Description

Manufacturers across the pharmaceutical, chemical, and food sectors continue to search for compression equipment that can eliminate powder segregation, control tablet weight variance, and sustain high-volume output without sacrificing precision. Guangdong Rich Packing Machinery Co., Ltd., operating under the brand Rich Packing, has built its product portfolio around these exact concerns, positioning itself as a high-tech intelligent manufacturing solution provider specializing in Industry 4.0 compliant pharmaceutical machinery. Among its seven-product tablet press lineup, the models equipped with a high-speed rotary press with pre-pressing system stand out as direct answers to common production pain points.

Addressing Industry Pain Points in Tablet Compression

The core industry insight driving Rich Packing’s engineering approach is the need for stable tablet weight, reduced material waste, prevention of powder segregation, and reliable performance under high-volume production demands. These challenges are particularly acute when air becomes trapped inside powder during compression, or when material exhibits poor plasticity — issues that a pre-pressing system is specifically designed to resolve.

Engineering Excellence Behind the Pre-Pressing System

RQ-HGZP (45D-75D) Fully Auto High Speed Tablet Press Machine

Positioned as a 6th-generation high-speed press for mass production, the RQ-HGZP (45D-75D) targets scenario pain points including air trapped in powder and poor material plasticity. Its differentiated value centers on volume output, combining high-speed operation with a maximum output of 680,000 tablets/hour. The defining feature is its Pre-pressing System, which applies 20KN pre-compression force to deaerate powder before final compression, directly improving tablet quality. This is paired with an Intelligent Lubrication feature using progressive sealed delivery for independent supply of oil and grease. A further technical highlight is the use of pressure sensors that monitor every punch set’s pressure in real-time.

RQ-HGZP (51D-83D) Fully Auto High Speed Tablet Press Machine

For operations requiring even greater throughput, the RQ-HGZP (51D-83D) is classified as a 7th-generation ultra-high-speed intelligent press. It is engineered to solve underfeeding at high speeds and material spillage, two issues that intensify as compression speed increases. Its differentiated value, described as peak performance, reflects its Industrial 4.0 version platform and a maximum output of 720,000 tablets/hour. The pre-pressing capability here is substantial: 100KN pre-pressing pressure combined with 100KN main pressure. Supporting features include a Triple Impeller Feeder — a three-impeller system ensuring uniform feeding for high stability — and Frequency-Coupled Speed, which synchronizes the feeder and main motor to prevent underfeeding.

Together, these two models demonstrate how Rich Packing applies pre-pressing technology across different generations and output tiers, allowing manufacturers to select equipment that matches their specific production scale while still benefiting from deaeration-focused compression control.

Precision Manufacturing Standards

Rich Packing’s broader technical capability system underpins the performance of its pre-pressing equipped presses. The company’s proprietary R&D has produced 7th-generation fully automatic high-speed tablet press technology, built on Industry 4.0 version intelligent platforms that feature real-time pressure monitoring and automated weight adjustment. Documented technical metrics across the product line 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 tolerances matter directly to users of the pre-pressing models, since consistent bore diameters and low turntable runout support the pressure sensors’ ability to accurately track punch-by-punch performance during pre-compression and main compression stages.

Data-Driven Intelligent Monitoring

A key data capability shared across the tablet press line is real-time monitoring and analysis of compression force/variation of each punch, alongside digital display of production and waste counts. For high-speed rotary presses running pre-pressing cycles, this monitoring capability allows operators to observe how the 20KN or 100KN pre-compression forces interact with the main pressure stage, and to make informed adjustments when variation is detected.

Platform Compatibility

Rich Packing’s presses integrate with Siemens PLC and ABB electronics, using aviation connectors for secure electrical coupling. This platform compatibility supports the automated responsiveness required by pre-pressing systems, particularly the PLC auto-response mechanism referenced in the company’s hydraulic stabilization feature found on related models in the lineup, which ensures stable hydraulic pressure and low noise.

Service and Delivery Capabilities

Beyond hardware, Rich Packing provides on-site commissioning and after-sales services, along with a tool-free changeover of molds within 30 minutes, reducing downtime between production runs. The delivery model is structured around on-premises hardware installation, with after-sales support covering both commissioning and maintenance — an important consideration for manufacturers integrating a high-speed rotary press with a pre-pressing system into continuous production lines.

Industry Applications and Market Reach

The pre-pressing equipped models, along with the rest of the seven-product tablet press portfolio, serve the pharmaceutical, chemical, electronics, and food industries. Customer types include large enterprises, mass production facilities, and pharmaceutical manufacturers, all of which require equipment capable of handling high-volume runs without compromising tablet consistency. The pre-pressing feature, in particular, addresses a technical requirement common across these sectors: removing trapped air from powder formulations before the final compression stroke, which reduces the likelihood of capping, lamination, or weight inconsistency in the finished tablet.

Conclusion

For manufacturers evaluating a high-speed rotary press with pre-pressing system, Rich Packing’s RQ-HGZP (45D-75D) and RQ-HGZP (51D-83D) models illustrate how deaeration-focused pre-compression, ranging from 20KN to 100KN depending on the generation and output tier, is engineered into machines capable of 680,000 to 720,000 tablets/hour. Combined with documented precision tolerances, real-time punch-level monitoring, Siemens PLC and ABB electronics integration, and structured after-sales support, these systems reflect Rich Packing’s stated positioning as a provider focused on stable tablet weight, reduced material waste, and compliance with high-volume production needs across pharmaceutical, chemical, and food manufacturing environments.
