The ceramic anilox roller is often referred to as the heart of the flexographic press. It is designed to deliver a precise and consistent amount of ink to the printing plate.
The latest chrome anilox roller is laser engraved, with cell counts currently up to 500 cells/cm, from a steel roller and coated in fine ceramic. These laser engraved ceramic rolls could last up to 10 years, depending on the wear they are exposed to from contact with the doctor's blade. They provide an even, and consistent ink delivery in a controlled manner and provide narrow web flexo with a competitive edge in the leading packaging markets eg self-adhesive labels fo
Some of today's servo driven narrow web presses make use of anilox sleeves, which are much lighter than the standard solid anilox. The advantage is ease of handling and loading. On the narrow web side there is no difference in performance than with a conventional roll. Ceramic anilox sleeves initially were profiled in a scenario of short-run environments where anilox changes are very common and required, but have shown their usefulness regardless of the frequency of changeover. Sleeves are easier to store and inventory.
The disadvantages of sleeves are their cost as well as the different care and handling that is required. Converters need to design special racks to store sleeves so that the chance of damage is minimized. In addition, sleeves cannot be cleaned in the same fashion as rolls, which may add more time and cost.
Mirror rollers are generally used in plastics, packaging, printing, steel and other industries. Since traditional hard chrome electroplating cannot fully meet the requirements of wear resistance and corrosion resistance, our matting rollers can perfectly solve these problems. Its hardness is increased from HRV800 with hard chrome layer to HRV1200, the corrosion resistance is greatly improved, and the service life is long.
Dr blade materials, on the other hand, are a little more complicated of a subject than that of their shape. There are five materials commonly used to create blades today and they are as follows: plastic (UHMW/UHMWPE), stainless steel, carbon steel, tool steel and graphite. While the steel blades have upsides and are favored by many within the industry, current trends and advancements in technology are heating up the playing field for plastic and graphite.
