In this comprehensive guide, we will explore the technical brilliance, structural advantages, and unparalleled efficiency of this Fully Automatic Pharmaceutical Tablet Press.
A Leap Forward in Tablet Press Technology
The GZPK-660 series represents a massive evolutionary step in pharmaceutical manufacturing. We originally based our design on the highly respected British Manesty technology from the 1990s. However, our engineering team did not stop there. We continuously innovated and refined the mechanics.
Today, our machine offers higher automation, better operability, faster production speeds, and far superior stability compared to standard market offerings.
Many domestic competitors still rely on outdated single-discharge 1980s technology or basic Fette clones. Our GZPK-660 series breaks the mold. We deliver a true double-discharge High-Speed Automatic Tablet Press that minimizes running noise while maximizing your output. It currently stands at the leading edge of domestic and international technology.
The Power of the Double-Discharge Mechanism
Efficiency drives profitability. Our machine features a highly optimized double-discharge mechanism.
For every single rotation of the turret, the machine completes two full cycles of filling, pre-pressing, main pressing, and tablet ejection. This dual-action design intelligently utilizes every station on the left and right sides of the machine. You effectively double your production capacity without increasing the footprint of the equipment.

Optimal Working Conditions and Applications
We designed the GZPK series to handle a wide variety of materials. It thrives in the pharmaceutical, chemical, food, electronic, and metallurgical industries.
You can effortlessly press various granular raw materials into round tablets, irregular shapes, cartoon-shaped tablets, and double-sided engraved tablets.
Ideal Granule Specifications
To achieve the best results, you must feed the machine the right materials.
For synthetic starch granules, ensure the granules remain uniform and dry. The proportion of fine powder (above 60 mesh) should never exceed one-third of the total volume.
For traditional Chinese medicine granules (full extract, semi-extract, or raw powder), the material must remain dry and possess good fluidity. The machine easily handles granule sizes ranging from 12 to 60 mesh. You can also utilize this machine for direct dry powder compression.
Please note that this high-speed equipment does not suit semi-solid, moist, or extremely fine powder (greater than 100 mesh).
Environmental and Power Requirements
To maintain peak performance, operate the machine in an environment with a temperature between +10℃ and 35℃. Keep the relative humidity below 85%. You must store the equipment in a well-ventilated, dry place shielded from rain.
The machine requires a robust 380V, 50Hz, three-phase five-wire power supply. The neutral (N) and protective earth (PE) wires must remain isolated to prevent interference. The total power consumption runs at approximately 20 KW.
Mastering the Working Principle
How does this Fully Automatic Pharmaceutical Tablet Press achieve such incredible precision? The secret lies in our flawless mechanical choreography.
The pressing assembly consists of the turret, upper and lower punches, dies, pre-pressure rollers, main pressure rollers, left and right filling devices, and intricate cam tracks.
The Step-by-Step Pressing Cycle
The process begins as the turret rotates clockwise.
First, the punches enter the filling stage. The upper punch rises to bypass the forced feeder. Simultaneously, the pull-down cam pulls the lower punch downward. This creates a precise cavity inside the die. The forced feeder’s impellers actively push the granular powder into this cavity. We intentionally create an overfill as the lower punch reaches its lowest point.
Next, the machine moves to the metering stage. The lower punch gradually rises as it moves over the metering cam. It pushes excess powder out of the die cavity. A metering scraper clears away the surplus material, ensuring every single die holds the exact same volume of powder. A cover plate securely holds the powder in place until the upper punch descends into the die.
The Compression Phase
Once metered, the punches travel between the pre-pressure rollers. Here, the machine applies initial force to remove trapped air from the powder bed.
Immediately after, the punches pass between the massive main pressure rollers. The machine applies up to 100 KN of force to compact the material into a solid, flawless tablet.
Finally, the ejection cam pushes the lower punch upward while the upper punch retracts. The machine smoothly ejects the finished tablet into the discharge chute. Because we use a double-discharge structure, this entire process happens twice per revolution.
Advanced Structural Engineering
We build the GZPK-660 series to withstand the relentless demands of a 24/7 production cycle.
The main frame consists of a heavy-duty base plate, robust front and rear pillars, a worm gearbox, and an upper top plate. We bolt these components together to form an incredibly rigid structure. This framework offers outstanding resistance to bending and torsion.
We install column-type tension sensors inside the support pillars. These sensors constantly monitor the pressure applied by the rollers. We also surround the pressing chamber with four transparent acrylic doors. These doors feature heavy-duty telescopic latches that provide secure locking force while allowing operators easy access for cleaning and maintenance.
