By performing annealing, the arrangement of the structure returns to its original state, allowing it to be used as optical glass.
A "annealing furnace" is a furnace that heats metal materials, holds them at a certain temperature, and then cools them slowly to remove residual stress and achieve a uniform structure. By softening the metal materials and equalizing the variations during machining, the materials can exhibit their original properties. Glass is significantly affected by thermal history due to temperature variations during shaping and cooling speed, so annealing allows the arrangement of the structure to return to its original state, making it usable as optical glass. 【Features】 ■ Capable of appropriate cooling control such as rapid cooling, slow cooling, and over-aging ■ Capable of producing precise temperature distribution ■ Various atmospheric gases can be introduced *For more details, please refer to the PDF document or feel free to contact us.

Company information
The manufacturing process of industrial products in all fields almost always includes a heating process. Due to the various factors such as the material, size, processing volume, temperature, atmospheric gas, and transportation method of the items being processed, heating devices, or thermal treatment furnaces, will have different specifications. Our company has traditionally responded to user expectations with a flexible design and manufacturing system. We have accumulated extensive experience and achievements across various powdered materials, including metal materials, mechanical parts, electronic components made of glass and ceramics, magnetic materials, and battery materials, regardless of the target objects. In recent years, it has become rare for thermal treatment furnaces to serve merely as heating devices; they are often required to have some additional functions. In addition to safety, energy efficiency, and automation, we actively incorporate advanced technologies to address environmental issues and enhance usability, going beyond merely following past technologies, and we will continue to create together with our customers.
