Case Study: Controlling Motion in Consumer Electronics
Background
Controlling the ease of motion is often a challenge when designing and maintaining a quality electronic design. Motion control grease, also known as damping grease, is often a cost-effective solution to dampen motion while reducing noise and vibration. One of Nye’s affiliates was contacted by an electronic maintenance company in search of a motion control grease that would replace a discontinued lubricant they had been using. They needed to lubricate the spring mechanism that released the scanner’s lid to slow the motion and prevent the device from closing too harshly.
Challenge
-
Can Nye provide a stiff damping grease that will slow the closing of the heavy scanner cover?
Solution
PG-44A
A silica soap thickened, heavy viscosity, synthetic hydrocarbon grease
- Extremely stiff and tacky grease
- Slows motion
- Eliminates noise, vibration, and harshness
- Provides a quality feel for user
| Product | Chemistry | Temperature Range |
Viscosity (40°C) |
Oil Separation (24hrs @ 100°C) |
|---|---|---|---|---|
| PG-44A | Polybutene/Silica | 20 to 120°C | 192000 cSt | 0.0 |
Results
Nye's affiliate recommended that the company use PG-44A from Nye’s line of motion control greases. PG-44A gave the desired level of damping to the scanner cover and customer was extremely satisfied with the results. The feed table release/drop motion became a controlled action and helped improve the perceived value of the refurbished device.
