dental machine history
Tablet press tablet press appeared in Europe earlier, there are nearly a hundred years of history. In China in 1949, Shanghai Tianxiang Hua Kee Iron Works imitation caused British 33
Punch tablet press; 1951, according to the U.S. 16-punch tablet machine converted into a domestic 18-punch tablet machine, which is the earliest domestic manufacturing pharmaceutical machinery; 1957, designed and manufactured
ZP25-4 type tableting machine; dental material 1960, to design and manufacture successful 60-30 type tableting machine, with automatic rotation, compression function, pressed varieties tablets, sugar tablets,
Calcium, coffee tablets. The same year also design and manufacture a type ZP33, ZP19 type tabletting machine.
In the 1970s began Shanghai Daiichi Pharmaceutical Machinery Factory (Shanghai Tianxiang's predecessor) and Shandong Medical Instrument as compression tableting machine tablet press sentinel manufacturers large
Production ZP series tablet press. "Plan" period, the Department of Aerospace 206 HZP26 successfully developed high-speed tablet presses. In 1980, the Shanghai Pharmaceutical Machinery Factory first system designed to
Made the ZP-21W type tableting machine, to the early 1980s the international advanced level, is the first domestic product. 1987, the introduction of the Federal German Fette company microcomputer control
Manufacturing technology, design and manufacture of P3100-37 rotary tablet press with automatic control tablet weight, pressure, automatic digital film, films and other features automatic elimination of waste, closed
Structured, the degree of purification to GMP requirements. 1997, the annual Shanghai Pharmaceutical Machinery Co., Ltd. Tianxiang Kin developed ZP100 series rotary tablet press, GZPK100 Department
Column speed rotary tablet press.
In the 21st century, with the deepening of GMP certification, in full compliance with the GMP ZP series rotary tablet machine have appeared: Shanghai's ZP35A, Shandong Liaocheng ZP35D
And so on. High-speed rotary tablet machine production, the pressure signal acquisition and rejection and other technology has been developed rapidly, the highest yield is generally greater than 300,000 / hour, the most
Large pre-pressure 20kN, 100kN maximum principal stress 80kN or more. For example, the Beijing Science and Technology Co., Ltd. Sinopharm Long Li GZPLS-620 Series High Speed Rotary Tablet Press,
Shanghai Tianxiang Jian teeth whitening machines Pharmaceutical Machinery Co. GZPK3000 series high speed rotary tablet press, Beijing Aeronautical Manufacturing Technology Research Institute, PG50 Series High Speed Rotary
Sheet machine.
With the level of manufacturing process technology, automatic control technology to improve and tableting machine manufacturers use a variety of special needs, a variety of special-purpose tablet press
Have also emerged. For example, laboratory ZP5 rotary tablet machine for dry powder tabletting rotary tablet press machine for gunpowder explosion-proof ZPYG51 series tablet
Rotary tablet machine.
