Jing Tuo PP-20S 20-Ton Fully Automatic Powder Pellet Press

Overview

The Jing Tuo PP-20S is a fully automatic hydraulic-servo hybrid powder pellet press engineered for high-precision, repeatable sample preparation in analytical and materials laboratories. It operates on the principle of uniaxial cold compaction under controlled force, displacement, and dwell time—enabling reproducible formation of homogeneous, binder-free pellets suitable for X-ray fluorescence (XRF), Fourier-transform infrared (FTIR), near-infrared (NIR), and elemental analysis by wavelength-dispersive spectroscopy (WDS). Designed for routine QC/QA workflows and research-grade sample standardization, the PP-20S integrates closed-loop pressure feedback, real-time stroke monitoring, and programmable compression profiles to ensure metrological traceability across batches. Its robust architecture complies with mechanical safety standards for laboratory press equipment (EN 692, ISO 13857), and all force calibration procedures align with ISO/IEC 17025 requirements for testing laboratories.

Key Features

• Fully automated operation with pre-programmable multi-step compression cycles—including pre-compaction, main compression, dwell, and controlled ejection—executed via an industrial-grade PLC and 7-inch capacitive touchscreen HMI.
• Hydraulic-servo dual-drive system delivering stable 20-ton (196 kN) maximum compressive force with <±0.5% pressure repeatability under identical parameter sets.
• Integrated force and displacement sensors calibrated to NIST-traceable standards; real-time data logging at 100 Hz sampling rate during compression.
• Modular die set compatibility: accepts standard 13 mm, 25 mm, and 30 mm diameter stainless-steel die assemblies (ASTM E11-22 compliant); optional custom cavity geometries available upon request.
• Auto-calibration function for zero-point drift compensation and pressure sensor linearity verification prior to each operational session.
• Emergency stop circuitry, dual-hand safety interlock, and physical guard barriers conforming to IEC 60204-1 for industrial control equipment safety.

Sample Compatibility & Compliance

The PP-20S accommodates a broad spectrum of inorganic and organic powdered samples—including metal oxides, geological matrices (e.g., fused beads, soil digests), pharmaceutical excipients, polymer blends, and ceramic precursors—without requiring binders or lubricants in most applications. It supports both loose-powder loading and pre-weighed capsule-based feeding protocols. All wetted components are constructed from 316L stainless steel or hardened tool steel, ensuring chemical inertness against common acids, bases, and halogenated solvents encountered during sample digestion workflows. The system meets GLP documentation requirements through audit-ready event logging (including operator ID, timestamp, force curve, and cycle parameters), and its firmware architecture supports 21 CFR Part 11-compliant electronic signatures when paired with validated LIMS integration.

Software & Data Management

The embedded control software provides native CSV export of full compression curves (force vs. displacement), cycle summary reports, and calibration history. Optional PC-based software (Jing Tuo PelletSuite™ v3.2) enables advanced protocol management, statistical process control (SPC) charting, and comparative analysis across multiple instruments. All data files include embedded metadata tags (ISO 8601 timestamps, instrument serial number, user credentials, and environmental ambient readings if external sensors are connected). Audit trails record every parameter modification, login attempt, and calibration action with immutable timestamps—fully compatible with ISO/IEC 17025 Clause 7.7 and FDA data integrity expectations.

Applications

• Preparation of pressed pellets for quantitative XRF analysis of cement, ores, slag, and fly ash per ASTM C114 and ISO 29581-2.
• Standardized tablet fabrication for FTIR transmission and ATR quantification of active pharmaceutical ingredients (APIs) under USP <851> guidelines.
• Production of uniform density reference discs for laser-induced breakdown spectroscopy (LIBS) calibration and matrix-matched validation.
• Routine quality control of catalyst powders, battery electrode materials, and refractory ceramics where green density and compact homogeneity directly impact downstream sintering behavior.
• Research-scale densification studies requiring precise correlation between applied stress, relative density, and microstructural evolution (e.g., Heckel analysis, Kawakita modeling).

FAQ

What is the maximum recommended die diameter for routine use on the PP-20S?

The standard configuration supports up to 30 mm diameter dies; larger cavities may be used with force derating per ISO 14644-1 guidance to maintain structural integrity and measurement fidelity.
Does the PP-20S support GMP-compliant operation out of the box?

Yes—the system includes built-in electronic signature capability, role-based access control, and configurable audit trail retention (minimum 18 months), meeting baseline GMP Annex 11 expectations when deployed with validated IT infrastructure.
Can the compression profile be exported and shared across multiple PP-20S units?

Yes—protocol files (.jtp) are platform-independent and can be loaded via USB or network transfer; version-controlled protocol libraries are supported in PelletSuite™.
Is third-party calibration certification available?

Jing Tuo partners with CNAS-accredited metrology labs in China and EU-based DAkkS-certified providers for annual force calibration with full uncertainty budget reporting (k=2).
How is maintenance documented and tracked?

Each unit includes a digital maintenance logbook synchronized with the HMI; service events trigger automatic PDF report generation with technician signature, parts list, and post-service verification results.
