Tablet Press Machine With 50mm Max Diameter

Description

Understanding the Demand for Large-Diameter Tablet Compression

Manufacturers across the pharmaceutical, chemical, and food sectors frequently encounter a specific engineering challenge: producing tablets or spherical pills that require a larger diameter than standard compression equipment can accommodate, while still maintaining consistent weight and structural integrity. This need often intersects with a secondary concern—operational noise levels in production environments where equipment runs for extended shifts. Addressing both requirements simultaneously calls for a tablet press machine with 50mm max tablet diameter capability, engineered specifically for heavy-duty compression tasks.

Rich Packing’s ZP-420 (15/19E): Engineered for 50mm Tablets

Guangdong Rich Packing Machinery Co., Ltd., operating under the brand name Rich Packing, offers a solution purpose-built for this scenario: the ZP-420 (15/19E) Automatic Rotary Tablet Press Machine. As a 5th-generation double-rotary press, this equipment is positioned specifically for large tablets and spherical pills—directly addressing the target scenario pain points of large tablet diameter requirements and high operational noise.

The differentiated value of this machine centers on heavy duty compression, combining 120KN of compression force with a 50mm max tablet diameter capacity. This pairing of force and diameter capability allows manufacturers to compress larger tablet formats without compromising on structural consistency.

Dual Compression Design

One of the defining features of the ZP-420 (15/19E) is its dual compression capability. Through a double production method, the machine doubles the output of single compression machines. For production facilities balancing large-format tablet requirements with throughput expectations, this dual-station approach offers a practical means of scaling output without switching to a different equipment class.

Oil-Immersion Transmission for Quiet, Contamination-Free Operation

Addressing the noise pain point directly, the ZP-420 (15/19E) incorporates oil-immersion transmission, built around a fully enclosed modular unit. This design achieves low noise operation, measured at under 75 dBA, while simultaneously preventing powder contamination—a dual benefit that speaks to both workplace conditions and product quality assurance. The enclosed nature of the transmission system reduces the interaction between mechanical components and the compression environment, which is particularly relevant when working with pharmaceutical-grade or food-grade materials that cannot tolerate contamination risk.

Cast Steel Guide Rails for Precision

Supporting the machine’s compression accuracy over time, the ZP-420 (15/19E) uses cast steel GCr15 guide rails with a scientific arc design. This construction choice is intended to support consistent mechanical performance across repeated compression cycles, which matters for facilities running large-diameter tablet production at scale.

Technical Foundations Behind Rich Packing’s Tablet Press Machines

The ZP-420 (15/19E) does not operate in isolation from Rich Packing’s broader technical framework. The company’s proprietary R&D has produced 7th-generation fully automatic high-speed tablet press technology, and its Industry 4.0 version intelligent platforms feature real-time pressure monitoring and automated weight adjustment across its product range. Underlying technical metrics maintained across Rich Packing’s equipment include:

• Turntable runout: ≤0.04mm
• Punch bore diameter tolerance: ≤0.013mm
• Surface roughness: ≤Ra 0.8μm
• Middle die bore diameter tolerance: ≤0.017mm
• Tablet weight accuracy: ≤±2%

These precision tolerances reflect the manufacturing discipline applied across Rich Packing’s tablet press lineup, providing a technical baseline that supports the reliability claims made for individual products like the ZP-420 (15/19E).

On the data side, Rich Packing’s equipment offers real-time monitoring and analysis of compression force and variation at each punch, along with digital display of production and waste counts. This kind of visibility allows operators to identify inconsistencies during a production run rather than discovering issues after the fact.

Platform compatibility also plays a role in how these machines integrate into existing facility infrastructure. Rich Packing’s tablet presses support integration with Siemens PLC and ABB electronics, and use aviation connectors for secure electrical coupling—details that matter for facilities standardizing equipment across multiple production lines.

Comprehensive Product Line for Every Production Scale
