HengaoDe H17909 Manual Powder Press (15-Ton Hydraulic Tablet Press)

Overview

The HengaoDe H17909 Manual Powder Press is a compact, manually operated hydraulic press engineered for reproducible sample compaction in laboratory-scale powder characterization, pharmaceutical tablet development, and materials research. It operates on the principle of static hydraulic force transmission via a hand-pumped oil circuit, delivering controlled uniaxial pressure to powdered specimens confined within standardized die sets. Unlike motorized or pneumatic systems, the H17909 relies on mechanical advantage and sealed hydraulic integrity to achieve stable dwell pressure—critical for producing uniform pellets for X-ray fluorescence (XRF), Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and elemental analysis. Its design prioritizes operational simplicity, minimal maintenance, and compliance with foundational lab safety and calibration traceability expectations.

Key Features

• Stable 15-ton (147 kN) maximum compressive force, calibrated to ±2% full scale per ISO 7500-1 guidelines for static force measurement.
• Forged steel frame with precision-machined piston bore (70 mm diameter) and hardened chrome-plated ram for long-term dimensional stability and corrosion resistance.
• Integrated pressure-hold mechanism prevents load decay during dwell—verified by ≤0.5% pressure loss over 60 seconds at 12 t.
• Low-profile platform (100 mm × 100 mm) accommodates standard stainless-steel dies (e.g., 13 mm, 25 mm, 32 mm diameter) and custom tooling up to 115 mm total height.
• Ergonomic two-stage hand lever with tactile feedback; average effort required to reach 10 t is <22 kgf, minimizing operator fatigue during repeated use.
• Non-electric operation ensures intrinsic safety in solvent-rich or explosion-hazard environments (no spark risk, no grounding requirement).

Sample Compatibility & Compliance

The H17909 supports dry, granular, or lightly agglomerated powders—including metal oxides, ceramic precursors, pharmaceutical actives (APIs), catalysts, and geological standards—with particle sizes ranging from submicron to 500 µm. It is routinely employed in preparation of pressed pellets meeting ASTM E1361 (XRF), ISO 12847 (XRD), and USP <1057> (pharmaceutical solid dosage form development) requirements. While not certified to GLP or GMP as a standalone instrument, its mechanical repeatability and documented force-output linearity support audit-ready documentation when paired with external calibration certificates (e.g., NIST-traceable load cell verification). The unit complies with CE machinery directive 2006/42/EC for manually actuated equipment and carries IP20 ingress protection rating for indoor laboratory use.

Software & Data Management

As a purely mechanical device, the H17909 does not incorporate embedded electronics, firmware, or digital interfaces. All operational parameters—including applied force, dwell time, and die geometry—are recorded manually in lab notebooks or electronic lab notebooks (ELNs) such as LabArchives or Benchling. For traceability, users are advised to log: date/time, operator ID, batch number, powder mass, die ID, target pressure, actual pump strokes, dwell duration, and post-press pellet dimensions (measured via caliper or micrometer). Optional external digital pressure transducers (e.g., WIKA A10 series, 0–200 bar, 4–20 mA output) may be integrated into the hydraulic line for real-time force monitoring and data logging via USB DAQ systems compliant with FDA 21 CFR Part 11 when used in regulated environments.

Applications

• Preparation of homogeneous XRF calibration standards and unknowns from certified reference materials (CRMs).
• Compaction of battery electrode slurries (e.g., LiCoO₂, graphite) into free-standing electrodes for electrochemical impedance spectroscopy (EIS) and conductivity testing.
• Forming ceramic green bodies for sintering trials and density correlation studies (ASTM C20).
• Producing IR-transparent KBr pellets for qualitative and quantitative organic compound identification.
• Generating consolidated soil or sediment cores for permeability and compressibility index determination (ASTM D2435).
• Creating metallurgical mounts for hardness testing (ASTM E10, E18) where hot-pressing is impractical.

FAQ

What is the recommended maintenance schedule for the H17909?
Perform hydraulic oil level check before each use; replace ISO VG 32 mineral hydraulic oil annually or after 500 operating cycles. Clean piston rod and cylinder bore with lint-free cloth and light machine oil after exposure to corrosive or hygroscopic powders.
Can the H17909 be used with heated dies?
No. The unit is rated for ambient temperature operation only (15–30°C). External heating of dies is not supported and may compromise seal integrity or cause thermal expansion misalignment.
Is calibration certification included with purchase?
A factory-issued mechanical calibration report (force vs. pump stroke curve) is provided. NIST-traceable third-party calibration is available upon request at additional cost.
What die sizes are compatible with the 115 mm height clearance?
Standard configurations include 13 mm, 25 mm, and 32 mm diameter dies with heights ≤115 mm. Custom dies must maintain concentricity tolerance ≤0.05 mm and surface finish Ra ≤0.8 µm for optimal pellet ejection.
Does the press meet ISO 9001 requirements for production environments?
While the H17909 itself is not ISO 9001-certified, its consistent mechanical performance enables integration into ISO 9001-compliant QA workflows when used with documented SOPs, preventive maintenance logs, and operator training records.
