In materials science research, metal processing manufacturing, and third-party testing institutions, the preparation of metallographic samples is a crucial step before microscopic analysis. For many busy laboratories, sample mounting is often a bottleneck in efficiency. Traditional manual or single-station mounting machines are not only time-consuming but also highly dependent on the operator's skill, easily leading to inconsistent sample preparation quality and even rework in subsequent grinding and polishing steps due to human error.

In the daily work of materials laboratories, we often face a tricky dilemma: the need to perform heat treatment or coating on ultra-thin samples (such as crystals, semiconductor wafers, and fuel cell substrates) in a high-temperature environment (300℃-500℃), but traditional mechanical fixing methods can easily cause stress damage.

Are you looking for a laboratory heating plate that offers uniform heating and precise temperature control? The Shenyang Kejing HEATER Series—comprising the HEATER-250 and HEATER-3040 models—features an integral cast aluminum alloy heating plate and a core microcomputer-based temperature control system, achieving a precision of up to ±1°C. Characterized by rapid heating rates and high resistance to thermal shock, these units are specifically engineered for the precise heating, baking, and drying of temperature-sensitive materials such as crystals and semiconductors.

In laboratories, research facilities, and industrial settings, high-temperature heating equipment is essential for many heat treatment and materials research processes. The most common types of high-temperature furnaces are laboratory tube furnaces and box furnaces. They differ clearly in structure, heating method, sample suitability, temperature control, and application areas. Understanding these differences makes it easier to choose the right furnace for specific experimental needs.

Common heating elements for a high temperature laboratory furnace​ include resistance wire, silicon carbide rods, and molybdenum disilicide rods. Each type has a different temperature tolerance, which directly affects the furnace’s safety and service life. To ensure long-term, stable operation, the recommended continuous working temperature is usually set lower than the element’s maximum temperature to avoid overheating and premature aging. When selecting a furnace, it is important to match the heating element and furnace specifications to both the required maximum temperature and the actual long-term operating temperature of the experiment.
