The multi punch rotary tablet press is a miniaturized machine based on the automatic rotation and continuous tablet press used in production. It is mainly used for process research in industrial sectors such as pharmaceuticals, chemicals, food, and electronics, and is an important equipment for confirming whether granular raw materials can be compressed into tablets.

The difference between multi punch rotary tablet press and single punch tablet press mainly lies in their working principle, output, tablet weight difference, tablet appearance quality, and ease of operation. Below, the editor will briefly introduce to you:

working principle

Single stamping sheet machine: The single stamping sheet machine uses a cam linkage mechanism to generate relative motion between the upper and lower stamping sheets to press them. This design results in uneven pressure on the upper and lower sheets of the single stamping machine during compression, which can easily lead to problems such as looseness and cracking.

Multi punch rotary tablet press: The multi punch rotary tablet press is equipped with multiple pairs of circular dies on the working turntable, and the tail of the upper and lower punches is controlled by a fixed lifting guide rail. When the turntable rotates, the upper and lower punch heads and the middle die continuously rotate around the axis, while the upper and lower punch heads move vertically along the trajectory of the upper and lower tracks, completing the process of filling, pressing, and discharging.

Differences in yield and wafer weight

Single stamping machine: Due to uneven pressure and significant differences in tablet weight, the output is relatively low, and the quality control of tablets is poor.

Multi punch rotary tablet press: Due to simultaneous upward and downward pressure, the pressure is uniform, the difference in tablet weight is small, the output is high, the appearance of the tablets is good, and there is less layering of light and heavy particles.

Tablet appearance quality and ease of operation

Single stamping machine: Due to uneven pressure, it is easy to produce loose pieces, cracks, and other problems. The uneven pressure on the upper and lower parts of the tablet can easily cause top cracking.

Multi punch rotary tablet press: uniform pressure, low vibration, fixed scraper, less layering of light and heavy particles, more accurate tablet weight, and good appearance quality of tablets. In addition, the weight and thickness of the multi punch rotary tablet press can be precisely controlled through an adjusting device, making it easy to operate.
