XQ-4Z Automatic Hot Mounting Press by WEIYEE

Overview

The XQ-4Z Automatic Hot Mounting Press by WEIYEE is an industrial-grade thermal embedding system engineered for reproducible, high-integrity specimen encapsulation in metallurgical, materials science, and quality control laboratories. It operates on the principle of thermosetting resin consolidation under controlled heat and uniaxial hydraulic pressure—enabling void-free, edge-retentive mounting of metallic, ceramic, polymer, and composite specimens. Designed for routine use in ISO/IEC 17025-accredited labs and manufacturing QC environments, the XQ-4Z delivers consistent cycle repeatability across batched sample preparation workflows. Its fully automated sequence—comprising programmable heating ramp, dwell time at setpoint temperature, pressure application, cooling initiation, and synchronized depressurization—eliminates operator-dependent variability inherent in manual or semi-automatic presses.

Key Features

• PLC-controlled industrial touchscreen HMI with intuitive graphical interface for parameter programming (temperature setpoint: ambient to 200 °C typical range; pressure: adjustable up to 12 MPa; cycle duration: 3–15 min configurable)
• Integrated water-cooling circuit with flow monitoring—ensures rapid, uniform post-cure thermal dissipation and prevents resin degradation or specimen distortion
• Hydraulic actuation system with closed-loop pressure feedback, enabling precise force application and automatic pressure hold/release without manual valve intervention
• Dual-mode operation: supports both standard hot mounting (using phenolic, epoxy, or acrylic resins) and optional low-temperature vacuum-assisted mounting for porous or temperature-sensitive samples
• Interlocked safety enclosure with door position sensor and emergency stop circuit compliant with IEC 60204-1 electrical safety standards
• Modular die cavity design accommodating standard mounting diameters: Φ25 mm, Φ30 mm, and Φ40 mm—each with precision-machined alignment guides and corrosion-resistant steel construction

Sample Compatibility & Compliance

The XQ-4Z accommodates a broad spectrum of specimen geometries and material classes—including irregularly shaped metallographic sections, brittle fracture surfaces, coated substrates, and multi-layered electronic components—without requiring pre-trimming or excessive fixturing. Its uniform radial pressure distribution minimizes edge pull-out and resin-starved zones, directly supporting ASTM E3, ISO 15510, and GB/T 9445-compliant microstructural analysis requirements. The press meets CE marking directives for machinery (2006/42/EC) and electromagnetic compatibility (2014/30/EU). For regulated industries, its deterministic process logging (via optional RS485/Modbus RTU output) enables traceability aligned with GLP and GMP documentation practices, including audit-ready cycle records (timestamp, temperature profile, pressure curve, dwell duration).

Software & Data Management

While the base configuration utilizes embedded PLC logic with local HMI interaction, the XQ-4Z supports digital integration via industry-standard communication protocols. Optional Modbus RTU or Ethernet/IP interfaces allow connection to laboratory information management systems (LIMS) or MES platforms for centralized cycle logging, remote parameter validation, and SPC-driven process monitoring. All operational events—including temperature deviations >±2 °C, pressure instability >±0.3 MPa, or cooling flow interruption—are timestamped and stored in non-volatile memory for ≥10,000 cycles. Data export is supported in CSV format for post-process statistical evaluation (e.g., Cp/Cpk analysis per ISO 22514-2), satisfying internal QA review and external accreditation audits.

Applications

• Preparation of cross-sectional specimens for optical microscopy (OM), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS)
• Routine quality assurance of sintered powder metallurgy parts, weld joints, and additive-manufactured components
• Embedding of abrasive or friable samples (e.g., concrete, rock cores, catalyst pellets) prior to diamond grinding and polishing
• Standardized mounting for hardness testing (Vickers, Rockwell, Knoop) per ASTM E384 and ISO 6507
• Encapsulation of PCB traces, solder joints, and thin-film devices for failure analysis and delamination assessment

FAQ

What mounting diameters does the XQ-4Z support?
The system accepts standard mounting molds with internal diameters of Φ25 mm, Φ30 mm, and Φ40 mm—each interchangeable without tooling change.
Is water cooling mandatory for operation?
Yes. The integrated water-cooling system is essential for thermal management during and after compression; continuous flow (≥2 L/min at 15–25 °C inlet) is required to maintain cycle integrity and die longevity.
Can the XQ-4Z be validated for ISO 17025 compliance?
Yes. With optional calibration-certified temperature and pressure transducers, plus audit-trail-enabled data logging, the system supports full metrological validation per ILAC-G8 and ISO/IEC 17025:2017 clause 6.4.3.
Does it support vacuum-assisted mounting?
Vacuum assistance is available as a factory-installed option (XQ-4Z-VAC variant), enabling resin infiltration into high-porosity or cracked specimens prior to thermal curing.
