Many customers will break the upper punch of the tablet press when using the tablet press. In fact, most of the time, it is not the quality of the tablet press that is not good, but due to improper operation or failure to clean up garbage in time. Shanghai Tianhe Pharmaceutical Machinery Co., Ltd. will introduce you to six common reasons:
First, the punching dirt on the tablet press end is too much or the upper punch is insufficiently lubricated, and the upper punch is too difficult to lift, resulting in the punch breaking;
Second, when pressing tablets, the pressure is too large, resulting in the instability of the pressure bar, the punch fracture;
Third, the rail production is too rough, burrs and other defects too much;
Fourth, the upper punch itself has cracks during heat treatment, and the punch is broken along the original cracks when the tablet press is working;
Fifth, the punch itself processing accuracy is too low, coaxiality error is too large;
Sixth, the punching coaxiality error of the upper punching plate and the middle punching plate is too large.
