the mixed raw silicone material is cut into precise cut slabs. The material is then laid into the mold set. Pressure, heat and time are used to transform the material to the shape of the cavity. The parts are removed from the tool, flash is hand torn and then the parts are post-cured to remove any residual catalyst material.
The rubber keypad has a conductive ring or conductive carbon pll on the bottom.When the rubber is pressed from above， the conductive ring,carbon pills or other conductive pll contacts the PCB and then closes the circuit The effect is completed.These switch contacts are extremely simple，which means they are cost-effective and very durable.Unlike many other input devices the effective life of a silicone keypad is effectively infinite.The conductive contact can be different ways：1.Conductive Ink printing 2.Electric Conductive carbon pills.3.Metal Dome.4.Conductive Golden Pill.5.Nickel Pills.
