Overview
The YANRUN ZXQ-2 Automatic Hot Mounting Press is an industrial-grade thermosetting specimen mounting system engineered for precision and repeatability in metallographic sample 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 irregular, fragile, or dimensionally unstable metallic or ceramic specimens. This process yields dimensionally stable, edge-retentive mounts with minimal void formation and thermal distortion, enabling subsequent sectioning, grinding, polishing, and high-magnification microstructural analysis under optical or electron microscopy. Designed for integration into ISO/IEC 17025-accredited metallurgical labs and QC environments, the ZXQ-2 supports standardized workflows aligned with ASTM E3, ISO 15510, and GB/T 13298—ensuring compliance with international metallographic practice guidelines.
Key Features
- Full-digital PID temperature control: Integrated intelligent digital thermostat with dual-display interface—simultaneously showing setpoint and real-time chamber temperature—with ±1.5 °C accuracy across the 0–200 °C range.
- Pneumatically actuated press mechanism: Energy-efficient linear motion system delivering consistent axial pressure (adjustable via external regulator) without mechanical wear or hydraulic fluid maintenance.
- Non-conductive injection-molded housing: Flame-retardant ABS enclosure providing electrical insulation, chemical resistance to common mounting resins, and ergonomic access to mold cavity and control panel.
- Programmable curing cycle: Timer with 1-second resolution allows precise definition of heating dwell, compression hold, and cooling phases—critical for optimizing resin crosslinking and minimizing interfacial shrinkage.
- Acoustic process monitoring: Built-in audible alarm signals completion of cycle, temperature deviation beyond tolerance, or abnormal pressure drop—supporting unattended operation during batch processing.
Sample Compatibility & Compliance
The ZXQ-2 accommodates non-standard geometries including wire fragments, powder compacts, fractured surfaces, thin foils, and multi-material assemblies—common in failure analysis, additive manufacturing QA, and coating adhesion studies. Its Φ25/Φ30/Φ40 mm interchangeable mold system ensures compatibility with standard metallographic consumables (e.g., Struers, Buehler, and Leco mounting cups). All operational parameters—including time, temperature, and pressure—are logged internally and exportable for audit trails. The system supports GLP-compliant documentation when paired with optional PC-based data logging software, meeting traceability requirements under ISO 9001 and FDA 21 CFR Part 11 (when used with validated electronic records configuration).
Software & Data Management
While the ZXQ-2 operates as a standalone instrument with front-panel controls, its digital controller features RS-232 serial output (optional cable available) for connection to laboratory information management systems (LIMS) or custom SCADA platforms. Exported logs include timestamped entries for each cycle: start time, target temperature, actual peak temperature, applied pressure, total duration, and alarm status flags. No proprietary software is required; raw CSV-formatted data can be parsed using standard spreadsheet or statistical analysis tools. For regulated environments, validation protocols—including IQ/OQ documentation templates—are available upon request from YANRUN Technical Support.
Applications
- Routine preparation of ferrous and non-ferrous alloy specimens for ASTM E112 grain size analysis
- Mounting of sintered PM parts and ceramic composites prior to hardness testing per ISO 6507
- Encapsulation of corrosion-exposed coupons for cross-sectional evaluation of oxide layer integrity
- Stabilization of brittle intermetallic phases and weld HAZ regions for FIB-SEM site-specific lift-out
- High-throughput mounting in automotive casting QA labs where cycle consistency directly impacts downstream image analysis repeatability
FAQ
What types of mounting resins are compatible with the ZXQ-2?
Phenolic, epoxy, and acrylic thermosetting resins—both standard and low-expansion formulations—are fully supported. Resin selection must align with specimen thermal sensitivity and final application requirements (e.g., conductivity for EBSD, hardness for microhardness testing).
Is a compressed air source included with the unit?
No. The ZXQ-2 requires an external clean, dry, oil-free air supply regulated to 0.5–0.8 MPa. A quiet diaphragm-type air pump (model ZP-10A) is offered as optional accessory.
Can the ZXQ-2 be used for cold mounting?
No. This is a dedicated hot mounting press. Cold mounting applications require separate vacuum-impregnation or hydraulic cold press systems.
Does the machine support automatic mold ejection?
Manual mold removal is standard. Optional motorized ejection module (part no. ZXQ-EJ1) is available for integration into automated sample prep lines.
What safety certifications does the ZXQ-2 carry?
The unit complies with GB 4793.1 (Chinese equivalent to IEC 61010-1) for electrical safety in laboratory equipment. CE marking is not applicable as it is manufactured for domestic and export markets under OEM agreements requiring customer-specific certification pathways.
