Pad Printing Solutions: Types and Applications of Sealed Ink Cup and Doctoring Rings
When looking at the printing equipment market through platform in recent years, it is clear that the biggest change in equipment design and implementation has been the widespread use of sealed ink cup systems through systems inkwell open blade. A system of sealed ink cup is essentially and inverted cup that is filled with ink and used the sharp edge of the cup as a printing plate cleaning the system. In this system floods and doctors (wipes) a printing plate in the same motion, solvent evaporation and changes ink viscosity are much more limited than with blade systems, so that the cup sealed ink printing process much more predictable and manageable.
In the U.S. sealed cup systems market have dominated the purchase of new equipment for a number of years. This article discusses the types and applications of sealed ink cups and the advantages of ceramic rings care.
Almost all types of sealed ink cup can be divided into two categories, magnetic or nonmagnetic. Both styles of glass, when integrated into the pad printing machine with excellent cleaning results, properly handled printing plates.
A cup Magnetic Ink is basically "self-care unit." With its powerful magnets, it has everything necessary by force to clear the board that require the machine only has to pull back and forth. The magnetic ink cup in general, has found its strength in multi-color applications because the team in general can be of simple construction and multi-color pad printer more profitable.
magnetic ink cups are not designed to take pressure applied by the pad printing machine a flange or center hole in the cup. Pressure is applied by a spring system for mounting ink cup run. The system Spring is compact and very effective, but not so easy to implement in a multi-color machine. The non-magnetic cups seem to have a place in compact or high-speed applications of the machine. In these systems, even at high speeds, the spring retention system keeps the ink cup firmly in place while the plate in and out.
There has been much debate about what ring material is best for guard plates. We say that the market is divided between the carbide ring and the new generation ceramic ring guard. Nowadays, both carbide rings and ceramic rings work extremely well. In our view, however, that the guard ring ceramic has some advantages.
One of the main advantages of the ceramic ring has a "self-lubricating" qualities that make it work well well in the thin and thick stainless steel plates imprinted polymers softer. Carbide rings are generally quite strong and abrasive and will wear a badge polymer material quickly. Another advantage of the ring is to take care of ceramics generally thicker, more robust and resistant to damage from handling. Most taper ceramic rings from inside and outside diameter of a "point" about 0006 "leaving a lot of material about the tip. Carbide rings, however, taper from the outside diameter of up to a point "with a cross section of 0.003", leaving only a minimal amount of material near the tip that results in more damage during handling of the operator. The combination of the profile of the ring and the fragile nature carbide to repair the damage to the rings quite common during normal use.
In general, the quality of the products on the market have pad printing become very high, so that regardless of the type of sealed ink cup or ring of material that is required to have an experience of great success.
