Our ceramic ring is made from zirconia (ZrO2, 3Y-TZP).

 The zirconia ceramic printing squeegee cutting ring is the imported powder isostatic pressing after precision grinding processing, high hardness reached 90HRA. 

It has the incomparable advantage than ordinary steel ring:

1. Zirconia ceramic wear resistance is very high, the wear life is more than ten times . its hardness is six times as ordinary steel, twice as carbon steel, and the smoothness of the surface of the product is very high, low coefficient of friction, so the life of the ceramic the incision cup ring much longer life than steel knife cup ring.

2. A small coefficient of thermal expansion of the zirconia ceramic, high temperature, Because of the continuing frictional heating of the ring will not result in product damage, deformation, change the incision accuracy affect the printing quality.

3. Due to the metal ring is easy to release the metal ion, with the ink chemical reaction occurs, affecting the quality of the color of the ink.

Also easily oxidized to form a metal fine crumbs mixed into the ink to affect print quality.

Zirconia ceramic ring chemical stability, however, acid-resistant, high temperature, wear-resistant, anti-oxidation, anti-magnetic, electrostatic, and good self-lubricating properties will not affect the printing quality.

In summary, ceramic ring knife is the ideal alternative steel ring knife.

Outer diameter up to 250mm. Edge breadth could be 0.1mm; SS-DB, SS-SB, DS-SB, and DS-DB structure can be provided. Thickness could be less than 3mm; special size & structure and customer design are welcomed. Ceramic ring repair service also provided.

Printing machine ceramic ring : 95% zirconium porcelain , 99% zirconium porcelain ; 
Zirconia ceramics with high hardness, good wear resistance, high toughness , low coefficient of friction , good corrosion resistance , etc., are widely used in mechanical seals ( eg : close ink cup pad printer cutter ring ) , milling media , cutting tools , ceramic bearings, automotive engine parts, machine dewatering equipment, the main production of cutting tools, all components within the engine , containing molten steel equipment, military , aerospace parts and other high-tech applications -resistant parts, wear-resistant parts, corrosion resistant parts . 

Zirconia ceramic ring wear is 15 times alumina ceramic ring. Density printing machine zirconia ceramic ring is 6 , a more delicate texture , after grinding , the surface finish higher up than 9 , showing a mirror -like, very smooth, the coefficient of friction smaller. Higher surface finish , showing a mirror -like, very smooth, the friction between the plates is smaller, the service life of the steel sheet can be further increased , greatly reducing the loss cliches plate . Further toughness zirconia ceramic ring and excellent overcome the inherent brittleness of the ceramic , high wear resistance, greatly extend the life of the product , cliches plate life is significantly improved.
