Today, tablet presses are no longer confined to the suppression of Chinese and Western medicine tablets, but they can also be widely used to suppress health foods, veterinary medicine tablets, and chemical tablets: such as camphor balls, washing blocks, blue wizard blocks, art powders, and pesticides. Tablets, etc., food tablets: chicken essence, Radix isatidis, Divine Tea, compressed biscuits, etc.
Tablet presses appeared early in European and American presses and have a history of nearly one hundred years. In China, by the year 1949, the Tianji Huaji ironworks in Shanghai mimicked an English-style 33 stamping machine; in 1951, it was converted into a domestically-made 18 stamping machine according to the United States 16 stamping machine, which was the earliest domestic manufacture of pharmaceutical machinery. In 1957, ZP25-4 tablet press was designed and manufactured. In 1960, the 60-30 tablet press was designed and manufactured by itself. It has the functions of automatic rotation and tablet pressing. The tablets are compressed in tablets, sugar tablets, and calcium tablets. , coffee tablets and so on. In the same year, ZP33 and ZP19 tablet presses were also designed and manufactured. With the increase in the level of manufacturing processes, automation control technology, and various special requirements for tablet press manufacturers, various special-purpose tablet presses have emerged.
Analysis of Problems in Tablet Press in China (1) There are many specifications and large quantities of tablet presses. The tablet press is the pharmaceutical equipment with the longest production history in China, as well as the pharmaceutical equipment with the earliest export and the largest output. According to incomplete statistics, there are nearly 40 manufacturers of tablet presses in China with a production volume of nearly 2,000 units/year and 60 product specifications. They can be used to suppress round pieces, engraved films, special-shaped films, double-layer films, multi-layer films, and circular patterns. Tablets, chips, and other chip types. It is an indisputable fact that the number, variety specifications, and output of tablet press makers rank first in the world.
(2) The operation is simple. In recent years, the manufacturers of tablet presses have begun to pay attention to the quality of products, and most of them believe in the business philosophy of “winning by qualityâ€. For domestic pharmaceutical manufacturers, a wide range of tablet varieties, small-scale production characteristics. The tablet press manufacturing company has developed a tablet press product that is characterized by simple operation and convenient cleaning. In particular, when the product is changed, the clearing is quick and convenient.
(3) Low technical content and insufficient technical innovation. At present, more than 40 pharmaceutical equipment manufacturers in China produce more than 60 types of tablet presses. Although, new products are being introduced every year. However, few of them have high levels of real technology and high added value. Repeated development of products is serious, and plagiarism is prevalent, and there are as many as a dozen tablet machine manufacturers. In order to survive, many small-scale pharmaceutical equipment companies not only adopt "imitation-type" strategies in technological innovation, but some manufacturers even rely solely on plagiarism of other people's technologies as their own technological "innovations," and some even "shrink". In order to compete for orders, price reductions are often adopted because of low brand loyalty. After the price war is played, these brands are even more disadvantaged. Now the brand is constantly devaluating. If this situation is not reversed, it will surely lead to an overall backwardness in the design and manufacturing level of China's presses.
The large gap between domestic and foreign presses has highlighted the fact that the vast majority of companies in China are privately-owned enterprises, and they do not have the advantages in technology, equipment, and talent, which seriously restricts their technological innovation. Some companies lacked R&D institutions, the innovation system was not perfect, technical personnel lacked awareness of technological innovation, the overall technical strength of the enterprise was not strong, and the pace of scientific research, production and technical equipment updating was very slow. What is most noteworthy is that the entire industry's scientific and technological talents are in a stage where "green and yellow are not connected." It can be said that the talent crisis is spreading throughout the industry.
At present, the development direction of foreign tablet press technology is intelligent, flexible, precise, and meets the requirements of GMP, and the product's high and new technology content has been continuously improved. The automation technology, numerical control technology such as mechanical, pneumatic, liquid, optical, magnetic, etc. Sensor technology, new material technologies, etc. are widely used in tablet presses. Most tablet presses in the country are open or not completely closed. The breaking process causes the dust between the tablets to fly. With the in-depth implementation of GMP, the tightness of the sheeting process and the isolation of people flow and logistics are particularly important. This is the basic function that we must have in designing, manufacturing and manufacturing equipment.
In fact, many companies have already seen the gap before the tablet press with foreign developed countries. Therefore, automation, large-scale and advanced detection technologies have become China's major development direction. In order to catch up with foreign countries in terms of speed production, domestic press machines need to have considerable development in the aspects of design innovation, processing technology, and automatic control of presses.
