Daily maintenance and maintenance skills of tablet press machine die in pharmaceutical field

Tablet press is a kind of pharmaceutical processing equipment, which is suitable for pharmaceutical tablet forming in tablet form. In the production process of tablet medicine, tablet press die plays an important role in product quality.

For example, the hole of the rotary tablet press punch becomes larger, resulting in uneven punch packing, resulting in the product weight difference is not in accordance with the requirements or produce lobes; The impact length is different, which directly affects the weight difference and hardness of the product and causes the fragmentation, or affects the fragility; Punch has knock edge roll edge or punch is not flat, the influence of one side cause slipper, adhesive and so on. Therefore, before the use of the mold needs to pay attention to the inspection and necessary maintenance or replacement, to ensure the stability of product quality and continuous lamination production, reduce the cost of the enterprise.

In addition, after the installation and use of the powder tablet press mold, it is necessary to check and maintain, to ensure the next use of the equipment in good condition. Therefore, in the daily management, operators must pay attention to the daily maintenance, maintenance and storage of the press mold, in order to ensure the quality of products. In this regard, the press machine equipment manufacturers Shared the daily maintenance and maintenance skills of the press machine mold, mainly divided into five points, only for reference in the industry.

First, if the pharmaceutical manufacturing enterprise newly purchased fully automatic tablet press mold, need to let the tablet press mold by the workshop mechanical personnel to receive and acceptance, qualified after the delivery of the tablet team leader to confirm again. Under the condition of ensuring stable operation of the equipment, it can only be put into production and use.

Second, it is important to pay attention to the storage of equipment. After receiving the equipment, the mechanical staff of the workshop shall remove the outer packing, remove the anti-rust oil, and clean and disinfect it with 95% ethanol before storing it in the mold for later use. The storage shall be arranged according to the model and the tablet type, and shall be marked clearly at the same time.

Third, before using the tablet press mold, it is necessary to check whether the specifications and models of the pharmaceutical tablet press mold are consistent with the required specifications.

Before installing the mold, wipe it with clean cloth, then wipe it with 75% ethanol, and then install it for use after the ethanol volatilizes. The industry reminds that in the process of installation, should pay attention to check whether the punch and the die match, pay attention to handle gently, at the same time, pay attention to the old and new mold should not be mixed, have to be mixed to evaluate or test the control and influence of the difference in piece weight.

Fourthly, the pharmaceutical tablet press molds shall be sent back to the mold management room after use and cleaned timely. 95% ethanol shall be used for cleaning. During the cleaning process, attention shall be paid to check whether there is any damage to the molds.

Fifth, after cleaning, if the fully automatic rotary press mold is not used for a long time, it should be coated with a layer of anti-rust oil, according to the type of storage and plate type placement area, at the same time with an obvious label.

It is recommended in the industry that the storage process should ensure the temperature and humidity of the room, in order to avoid the pharmaceutical press mold rust, such as the room humidity is too large can open the dehumidifier to keep dry, keep clean and dry between the mold, mold shall not be stored in addition to any items outside the mold.