Precision Main Drive System
A powerful 11 KW AC motor drives the heart of the tablet press machine.
We employ an advanced frequency converter to manage this motor. This allows you to adjust the production speed seamlessly and continuously. The frequency converter saves energy, reduces mechanical shock, and ensures remarkably quiet operation. It also features built-in protections against over-voltage, low voltage, and over-current scenarios.
The motor transfers power through a synchronous toothed belt. This belt eliminates slippage and drastically reduces operational noise. The belt turns the worm gear reducer, which features a four-start worm for a high reduction ratio and massive torque. We precision-grind the worm and gear to a strict Grade 6 accuracy.
Intelligent No-Handwheel Design
We eliminated the traditional, cumbersome handwheel for adjusting parameters. Instead, we integrated a sophisticated synchronous motor control system.
You control the main pressure and filling depth directly from the digital touchscreen. The system provides real-time display values, giving you absolute, pinpoint control over your production metrics.
High-Efficiency Forced Feeding and Rejection Systems
Gravity alone cannot feed a High-Speed Automatic Tablet Press.
We equip our machine with a high-performance forced feeding system. An independent motor drives a turbine reducer, which spins dual impellers inside the feeder housing. These impellers forcefully and consistently pack the granules into the die cavities. We design the feeder base to sit perfectly flush against the turret surface, preventing material leakage and maximizing your yield.
Uncompromising Quality Control
You demand perfect tablets, and our machine delivers. We guarantee an average tablet weight control accuracy within ±2% (based on a 20-tablet sample).
To manage outliers, we offer an intelligent rejection system. The machine continuously monitors the pressure of every single punch. If the control unit detects a pressure spike or drop that indicates an incorrect tablet weight, it instantly takes action.
You can equip the machine with an optional single-tablet rejection system. This system fires an actuator to blast the individual defective tablet into a separate waste channel. Standardly, the machine includes a batch rejection valve that redirects the flow to the waste bin until the parameters stabilize.
Comprehensive Lubrication and Hydraulic Systems
Friction destroys machinery. We conquer friction using four distinct, highly engineered lubrication systems.
First, a continuous circulation filtration system lubricates the transmission gears and the main shaft.
Second, an intermittent micro-flow thin oil system precisely lubricates the upper and lower punch bodies.
Third, an electric dry oil system automatically greases the heads of the punches.
Finally, a manual dry oil system allows you to easily maintain the heavy-duty bearings on the main and pre-pressure rollers.
Hydraulic Overload Protection
Safety remains our top priority. We utilize a block-style hydraulic system to support the pressure rollers and provide instant overload protection.
If an operator feeds an un-compressible object into the machine, or if the pressure exceeds safe limits, the system reacts in milliseconds. The hydraulic oil in the main cylinder flows back into a nitrogen-charged accumulator. This allows the pressure roller to lift immediately, preventing damage to the punches, dies, and turret. Once the obstruction clears, the system automatically resets to its normal working state.
Superior Dust Control and Cleanability
A clean machine runs better and lasts longer.
We designed a unique, highly effective dust collection system for the GZPK-660. We enclose the upper pressing zone with specialized U-shaped dust covers and transparent acrylic shields. This creates a fully sealed upper chamber. The positive air pressure inside this chamber completely prevents dust and powder from contaminating the upper punches.
For the lower section, we utilize convenient push-pull dust covers. An operator can quickly slide these covers off for fast, thorough cleaning. This protects the lower punches from abrasive powder buildup, extending the lifespan of your tooling.
Smart Electrical Control and GMP Compliance
We built the electrical system around a top-tier Siemens S7-200smart Programmable Logic Controller (PLC).
This powerful brain connects to analog modules and remote data interfaces. Operators interact with the machine through a vibrant, responsive 10-inch Siemens color touchscreen. We exclusively use internationally recognized brands for all executing components to guarantee maximum reliability.
The software interface provides intuitive pages for production monitoring, parameter configuration, alarm history, and individual punch pressure tracking. If a fault occurs, the system triggers an immediate alarm, stops the machine, and displays a clear diagnostic message on the screen.
Strictly Adhering to GMP Standards
We manufacture the GZPK-660 to strictly conform to Good Manufacturing Practice (GMP) requirements.
We never use paint or electroplating on any moving parts inside the pressing chamber. We construct every single component that contacts the pharmaceutical product—including the turret, feeder base, discharge chute, and cabinet covers—from premium stainless steel. We manufacture the pressure plates from high-grade PTFE. This ensures your production environment remains perfectly sanitary and safe.
