How To Extend The Service Life Of Rotary Tablet Press Molds?

Different types of rotary tablet presses have different molds and different scopes of application, but they usually encounter the same problem, that is, splitting.

Then why does the rotary tablet press die crack?

The main reason is that there are too many fine powders in the granules. When compressed, there is air in the particles. Faster compression and tighter punch-to-die clearance. When compressed, the air is not excluded from the particles, but rather enclosed in the flakes. When there is no pressure, the air expands, which will cause debris.

When using the rotary tablet press mold, pay attention to the maintenance of each part of the tablet press. In some parts, lubrication is required to help this rotary tablet press die extend its working time and life.

1. Clean the tableting room in time. After the rotary tablet press mold has been working continuously for several hours, the tablet press cavity will be filled with fine powder of the material. These fine powders adhere to punches, punching holes and middle die holes, which can cause plug punching, inflexible punch rotation, noise, and even unstable tablet weight and other mechanical failures, such as punch breakage, feeder breakage, etc. Therefore, the tableting room should be cleaned regularly during the working process, and it is recommended to clean it at least once per shift.

2. Regularly inspect and maintain workpieces that are prone to wear. Guide rails, rollers, rotary tablet press molds and other wearing parts. It should be checked or lubricated in time, and preventive maintenance of the equipment should be carried out.

3. Purchase spare parts. Stamping die, middle die top wire, bridge plate, feeder, guide rail components, upper and lower pressure rollers, shafts and other components. A certain number of spare parts should be purchased according to the production situation for emergency use.

At present, when maintaining the tablet press, we should also pay attention to increasing the maintenance frequency of the parts. Pay attention to the maintenance of the rotary tablet press mold. In some places, lubrication can help the tablet press to work longer and last longer.
