*Silicone rubber keypad
*Application: electronic equipment for refrigerated control systems
* - Non-conductive keypad *-Conductive keypad(w/ black conductive particles)
- 5mm black conductive particles
*- Production workflow 1
- 4mm black conductive particles
*- Production workflow 2
- 4mm black conductive particles
1x4 cavities
*Only the printing fixture is not ready yet, so printing position looks not precise enough
*The test hardness of original keypad sample at Shore A 52, the actual hardness of keypad samples Shore A 50.
*The keypad sample is slightly bigger, it creates some friction inside the plastic enclosure, unlike the original keypad. Some silicone rubber need be reduced by tooling modification.
*the color of 2nd time samples are close to original keypad
The succeeding batches of Keypad, color as last time samples, black wording print as original sample, exact position and complete.
