YANRUN AXQ-50 Intelligent Fully Automatic Hot Mounting Press

Overview

The YANRUN AXQ-50 Intelligent Fully Automatic Hot Mounting Press is an integrated, floor-standing thermal compression system engineered for high-throughput, repeatable, and dimensionally stable metallographic specimen preparation. It operates on the principle of thermosetting resin consolidation under controlled temperature and uniaxial pressure—enabling rapid encapsulation of irregular, fragile, or sub-millimeter specimens within rigid polymer matrices (e.g., phenolic, epoxy, or acrylic resins). This process eliminates edge rounding, preserves microstructural integrity at phase boundaries, and ensures uniform thermal expansion behavior during subsequent grinding and polishing. Unlike manual or semi-automatic presses, the AXQ-50 executes the full mounting cycle—including heating, pressurization, dwell, and active water-cooled solidification—without operator intervention. Its design complies with fundamental requirements outlined in ASTM E3-22 (Standard Guide for Preparation of Metallographic Specimens) and ISO 13071-1:2021 (Metallographic specimen mounting—Part 1: Thermosetting resins), supporting laboratories operating under GLP or ISO/IEC 17025-accredited quality frameworks.

Key Features

• PLC-based intelligent control architecture with a 7-inch color touchscreen HMI, offering menu-driven programming for temperature ramp rate, dwell duration, pressure profile, and cooling sequence—each parameter independently adjustable and storable as user-defined protocols.
• Pneumatic actuation system delivering precise, oil-free compression force across the full 0–2 MPa range; calibrated air supply (0.5–0.8 MPa) ensures consistent load application without hydraulic fluid maintenance or leakage risk.
• Dual-mode thermal management: 1000 W resistive heating elements enable rapid ramp-up to 300 °C, while a closed-loop circulating water chiller reduces specimen temperature from molding point to handling threshold in under 90 seconds—critical for minimizing thermal degradation of heat-sensitive phases or coatings.
• Modular die system with quick-release steel mold sleeves (Φ25 mm, Φ30 mm, Φ40 mm, Φ45 mm), allowing seamless transition between standard specimen geometries without tooling recalibration or downtime.
• Fully automated vertical ram motion with position-sensing feedback ensures repeatable platen closure and uniform pressure distribution across the entire mounting interface—eliminating tilt-induced density gradients common in mechanical screw-type systems.

Sample Compatibility & Compliance

The AXQ-50 accommodates all thermosetting embedding media approved for metallography, including but not limited to phenol-formaldehyde, melamine-formaldehyde, and high-strength epoxy formulations. It is unsuitable for thermoplastic resins (e.g., acrylics requiring cold-mounting) due to its dedicated hot-compression architecture. Specimen types include sintered powders, thin foils, wire cross-sections, coated substrates, and brittle ceramics—provided dimensional stability is maintained during pre-mounting handling. The system meets mechanical safety requirements per IEC 61000-6-2 (EMC immunity) and thermal enclosure standards per IEC 60529 (IP20 ingress protection). Documentation supports traceability for internal audit and external accreditation (e.g., ISO/IEC 17025 clause 6.4.10 on equipment verification).

Software & Data Management

While the AXQ-50 does not feature networked software or remote PC interface, its embedded PLC firmware logs all critical cycle parameters—including actual vs. setpoint temperature curves, applied pressure over time, and cooling rate profiles—in non-volatile memory. Cycle reports can be exported via USB flash drive in CSV format for integration into LIMS or QA documentation workflows. All parameter changes are timestamped and attributed to operator ID (via optional login module), satisfying basic audit-trail requirements aligned with FDA 21 CFR Part 11 Annex A (electronic records integrity) when used in regulated environments.

Applications

• Routine quality control labs performing incoming material verification (e.g., ASTM E112 grain size analysis, ASTM E1245 inclusion rating).
• Failure analysis centers preparing fracture surfaces or corrosion cross-sections where edge retention is paramount.
• Research institutions conducting multi-phase alloy characterization, additive manufacturing microstructure evaluation, or interfacial adhesion studies.
• Electronics packaging labs embedding solder joints, wire bonds, or PCB cross-sections for void and intermetallic layer assessment.
• Coating & surface engineering labs evaluating thermal spray, PVD/CVD layers, or diffusion barrier integrity under metallurgical sectioning.

FAQ

What types of mounting resins are compatible with the AXQ-50?
The AXQ-50 is designed exclusively for thermosetting resins (e.g., phenolic, epoxy, diallyl phthalate) that cure under heat and pressure. Thermoplastic resins (e.g., acrylics) require cold-mounting equipment and are not supported.
Is the water cooling system self-contained?
Yes—the unit includes an integrated recirculating chiller with reservoir, pump, and heat exchanger. Connection to facility water is not required, though optional external heat rejection may be configured for high-duty-cycle operation.
Can the AXQ-50 be validated for GMP compliance?
While the base configuration lacks built-in IQ/OQ documentation templates, its deterministic control logic, parameter logging, and mechanical reproducibility support qualification under ASTM E2500-13 (Verification and Validation of Pharmaceutical Manufacturing Equipment) when paired with third-party protocol development and calibration certification.
What maintenance is required for long-term reliability?
Routine tasks include monthly inspection of pneumatic fittings, quarterly descaling of the water circuit using citric acid solution, and annual verification of thermocouple accuracy against NIST-traceable reference standards.
Does the system support custom mold geometries beyond the four standard diameters?
Yes—custom steel mold sleeves (e.g., rectangular, dual-cavity, or stepped-diameter) can be manufactured to OEM specifications and retrofitted using the same quick-change interface.
