laboratory tablet pressThe powder granules can be compressed into tablets, which are widely used in pharmaceutical factories, chemical plants, hospitals, scientific research institutions, laboratories, trial production and small batch production. The powder tablet press has excellent performance, strong adaptability, convenient use and maintenance, small size, light weight, and can be shaken manually when there is no electricity. The filling depth and thickness of the powder tablet material can be adjusted to meet the requirements of the pharmaceutical industry for pressing various similar products. So what are the precautions for operating the laboratory tablet press?

What are the precautions for operating a laboratory tablet press?

Before use, check whether the specifications of the mold used are consistent with the required specifications. Before installing the mold, wipe it with a clean cloth and then wipe it with 75% ethanol. After ethanol volatilization, installation and use. During installation, pay attention to check whether the male and female dies are consistent. Pay special attention to handle with care. At the same time, be careful not to mix old and new molds. When necessary, the control and influence of weight differences should be evaluated or tested. Precautions for the use of laboratory tablet presses:

1. Regularly check whether the amount of oil in the oil pool reaches 3/4 (after the working piston is reset). If the height is not enough, open the screw of the oil injection hole and inject 46# hydraulic oil without impurities.

2. Regularly lubricate the small piston and its connection parts.

3. Tighten the oil hand wheel appropriately to prevent oil overflow and keep it clean.

4. When the working piston needs to rise to a certain height, pay attention to the working piston can not exceed 1/2. so as not to damage the parts.

The pressure of the machine should be less than 44Mpa(15 tons). Exceeding the limit can damage the machine or cause danger. Remind the operator not to overpressure.

6. When the new machine is not used for a long time, tighten the oil hand wheel before use and pressurize 20-25 MPa; That is, discharge, repeated use several times can be used normally.

7. When operating the machine, remove the sealing tape from the screw of the oil filling hole and use it normally.

8. The pressure plate needs to be installed on a workbench with sufficient strength. If necessary, it should be fixed on the workbench.

9. Before transportation/handling, please tighten the exhaust valve to prevent oil leakage.

What is the development history and current situation of laboratory tablet press?

1. The tablet press has many specifications and large quantities. The tablet press is an ancient pharmaceutical equipment in China, which can be used to press round thin plates, lettering thin plates, special-shaped thin plates, double-layer thin plates, multi-layer thin plates, ring thin plates and chip-coated thin plates. The number, variety, specification and output of tablet press manufacturers rank first in the world.

In recent years, tablet press manufacturers began to attach importance to product quality and believe in the business philosophy of "winning by quality. The developed tablet press product has the characteristics of simple operation and convenient cleaning, especially when changing varieties.

Low technical content and insufficient technological innovation. There are more than 40 pharmaceutical equipment enterprises in China, producing more than 60 kinds of tablet presses. Although new products are launched every year, there are few varieties with high technical level and high added value. Product duplication development is serious, plagiarism prevails. In order to survive, many small pharmaceutical equipment companies not only adopt a "imitation" strategy in technological innovation, but some manufacturers even rely entirely on copying other people's technology as their own technological innovation. In order to compete for orders, we often lower our prices. Due to the low brand loyalty, after the price war, these brands will suffer more losses, which will inevitably lead to the overall retrogression of China's tablet computer design and manufacturing level.

4. The vast majority of enterprises in China are private enterprises, which have no advantages in technology, equipment and talents, which seriously restricts the technological innovation of enterprises. Some enterprises lack research and development, the institutional innovation system is not perfect, the technical personnel lack the awareness of technological innovation, the overall technical strength of enterprises is not strong, and the speed of updating scientific research and production technology and equipment is very slow. It is worth noting that the entire industry of science and technology talents are in the "no contact" stage. It can be said that the talent crisis is spreading throughout the industry.
