16～18 item / All 18 items
Compatible with all types of heat treatment processes. The built-in hot zone achieves high performance and long lifespan. Reduces operational and maintenance costs.
The Nightrex high-temperature vacuum furnace complies with the quality standards AMS2750, NADCAP, and CQI9.
Ideal for heat treatment of machined molds, tools, and other items! Heat treatment can be done with minimal finishing allowance.
Vacuum heat treatment is conducted in a vacuum atmosphere to avoid surface degradation during heating at high temperatures. It is suitable for heat treatment of machined molds, tools, and other items, as it allows for heat treatment with minimal finishing allowance. Our company offers various heat treatment options, including vacuum hardening, salt bath, and DS hard (nitriding treatment). **Features** - **Vacuum Hardening** - Maximum processing weight is 1000 kg for batch furnaces and 1500 kg for pit furnaces. - Heating can reach up to 1300°C. - **Salt Bath** - Items are heated by being immersed in molten salt. - Various treatments can be performed, from small individual items to larger ones. - **DS Hard** - A surface modification furnace that processes items in their final finishing state (sulfur immersion furnace). - Extends the lifespan of molds, tools, and more. *For more details, please refer to the PDF document or feel free to contact us.*
It is suitable for heat treatment of materials such as Ti, Inconel, and SUS thin plates, where oxidation prevention is difficult!
We would like to introduce our "Vacuum Heat Treatment." We adopt a method where all processes from heating to cooling are conducted in a heating chamber, preventing oxidation during cooling. Since vacuum is inert to metals, it is used as an ideal atmosphere, resulting in a good surface condition with excellent luster that requires little to no finishing. Additionally, the vacuum heat treatment heating is conducted solely by radiant heat, resulting in a very gentle temperature rise. This leads to a small temperature difference between the surface and the center of the treated item, allowing for uniform expansion and contraction, and enabling heat treatment with minimal distortion. 【Features】 - A vacuum pressure corresponding to 1×10−1 Pa retains 1 ppm of impurity gas. - Conducted solely by radiant heat. - The surface maintains its luster, and deformation is minimal, allowing for significant reduction in post-treatment processing. - No quenching oil is used, and there is no intrusion of oil into the chamber or vacuum furnace. *For more details, please refer to the PDF document or feel free to contact us.
