benefits of polishing

 Why to polish press tools?



Polishing of tabletting tools is necessary to keep the quality of the pressing surfaces (tips).


By polishing we can enhance the roughness of the pressing surfaces and eliminate the tendency of the tablet to stick.


Smooth surface of a tip reduces friction during tabletting, when punch rotates during compression (round tablets).


Smooth surfaces of the punch shaft can reduce the punch tightness in tablet presses


Cleaning of polished punches is easier and more effective
