It is possible to conduct tests using the equipment owned by Sun Furnace for performance verification of samples before research and development or new implementation.

The size, shape, and material of samples vary depending on the customer. When your existing equipment cannot accommodate new research and development projects or challenges in new fields, you can visit our company to see the results firsthand. 【Testing Examples】 ◆ Tests involving heating treatment with moving samples When powder is heat-treated, unevenness occurs, resulting in inconsistent sample quality. By conducting tests using a rotary kiln that moves the samples during processing, we achieved uniform heat treatment without unevenness. ◆ Tests involving heating treatment with stationary samples During heat treatment tests of powder in a rotary kiln, the powder tended to clump together significantly. To address this, we introduced a special powder container into a muffle furnace and efficiently processed the powder by directly flowing hydrogen into the container, preventing it from solidifying. Many customers are considering transitioning to a rotary kiln when heat treatment does not go well with their existing furnace. We also offer gas recommendations tailored to each sample. We are committed to addressing even your small questions and requests with full effort. With our long-standing achievements and experience as a manufacturer of industrial furnaces, we provide total support from specification determination to aftercare.

With an "atmosphere furnace" that performs heat treatment using atmosphere gases tailored to the properties of the materials, oxidation, decarburization, and improvements in material properties, as well as post-processing steps, can be carried out smoothly.

When steel undergoes heat treatment in the atmosphere, oxidation and decarburization can occur, which may necessitate surface finishing and other processing. Therefore, atmosphere furnaces are often used to fill the furnace with atmosphere gases to reduce post-processing efforts or to suppress oxidation and decarburization, depending on the application. The atmosphere gases used can vary widely based on the properties of the material and the purpose of the heat treatment, including inert gases such as nitrogen and argon, as well as hydrogen and AX gas. 【Features】 ● Gas switching is possible during heat treatment. ● There are various types of furnaces available, including batch and continuous types. ● We handle degreasing furnaces for powder metallurgy. 【Case Studies】 ■ Want to anneal aluminum without oxidation → 'Roller Hearth Annealing Furnace' ■ Want to carburize the material → 'Batch Atmosphere Gas Carburizing Furnace' ■ Want to nitrify powders → 'Retort Rotary Nitriding Furnace' If you have any new challenges or inquiries regarding energy conservation, automation, environmental considerations, or safety, please feel free to reach out.

With a rotary kiln for thermal treatment of powdered materials, it is possible to uniformly heat treat the powder while stirring, and since the temperature can also be measured, the quality is improved.

A powder material heat treatment furnace, known as a rotary kiln, is an industrial heat treatment furnace that heats and sinters powder raw materials while stirring them inside a rotating furnace core tube. This equipment can be used for the sintering, sintering, reduction, oxidation, nitriding, and drying of powder materials, including batteries. Since it stirs the powder while drying and heat treating in a rotary manner, there are no inconsistencies. There are two types of rotary kilns: "batch type" and "continuous type." The "batch type" can process mixing, drying, and heat treatment in one go. The "continuous type" can handle larger production volumes. 【Features】 ● It can accommodate 100% hydrogen due to its special gas seal structure. ● It can propose everything necessary for powder processing, including front and rear devices. ● In the batch type, gas switching is possible during heat treatment. Please consult us for small lot production, heat treatment testing, and small sample manufacturing. If you are considering transitioning from batch type to continuous furnaces due to increased processing volume, we can also propose a transition plan.

With a "tempering furnace," it is possible to improve the properties of various materials by performing heat treatment at temperatures tailored to specific purposes.

The "annealing furnace" is a furnace that heats metal materials to soften them, holds them at that temperature, and then cools them slowly to remove residual stress and achieve a uniform structure. If the processes of sintering or firing are incomplete, or if the temperature and cooling speed during shaping, the reuse of materials, and the ambient temperature have a significant impact on the thermal history, the hardness of the structure may become uneven, leading to machining irregularities. By softening through annealing treatment, the material can exhibit its original properties. Annealing is also known as "normalizing" or "annealing." 【Features】 ● Appropriate cooling control for rapid cooling, slow cooling, and over-aging is possible. ● Precise temperature distribution can be achieved. ● Various atmosphere gases can be introduced. 【Case Studies】 ■ Want to anneal copper without oxidation → "Vacuum Bright Annealing Furnace" ■ Want to fully anneal steel → "Pit Type Non-Oxidizing Annealing Furnace" ■ Want to anneal castings → "Trolley Type Annealing Furnace" ■ Want to anneal large parts of press products → "Trolley Type Annealing Furnace" / "Pit Type Annealing Furnace" ■ Want to anneal optical glass molded products → "Trolley Type Annealing Furnace"
