6-Ton Small Single-Punch Tablet Press — Laboratory Powder & Granule Tableting Equipment / Tablet Forming Machine

Product Overview

This 6-ton single punch tablet press is a precision-engineered solution for compacting granular and powdered materials into uniform tablets. Designed to meet the rigorous demands of laboratory research, pilot-scale production, and small-batch manufacturing, the unit combines mechanical simplicity with outstanding adjustability. The integrated feeding, pressing, and ejection sequence is driven by a robust main shaft and dual cam mechanism, delivering reliable cycle times and consistent tablet quality. The machine's compact footprint and rugged cast-iron construction make it an ideal choice for environments where space is limited but performance cannot be compromised.

The press caters to a broad spectrum of industries, including pharmaceuticals, chemicals, food processing, ceramics, and academic research. It is ideally suited for producing tablets from free-flowing powders, whether for drug formulation trials, catalyst development, or dietary supplement prototyping. Its ability to handle a wide range of materials—from delicate herbal extracts to abrasive chemical compounds—makes it a versatile tool in any laboratory setting. The operating cycle consists of three coordinated phases: the suction shoe fills the die cavity, the upper punch descends to compress the powder, and the lower punch ejects the finished tablet. Both cam profiles are precisely machined to ensure smooth acceleration and deceleration, reducing stress on components and enhancing tablet uniformity.

Built on a single-piece cast-iron frame, the machine offers exceptional stability and vibration damping during operation. The precisely machined gears and cams ensure accurate alignment and long service life, even under frequent use. With straightforward maintenance and the option for manual hand-crank operation, this tablet press is engineered to deliver dependable performance in environments where uptime and precision are critical. The hand-crank capability proves invaluable during power outages or when producing extremely small batches where motor-driven speed may be too fast for delicate formulations.

Key Features

• Wide Material Adaptability: Whether working with abrasive ceramics, sticky herbal blends, or free-flowing chemical powders, the open feed shoe and short fill distance minimize segregation and bridging. Standard tooling coated with industrial hard chrome extends die life and reduces cleaning frequency, enabling rapid changeover between formulations without cross-contamination.
• Independent Filling and Thickness Control: Fill depth (up to 17 mm) and tablet thickness are independently adjustable via graduated knobs, giving operators precise command over tablet weight and density without tools. This dual adjustment capability is essential for achieving target dissolution profiles and mechanical strength in pharmaceutical tablets.
• Adjustable Compression Force: The maximum pressing force of 60 kN (6 tons) is achieved via a geared disk adjustment mechanism, allowing fine-tuning of the compression to suit material characteristics and desired tablet hardness. The pressure remains consistent once set, eliminating variability from operator technique.
• High-Speed Continuous Operation: With a main shaft speed of 1400 r/min, the press produces up to 3000 tablets per hour. An optional frequency converter enables variable speed control, slowing the cycle for brittle materials or maximizing throughput for robust formulations.
• Versatile Die Compatibility: Accepts punch dies from 4 mm to 25 mm in diameter, accommodating round, oval, or irregular shapes by simply swapping die sets. This adaptability supports rapid product development, allowing a single machine to serve multiple projects with minimal investment in tooling.
• Manual Hand Crank Mode: In the absence of electricity or for low-volume experimental runs, the hand crank drive provides a practical alternative. The flywheel design maintains momentum between strokes, reducing operator fatigue and ensuring consistent tablet density.
• Robust Cast-Iron Construction: The one-piece body eliminates structural flexing, maintaining die alignment and reducing maintenance. The durable finish resists corrosion from common pharmaceutical ingredients such as citric acid, sodium bicarbonate, and herbal tinctures.
• Simple Maintenance Design: Accessible internal components and a straightforward mechanical layout minimize downtime. Routine cleaning and lubrication can be performed quickly without specialized tools, keeping the press in optimal condition even in multi-shift operations.
• Low Noise and Vibration: The integrated gear train and balanced flywheel contribute to quiet operation, typically below 65 dB, making the unit suitable for laboratory environments where noise reduction is valued.

Why Choose This Product

• Proven Long-Term Reliability: The heavy-duty cast-iron chassis and precision-ground gears are designed to withstand years of daily use without performance degradation. Bearings are oversized for the load, and all wear surfaces are hardened, offering a low total cost of ownership and minimal unplanned downtime.
• Precision Manufacturing: Tight tolerances in the die set and guide rails, combined with the micro-adjustable fill and pressure controls, enable repeatable tablet weight within narrow margins—critical for quality-controlled environments. Each press undergoes factory calibration and test runs before shipping.
• Unmatched Flexibility: From 4 mm micro-tablets to 25 mm large lozenges, and from motorized high-throughput runs of 3000 tablets per hour to delicate manual single-punch operations, this machine adapts to your workflow. The same unit can serve R&D in the morning and small-scale production in the afternoon.
• Comprehensive Support: Our team provides full lifecycle support, including rapid spare parts delivery, expert technical consultation, and optional extended warranties. We assist with die selection, formulation advice, and on-site training to ensure you extract maximum value from the investment.
• Space-Efficient Design: With overall dimensions of just 760 × 360 × 690 mm, the press fits easily into crowded laboratories or pilot plants. The integrated hand-crank capability eliminates the need for a dedicated power source in temporary setups, simplifying installation.
