Product Overview

Precision rotary compression for pharmaceutical-grade tablets

The ZP Series Rotary Tablet Press Machine represents state-of-the-art tablet compression technology designed to meet the stringent requirements of modern pharmaceutical manufacturing. Our fully automated rotary presses integrate powder feeding, pre-compression, main compression, and tablet ejection into a seamless, high-throughput workflow.

With production capacities ranging from 50,000 to 400,000 tablets per hour across 5 to 55 stations, our equipment serves both R&D laboratories and large-scale production facilities. The dual-layer servo-driven feeder ensures ±1-2% weight variation, critical for maintaining dosage uniformity per USP <905> and EP 2.9.40 standards.

Constructed with 316L stainless steel punch tips and hardened steel die tables with Ra ≤ 0.4 μm surface finish, our machines meet cGMP, CE, and FDA 21 CFR Part 11 requirements. The 10-inch touch-screen HMI allows operators to switch between tablet sizes (6-25mm diameter) in under 30 minutes, with pre-set compression recipes stored for instant recall.

  • 15+ years of tablet press manufacturing expertise
  • Installed in 30+ countries worldwide
  • IQ/OQ/PQ validation documentation included
  • Custom punch tooling and die configurations available

How It Works

5-step rotary compression cycle for precise tablet formation

1

Powder Feeding

Die table rotates under the feed frame where dual-layer servo-driven feeders distribute granules evenly into each die cavity. Adjustable feed blade speed ensures uniform fill depth for consistent tablet weight.

2

Pre-Compression

Upper and lower punches enter the die cavity to apply pre-compression force (adjustable 10-50 kN), expelling air from the powder bed and forming a preliminary compact. This prevents lamination and capping defects.

3

Main Compression

The main compression rolls apply final tableting force (up to 150 kN), compressing the tablet to target hardness. Closed-loop servo force control maintains ±1% accuracy across all stations simultaneously.

4

Tablet Ejection

Lower punches rise to eject tablets from the die cavity onto the take-off blade. An anti-sticking film on the punch faces prevents adherence. Scrapers keep punch heads clean for consistent compression.

5

Quality Control & Discharge

Optional in-line metal detectors and weight checkers inspect 100% of tablets. Under/over-weight tablets and those with metallic foreign matter are automatically rejected. Output rates up to 400,000 tablets/hour.
