JIA XIN HAI JYP-24-D Manual Hydraulic Pellet Press

Overview

The JIA XIN HAI JYP-24-D Manual Hydraulic Pellet Press is a precision-engineered laboratory instrument designed for reproducible sample compaction into uniform, dimensionally stable pellets—primarily for spectroscopic analysis (e.g., FTIR, XRF, XRD) and elemental quantification workflows. It operates on a dual-stage hydraulic principle: initial coarse positioning via manual eccentric shaft adjustment, followed by fine pressure application through a manually actuated hydraulic system with integrated pressure amplification. The press delivers controlled, repeatable force transmission to the die cavity without electrical or pneumatic dependencies—ensuring operational reliability in environments with limited infrastructure or stringent electromagnetic compatibility requirements. Its robust cast-iron frame, hardened steel columns, and precision-machined oil cylinder assembly provide long-term mechanical stability and minimal elastic deformation under load, critical for maintaining pellet density consistency across batches.

Key Features

• Manual hydraulic operation with dual-stage pressure control: coarse pre-compression via eccentric shaft + fine-tuned hydraulic loading up to 24 tons (240 kN) nominal capacity
• Integrated analog pressure gauge (0–60 MPa range) with calibrated scale and stainless-steel connecting column for real-time force monitoring
• Dual-spring hydraulic system: high-pressure spring (upper chamber) and low-pressure spring (lower chamber) ensure smooth piston return and consistent stroke recovery
• Sealed hydraulic circuit with double-row sealing balls on plunger rod and plunger sleeve, minimizing fluid leakage and extending service life
• Modular die interface compatible with standard 13 mm, 25 mm, and 32 mm diameter molds; includes mold matching table for precise alignment verification
• Machined aluminum oil reservoir with transparent level indicator and threaded fill port (M12×1.5) for ISO VG 32 hydraulic oil
• Full mechanical lock mechanism with locking nut and release valve rod for safe pressure retention and controlled depressurization

Sample Compatibility & Compliance

The JYP-24-D accommodates dry, granular, or powdered samples—including inorganic oxides, metal alloys, geological powders, pharmaceutical excipients, and polymer blends—provided they exhibit sufficient flowability and compressibility. It supports preparation of pellets meeting ASTM E1318 (XRF sample preparation), ISO 12847 (FTIR KBr disc methodology), and USP <731> (pharmaceutical tablet hardness testing protocols) when used with certified dies and standardized procedures. While not intrinsically GLP/GMP-certified, its mechanical traceability—via pressure gauge readings, manual stroke count, and physical lock engagement—enables audit-ready documentation when integrated into validated lab SOPs. No electronic components or firmware are present, eliminating concerns related to FDA 21 CFR Part 11 compliance for purely manual data recording.

Software & Data Management

This is a fully manual, non-digital instrument with no embedded electronics, microprocessors, or connectivity interfaces. All operational parameters—including applied pressure (read from analog gauge), compression duration (timed externally), and die configuration—are recorded manually in laboratory notebooks or LIMS-compatible spreadsheets. Users may pair the press with external digital force sensors or USB-connected pressure transducers (e.g., Omega PX409 series) for enhanced data logging, though such integration requires third-party calibration and validation per ISO/IEC 17025 requirements. No proprietary software, drivers, or cloud services are provided or supported.

Applications

• Preparation of homogeneous pellets for Fourier-transform infrared (FTIR) spectroscopy using KBr or polyethylene matrices
• Compaction of mineralogical powders for wavelength-dispersive X-ray fluorescence (WDXRF) quantitative analysis
• Formation of pressed discs for X-ray diffraction (XRD) phase identification with minimized preferred orientation effects
• Production of reference standards and calibration tablets in analytical chemistry and quality control laboratories
• Material science research involving cold isostatic pressing (CIP) simulation for ceramic green body fabrication
• Environmental testing labs preparing soil/sediment pellets for heavy metal screening via portable XRF analyzers

FAQ

What is the maximum rated pressure output of the JYP-24-D?
The press is engineered for a nominal maximum hydraulic pressure of 60 MPa, corresponding to approximately 24 tons (240 kN) of compressive force at the platen interface when used with a standard 25 mm die.
Does the unit include dies or is mold selection optional?
No dies are included by default. A comprehensive mold matching table is supplied to guide selection of commercially available stainless-steel or hardened tool-steel dies (13 mm, 25 mm, 32 mm inner diameters) compatible with the platen geometry and pressure distribution profile.
How often does the hydraulic oil require replacement?
Under normal laboratory use (≤50 cycles/week), ISO VG 32 hydraulic oil should be replaced every 12 months or after 500 compression cycles—whichever occurs first—to maintain viscosity stability and prevent seal degradation.
Can the JYP-24-D be adapted for vacuum-assisted pressing?
No. The press lacks vacuum ports, sealing gaskets, or chamber integration capability. Vacuum de-airing must be performed separately prior to loading into the die cavity.
Is technical support available outside China?
Yes. JIA XIN HAI provides English-language documentation, dimensional drawings, and remote troubleshooting via email and video call. Spare parts—including O-rings, sealing balls, and pressure gauge assemblies—are stocked internationally through authorized distributors in North America and the EU.
