Shenyang Dongbo Thermal Technology Co., Ltd., founded in 2017, is specialized in high-end heat treatment and smelting equipment development, production and process research and development, relying on the transformation of production, education and research achievements, with key parts heat treatment and surface modification technology and special metal smelting technology as the main research and development direction. He is now a member of the National Heat Treatment Society and the China Heat Treatment Industry Association. In 2020, he has successively become a "national high-tech enterprise" and a "fledgling eagle enterprise". In 2021, he was awarded the "national specialized, special and new small giant enterprise".

Shenyang Dongbo is committed to providing full chain services in the field of vacuum heat treatment and special smelting. Since its establishment, it has completed many national major scientific research projects, with a contract amount of more than 100 million yuan in 2020. A series of original achievements with independent intellectual property rights have been achieved by focusing on a number of key common technologies such as surface treatment, organization and property regulation and special smelting. The whole chain equipment research and development platform of "theoretical conception - equipment structure and process simulation - prototype design and manufacturing - process validation - prototype and process software optimization - system integration and debugging" has been built, more than 20 invention patents and software copyrights have been authorized, and the company has successfully passed the ISO9000-2015 and IATF16949-2016 quality management system certification.

Through continuous innovation and development, the company has established its technological advantages in major sectors. The complete set of low-pressure vacuum carburizing equipment developed has broken the long-term monopoly of foreign countries in this technical field, achieved precision carburizing under the high alloy composition system, and formed the leading low-pressure vacuum carburizing technology advantage. It is mainly reflected in: independently developed process expert system, carbon flux dynamic setting technology, hardness gradient flexible control technology, high temperature carburizing technology and unattended intelligent system. The developed equipment has been promoted to aerospace, rail transit, automobile, robot and other fields, and the cycloidal wheel of RV reducer of intelligent robot has been successively conquered Low pressure carburizing technology problems of various key components such as stainless steel ferrules for high-speed rail and high-end bearings for aeroengines. In terms of special heat treatment, key equipment such as low-temperature carbonization, chromizing nitriding and aluminizing oxidation has been developed, which has been successfully applied in the nuclear industry in China and has realized the localization of some production equipment; The advanced melting and special melting and casting equipment developed provides technical and equipment support for the performance improvement of the core components of China's aeroengine.

The company's main products can be divided into eight categories: low-pressure vacuum carburizing (carbonitriding) furnace and its production line, high-pressure gas nitriding (nitrocarburizing) multi-function vacuum furnace, vacuum heat treatment furnace and its production line, vacuum hydrogen furnace, vacuum metallizing furnace, special thermal equipment, advanced smelting and special solidification equipment, and intelligent centralized control system of vacuum thermal equipment, which can meet the market's requirements for vacuum heat treatment, surface treatment Requirements for special smelting equipment and customization.
