ZXQ‑4S Fully Automatic Metallographic Specimen Mounting Machine

Product parameters:

The ZXQ-4S is a fully automatic, electric metallographic specimen mounting press featuring an automatic water-cooling system. It is specifically designed for the hot mounting of small, irregularly shaped, or difficult-to-clamp metal workpieces. The resulting mounted specimens are uniform and well-formed, facilitating subsequent grinding and polishing processes and enabling microscopic analysis of the material's microstructure.
The machine can prepare up to four specimens simultaneously and supports three mold sizes: φ22mm, φ30mm, and φ45mm (with a φ30mm mold included as standard). It offers a controllable temperature range of 35–200°C, with adjustable holding times (pressure and temperature) of 1–99 minutes and cooling times of 0–60 minutes. With a power rating of 4600W and a 220V/50Hz power supply, the unit weighs approximately 75kg and measures 450×350×470mm; it comes in a dedicated export-grade wooden crate, meeting the requirements for both domestic laboratories and international shipping.

The equipment integrates the entire process—automatic heating, pressurization, timed curing, and water cooling—transitioning automatically from molding to cooling and shutting down once cooling is complete. Upon opening the top cover and pressing the "up" button, the finished specimens are automatically ejected, making retrieval effortless and minimizing manual intervention. This ensures high efficiency in batch processing, short molding cycles, and consistent specimen quality across batches.
Note: This machine is compatible only with thermosetting mounting materials (such as phenolic resin powder) and cannot be used with thermoplastic materials. The temperature system is programmable, providing automatic control to minimize human error in parameter settings.
Widely used for component failure analysis, inspection of micro-components, and metallographic sample preparation of irregular workpieces, this machine is suitable for factory quality control centers, materials laboratories, and university research institutions. It serves as a core piece of equipment for the initial mounting stage of the metallographic sample preparation process.
