YANRUN YXQ-5 Intelligent Automatic Hot Mounting Press

Overview

The YANRUN YXQ-5 Intelligent Automatic Hot Mounting Press is a benchtop, fully automated thermosetting embedding system engineered for high-throughput, reproducible metallographic sample preparation. It operates on the principle of hot compression molding—applying controlled heat and hydraulic pressure to consolidate thermosetting resins (e.g., phenolic, epoxy, or acrylic) around metallic, ceramic, or composite specimens. This process encapsulates irregular, fragile, or dimensionally unstable samples into standardized cylindrical mounts—typically 30 mm in diameter—with precise dimensional repeatability and minimal edge rounding or void formation. The YXQ-5 is designed for laboratories requiring consistent, operator-independent mounting prior to grinding, polishing, and optical or electron microscopy analysis. Its integrated water-cooling system enables rapid thermal quenching post-compression, reducing cycle time without compromising resin cross-linking integrity or specimen integrity.

Key Features

• PLC-based intelligent control architecture with a full-color touchscreen HMI, supporting menu-driven parameter configuration for temperature, dwell time, pressure ramping, and cooling duration.
• Hydraulic pressure actuation ensures uniform, repeatable force application (typically 10–15 MPa range, compliant with ASTM E3-22 and ISO 15510 standards for mount quality).
• Interchangeable hardened steel mold sleeves (standard Φ30 mm; optional Φ40 mm and Φ45 mm) allow flexible specimen throughput without hardware reconfiguration.
• Programmable heating profile with 0–300 °C range and ±1.5 °C thermal stability, calibrated per ISO/IEC 17025 traceable procedures.
• Automated vertical sample elevation via hydraulic cylinder, enabling safe, contact-free insertion and ejection—critical for minimizing operator exposure during hot-cycle operations.
• Intelligent water-cooling module with programmable timer and flow monitoring, preventing thermal shock while ensuring complete resin polymerization before demolding.

Sample Compatibility & Compliance

The YXQ-5 accommodates all common metallurgical specimens—including ferrous/non-ferrous alloys, sintered powders, coated substrates, and brittle intermetallics—provided they are compatible with thermosetting resin embedding. It is not suitable for thermoplastic resins or low-melting-point materials (e.g., soft solders or polymers below 80 °C). The system meets general safety requirements per IEC 61010-1 for laboratory electrical equipment and incorporates overtemperature cutoff, pressure relief valves, and emergency stop functionality. While not certified to UL or CE as a standalone unit, its control logic and thermal management align with GLP-compliant workflows when operated within documented SOPs. All embedded samples comply with ASTM E3-22 Section 6.2 (mounting quality criteria) and ISO 15510 Annex A (dimensional tolerance specifications for standard mounts).

Software & Data Management

The embedded PLC firmware supports audit-trail-capable operation logging, including timestamped records of setpoints (temperature, time, pressure), actual process values, and operator ID (via optional login module). Data export is available via USB port in CSV format for integration into LIMS or QA documentation systems. Although no proprietary PC software is bundled, the system’s Modbus RTU interface (optional RS-485 expansion) permits integration with third-party SCADA platforms for centralized lab equipment monitoring and 21 CFR Part 11–compliant electronic record retention when paired with validated middleware.

Applications

• Routine quality control of castings, weldments, and heat-treated components in foundries and aerospace manufacturing.
• Failure analysis laboratories preparing cross-sections of electronic packages, solder joints, and thin-film devices.
• Academic and R&D facilities conducting microstructural correlation studies (e.g., grain size vs. mechanical properties) requiring >50 identical mounts per batch.
• ISO/IEC 17025-accredited testing labs performing hardness mapping or phase quantification where mount geometry directly affects indenter alignment and measurement uncertainty.
• Forensic metallurgy workflows requiring chain-of-custody–aligned embedding cycles with full parametric traceability.

FAQ

What types of embedding resins are compatible with the YXQ-5?
Thermosetting resins only—phenolic (black/brown), epoxy (transparent), and acrylic (fast-cure clear) formulations. Thermoplastics (e.g., PVC, polyethylene) are incompatible due to lack of cross-linking under pressure and risk of cold flow during polishing.
Can the YXQ-5 be used for vacuum impregnation?
No. This is a compression-only hot mounting press. Vacuum-assisted infiltration requires a separate vacuum-pressure impregnation station, which is not integrated or supported.
Is calibration documentation provided with the unit?
A factory calibration report covering temperature sensor accuracy (±1.5 °C at 150 °C) and pressure transducer linearity (±2% FS) is included. Full ISO/IEC 17025 calibration services are available upon request through authorized YANRUN service partners.
What maintenance is required for long-term hydraulic system reliability?
Biannual inspection of hydraulic fluid level and seal integrity is recommended. Use only ISO VG 32 anti-wear hydraulic oil; replacement interval is 24 months under typical lab usage (≤10 cycles/day).
Does the YXQ-5 support multi-step ramp-and-soak temperature profiles?
No. It implements single-setpoint heating with adjustable dwell time. Complex multi-zone thermal profiles require external programmable ovens or specialized embedding systems.
