WEIYEE XQ-2B Series Hot Mounting Press

Overview

The WEIYEE XQ-2B Series Hot Mounting Press is an engineered solution for reproducible, high-integrity metallographic specimen encapsulation in metallurgical, materials science, and quality control laboratories. Utilizing thermosetting resin compression molding under controlled heat and pressure, the system consolidates irregular or fragile samples—such as small castings, wire sections, powder compacts, or brittle intermetallics—into standardized cylindrical mounts compatible with automated grinding, polishing, and microscopy workflows. Each variant (XQ-2B 22, 30, 45, and 50) is dimensionally optimized for specific specimen diameters (Φ22 mm to Φ50 mm), ensuring uniform resin flow, minimal void formation, and edge retention during subsequent sectioning. The press operates on a robust manual hydraulic actuation mechanism, eliminating pneumatic dependencies while delivering consistent compressive force across cycles. Integrated digital temperature regulation (±1 °C stability) and programmable timing (1–99 min) enable precise replication of curing profiles required for epoxy, phenolic, and acrylic resins—critical for minimizing thermal distortion and interfacial delamination.

Key Features

• Digital dual-control interface for independent setpoint adjustment of temperature (room temperature to 200 °C) and curing duration
• Manual hydraulic pressure system with calibrated force feedback, eliminating reliance on external air supply or electric actuators
• Four standardized mounting cavity options (Φ22 mm, Φ30 mm, Φ45 mm, Φ50 mm) housed in interchangeable, corrosion-resistant steel dies
• Uniform heating via embedded cartridge heaters with PID-controlled thermal zoning, ensuring axial and radial temperature homogeneity within ±1.5 °C
• Thermal insulation jacket and safety interlock lid switch prevent operator exposure during operation and auto-disable heating if opened mid-cycle
• Compact footprint (W × D × H ≈ 320 × 380 × 420 mm) suitable for benchtop integration in ISO/IEC 17025-accredited labs

Sample Compatibility & Compliance

The XQ-2B series accommodates a broad spectrum of metallic, ceramic, and composite specimens—including ferrous and non-ferrous alloys, sintered powders, coated substrates, and fracture surfaces—without requiring pre-embedding support fixtures. Its hot-mounting process meets the dimensional and surface integrity requirements specified in ISO 16819 (metallographic specimen preparation), ASTM E3 (standard guide for preparation of metallographic specimens), and GB/T 9445 (non-destructive testing personnel qualification). All models are constructed using RoHS-compliant materials and feature CE-marked electrical subsystems. For regulated environments, the digital controller logs timestamped cycle parameters (temperature, time, operator ID if integrated with lab network), supporting GLP/GMP audit readiness and traceability per FDA 21 CFR Part 11 when paired with validated LIMS interfaces.

Software & Data Management

While the XQ-2B operates as a standalone instrument with local digital controls, its temperature and timer settings are fully exportable via RS-232 serial interface (optional adapter) for integration into centralized laboratory data management systems. Cycle logs—including start time, target temperature, actual peak temperature, dwell duration, and cooling confirmation—can be archived in CSV format for QA documentation. No proprietary software is required; raw data streams conform to Modbus RTU protocol for seamless ingestion into SCADA or ELN platforms. Firmware updates are performed via USB port using signed binary files, ensuring version control and cybersecurity compliance in multi-user facilities.

Applications

• Routine metallographic mount preparation for optical and electron microscopy (SEM/EDS, BSE imaging)
• Quality assurance of weld joints, heat-affected zones (HAZ), and additive manufacturing builds
• Failure analysis of fractured components where edge preservation and resin infiltration depth are critical
• Preparation of abrasive or porous samples (e.g., carbide tools, thermal barrier coatings) prior to precision sectioning
• Standardized specimen fabrication for inter-laboratory round-robin testing under ISO/IEC 17043 schemes
• Education and training labs requiring repeatable, low-maintenance embedding protocols

FAQ

What resin types are compatible with the XQ-2B series?
Phenolic, epoxy, and acrylic thermosetting resins—both standard and fast-cure formulations—are supported. Resin selection must align with recommended cure temperatures (typically 150–180 °C) and dwell times specified by the resin manufacturer.
Is vacuum assistance available for void reduction?
No. The XQ-2B series relies on optimized pressure application and resin viscosity management; vacuum-assisted mounting requires separate vacuum chamber integration, which is not natively supported.
Can the unit be operated continuously for high-throughput labs?
Yes—designed for duty cycles up to 12 hours/day. Thermal management includes forced-air cooling between cycles and automatic thermal cut-off at 220 °C to prevent overheating.
Are replacement dies and consumables available globally?
Standardized die sets (Φ22/30/45/50 mm), resin cups, and heater cartridges are stocked by authorized WEIYEE distributors in North America, EMEA, and APAC regions, with lead times under 10 business days.
Does the system meet NIST-traceable calibration requirements?
Temperature sensors are factory-calibrated against NIST-traceable references; optional annual recalibration services include certificate issuance compliant with ISO/IEC 17025 Clause 6.6.
