Liquid Silicone Keypad Over-mouldings

Using Liquid Silicone moulding technology Rubbertech can now supply customers with complete keypad / plastic over-moulded assemblies.

Using Liquid Silicone moulding technology Rubbertech can now supply complete keypad / plastic over-moulded assemblies.

This offers high IP rated assemblies without the requirement for additional bonding processes that may not offer reliable sealing.

The plastic component is pre-moulded and then loaded into the LSR injection tool. Liquid silicone can be moulded at much lower temperatures than traditional silicone used for keypads and without the high compression forces.

Once the LSR and plastic are moulded they form both a mechanical and chemical bond.

The keypad assembly can then be finished with printing, spray coatings and laser etching processes as well as being assembled with flex circuits or switch layers.

If you would like more information on these mouldings or any other mouldings we can supply please get in touch.
