YANRUN AXQ-5 Intelligent Automatic Hot Mounting Press

Overview

The YANRUN AXQ-5 Intelligent Automatic Hot Mounting Press is a benchtop, fully automated thermosetting sample mounting system engineered for precision, repeatability, and high-throughput metallographic specimen preparation. It operates on the principle of hot compression molding—applying controlled heat and pneumatic pressure to consolidate thermosetting resins (e.g., phenolic, epoxy, or acrylic) around metallic, ceramic, or composite specimens, forming dimensionally stable, edge-retentive mounts suitable for subsequent grinding, polishing, and microscopic analysis. Unlike cold-mounting systems, the AXQ-5 delivers superior interfacial adhesion, minimal void formation, and enhanced edge protection—critical for analyzing fine microstructures, coating interfaces, porosity, and inclusion distribution in ASTM E3, ISO 14489, and GB/T 13298-compliant workflows. Its integrated water-cooling module enables rapid thermal quenching post-cure, reducing cycle time without compromising resin crosslinking integrity.

Key Features

• Intelligent PLC-based control architecture with Mitsubishi FX-series logic controller and a 7-inch color touchscreen HMI—supporting multi-step programmable profiles for temperature ramping, dwell time, pressure application, and cooling sequencing.
• Pneumatic actuation system (0.5–0.8 MPa supply pressure) ensures consistent, oil-free, and maintenance-light compression force delivery; eliminates hydraulic fluid contamination risks common in legacy mechanical presses.
• Modular interchangeable steel mold sleeve design supports four standard mounting diameters: 25 mm, 30 mm, 40 mm, and 45 mm—enabling seamless adaptation across diverse specimen geometries without hardware reconfiguration.
• Automated vertical sample elevation via pneumatically driven platen ensures precise alignment and uniform pressure distribution during curing—minimizing tilt-induced resin migration or specimen displacement.
• Dual-mode thermal management: 1000 W resistive heating element with ±1.5 °C PID-controlled stability across 0–300 °C range; coupled with intelligent timed water-cooling for programmable post-cure thermal arrest.
• Self-diagnostic startup sequence, real-time parameter logging, and emergency stop with mechanical pressure release meet IEC 61000-6-2 EMC and ISO 13857 safety requirements for laboratory equipment.

Sample Compatibility & Compliance

The AXQ-5 accommodates all thermosetting embedding media—including phenolic (high hardness, low shrinkage), epoxy (excellent edge retention, low exotherm), and diallyl phthalate (DAP, for high-temperature applications)—but is not compatible with thermoplastic resins (e.g., acrylics requiring solvent-based cold mounting). It supports specimens ranging from sub-millimeter particles to irregularly shaped components ≤45 mm in maximum dimension. The system conforms to core metallographic preparation standards including ASTM E3-22 (Standard Guide for Preparation of Metallographic Specimens), ISO 14489:2022 (Metallographic specimen mounting), and GB/T 13298-2015 (Metallographic specimen preparation for microstructure examination). All operational parameters—including temperature setpoint, dwell duration, applied pressure, and cooling delay—are logged with timestamped records, supporting GLP/GMP-aligned audit trails when integrated with compliant LIMS environments.

Software & Data Management

While the AXQ-5 operates as a standalone instrument with embedded firmware, its touchscreen interface stores up to 99 user-defined mounting protocols—including ramp rates, hold times, peak temperatures, and pressure curves—with password-protected access levels for operator, supervisor, and administrator roles. Parameter logs (date/time, cycle ID, operator ID, actual vs. target T/P values) are exportable via USB flash drive in CSV format for traceability. Optional RS-485 Modbus RTU communication enables integration into centralized lab automation platforms for remote monitoring and SPC-driven process validation. No proprietary software installation is required; exported data is natively compatible with Excel, JMP, and Python-based statistical analysis pipelines.

Applications

• Routine quality control of ferrous/non-ferrous alloys, sintered metals, and powder metallurgy compacts in foundry and aerospace manufacturing.
• Failure analysis labs preparing fracture surfaces, weld zones, and heat-affected regions for SEM-EDS or EBSD characterization.
• Academic and R&D facilities conducting comparative studies of grain growth, phase transformation kinetics, or corrosion product morphology under standardized mounting conditions.
• Third-party testing laboratories performing accredited metallographic examinations per ISO/IEC 17025 requirements, where procedural consistency and data traceability are mandatory.
• Electronics packaging labs embedding brittle intermetallic compounds or thin-film substrates prior to cross-sectioning and FIB-SEM imaging.

FAQ

What types of embedding resins are compatible with the AXQ-5?
Thermosetting resins only—phenolic, epoxy, and diallyl phthalate (DAP). Thermoplastic resins (e.g., acrylics) require cold-mounting systems and are not supported.
Is the AXQ-5 suitable for mounting soft or low-melting-point materials?
Yes—precise low-temperature control (down to 0 °C offset, typical minimum operating setpoint ~25 °C) allows safe embedding of polymers, solder joints, or babbitt metals without thermal degradation.
Does the system support regulatory compliance for pharmaceutical or medical device testing?
While primarily designed for metallurgical use, its auditable parameter logging, protocol locking, and deterministic cycle repeatability align with foundational elements of FDA 21 CFR Part 11 when deployed within validated SOPs and supporting documentation.
Can the AXQ-5 be integrated into an automated sample prep line?
Yes—via optional RS-485 Modbus RTU interface or discrete I/O signals for start/stop, cycle completion, and fault status—enabling synchronization with robotic arms, conveyor systems, or upstream cutting stations.
What maintenance is required for long-term reliability?
Annual verification of thermocouple calibration, pneumatic filter replacement, and visual inspection of mold sleeve sealing surfaces. No lubrication or hydraulic fluid servicing is needed due to oil-free pneumatic actuation.
