Ink Cup Ring Product Introduction
The ring (ceramic or tungsten carbide) is a component of the pad printing ink cup. Due to prolonged doctoring against the cliché, the ring wears out over time and requires replacement. The ring is a consumable part in pad printing machines.
Differences Between Ceramic and Tungsten Carbide Ink Cup Rings
Ceramic Ink Cup Rings:
It is made of zirconia, which is abrasion-resistant. It’s not as hard as tungsten carbide, but it costs less than a tungsten carbide ring. So, the ceramic ring is the standard ring used in the cup for most pad printing users.
Tungsten Carbide Ink Cup Rings:
It provides high abrasion resistance and excellent hardness. So, for long-term use, some pad printing machine users choose this type of ring. But it costs slightly more than the ceramic ring.
Ink Cup Ring Specification:
The rings (both ceramic and tungsten carbide) have the following specifications:
Blade Types
- Single-blade: The ring has a blade on only one side.
- Double-blade: The ring has blades on both sides.
Bevel Types
- Outside bevel: Beveled from outer to inner, forming the blade edge.
- Inside bevel: Beveled from inner to outer, forming the blade edge.
- Double bevel (inside and outside): Beveled from both inner and outer to the middle, forming the blade edge.
Ring descriptions usually consist of two parts, such as “single blade, outside bevel” or “double blade, inside and outside bevel.”
