Causes and treatment of explosive punch of tablet press

The causes and treatment of detonation are as follows:

Punch burst and missing Angle, metal chips may be embedded in the tablet. Due to improper heat treatment of the punch, it has damage and cracks without careful examination, can not withstand pressure or too much pressure of the tablet press, and can cause explosive impact when pressing crystalline drugs. The heat treatment method of punch should be improved, the quality of punching die should be checked, the pressure should be adjusted, and the appearance of tablet should be checked. If a detonation is found, the debris should be searched immediately and the cause identified to overcome it.

The causes and treatment of the fault thrust are as follows:

Fracture of punch or punch neck. Due to improper heat treatment of the die, there are damage cracks in the die without careful inspection, the pressure of the press or the tablet press is too large, and the fatigue limit of the die itself can be caused by the break punch. The heat treatment method of punch should be improved, the quality of punching die should be checked, the pressure should be adjusted, and the appearance of tablet should be checked. At the same time, the service life of the die can not be unlimited. Generally, it should be scrapped when it is 30-50 million pieces. It can not be replaced to save money. The upper punch punch is easy to hit the feeder, and the lower punch punch is easy to hit the punch track. The feeder or down thrust track will be damaged if a break occurs. Therefore, often check the mold and replace the old mold in time.

In addition, a breaker protection device can be added to the equipment to protect the feeder and track in case of a breaker, so as to avoid being damaged and causing greater losses.
