Storage and Maintenance of Dies for Powder Press

Storage and Maintenance of Dies for Powder Press

The significance of the storage and maintenance of the die: in the pharmaceutical production process, the die for pressing tablets plays a vital role in the quality of tablets, such as the punch hole becomes larger, resulting in uneven filling of punching holes, resulting in the discrepancy of tablet weight or fragmentation; the length of punch body varies, directly affecting the discrepancy of tablet weight and hardness, causing fragmentation, or affecting the fragility; the punch has a kowtow edge and curling edge. Or the punch is not even, affecting one-sided cause cracks, stick punching and so on. Therefore, in the daily management, we must pay attention to the daily maintenance, maintenance and storage of the powder tablet press die, in order to ensure the quality of our tablets.

The following procedure is hoped to be helpful for the daily maintenance, maintenance and storage of the powder tablet press die in the future.

1. The newly purchased moulds shall be accepted and accepted by workshop mechanics, and the qualified moulds shall be submitted to the head of the pressing team for further confirmation.

2. After receiving, it is necessary to remove the outer package, clean and disinfect with 95% ethanol after removing the rust-proof oil, so that it can be stored in the mould room for use. When storing, it should be placed in the area according to the machine type and sheet type, and at the same time, it should be marked clearly.

3. Before using, check whether the specifications and models of the mould used are in conformity with the required specifications and models. Before the die is installed, clean cloth is used to wipe, then 75% ethanol is used to wipe. After the ethanol is volatilized and cleaned, the machine is installed for use. In the process of installation, attention should be paid to checking whether the punch and the die are in accordance with each other. Special attention should be paid to light handling and light handling. At the same time, attention should be paid to not mixing the old and new dies. The control and influence of sheet weight difference should be evaluated or tested when mixing the old and new dies.

4. Mould should be sent back to the mould management time and cleaned in time. 95% ethanol should be used when cleaning. During the cleaning process, attention should be paid to checking whether the mould is damaged, picking out the damaged ones in time, repairable ones should be repaired, and those who can not be repaired should be evaluated, scrapped and registered by workshop mechanics.

5. If the cleaned mould is not used for a long time, it should be coated with a layer of rust-proof oil. When it is stored, it should be placed in the area according to the machine type and sheet type. At the same time, it should be marked clearly. Storage process should ensure the room temperature and humidity to avoid mould rust. If the room humidity is too high, the dehumidifier can be opened to keep dry, keep the mould room clean and dry, and the mould room should not store anything other than the mould.
