Dimensional Tolerances Guide for Silicone Molded Parts
Tolerance tables provided by the Rubber Manufacturer’s Association (RMA) come with ranges to illicit communication between the user and provider over a wide array of industries. It can be noted that precision tolerance can be achieved by utilizing the manufacturing process. In contrast, some mis-specified tolerances more often than not lead to irrelevant expenses. As…
DetailsDesigning Your Custom Keypad: Actuation Force and Snap Tolerance
One of the main decisions that you will make when designing your keypad is how you want your keys to feel when they are pressed. Silicone keypads are extremely versatile and Silicone Dynamics can produce keypads ranging from extremely sensitive to extremely tactile. Reasoning and Analysis Actuation force is important for keypads, giving the user…
DetailsDesigning Keys for Custom Rubber Keypads
When you are producing a custom silicone keypad, pay careful attention to the way that your keys will be labeled or marked. Many keypad designs do not require marking, such as keypads that will be held in place by a (labeled) bezel of some kind. However, most keypads need some form of marking to identify…
