In metal, ceramic, composite materials, and laboratory sample preparation, sanding and polishing is a common and essential step. While the process may look simple, improper methods often lead to remaining scratches, uneven surfaces, low efficiency, or even sample damage.
This High Temperature Box Furnace, with its ultra-large 125L capacity and a maximum temperature of 1700℃, is an industrial-grade laboratory furnace that is becoming a powerful tool for numerous university laboratories, research institutes, and industrial enterprises in overcoming the challenges of high-temperature material preparation.
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.

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.

In materials science research and industrial production, laboratories often face a dilemma: choosing a tube furnace to obtain excellent atmosphere protection and vacuum environment, or choosing a box furnace to achieve sintering of large-sized or large-batch samples?
In the field of materials science, the success of an experiment depends not only on the performance of a single piece of equipment, but also on the compatibility and smoothness of the entire experimental process. As a veteran brand established in 2000, Shenyang Kejing understands the pain points of scientific researchers: they need not only to buy equipment, but also to buy the right solution.
