In general, pad shape can be almost anything imaginable, yet the most prominent configurations in use today are either conical, rectangle, square or “roof top” in appearance. There are over three hundred standard pad shapes in use, yet the vast majority are modified versions of these four basic profiles.
- Conical – Typically conical or round shaped pads are the most popular as their diameter allows them ability to print on virtually any surface be it round, flat, or irregular.
- Rectangular or Square – Rectangle or square pads are more often used when solely printing lines of copy or graphics on flat surfaces.
- Roof Top – generally used when a pad must be forced within a narrow geometric area such as the parting line of a semiconductor strip. Special pad shapes of custom pads should only be utilized if and only if the common shapes fail. Custom pads are usually more expensive than standard shapes.
Pad Durometer / Hardness
In addition to the shape, the durometer (hardness) of the print pad plays an equally important role.
Remember, as a rule of thumb; ” The higher the angle, the harder the durometer, the better the print.” However, substrate structure, tooling layout, and a myriad of other factors may not allow the use of a hard-pointed pad. To deal with these obstacles, lower angle pads are available. Also, durometer is adjustable. AccuPad can manufacture pads in the range of 20-80 Shore OO or anywhere in between with a plus or minus 3 range consistently, should that be your request.
By special request, AccuPad will design and produce a “dual durometer” print pad which as its name indicates has two different durometers in one pad or even a hollow pad for those extremely difficult applications.
We also have a wide range of colors if color is your preference, and any durometer can be any color:
- Blue, Gray, Pink, Lime, Green, Yellow, Orange
- Lavender, Bright Red, Dark Green, Beige/White, Red/Mauve/Rust
When ordering a Pad, please indicate which type mounting base you require. If unsure, please feel free to call or email us and we can help you determine the proper base and mounting requirements if needed.
