Case Studies for Vacuum Heat Treatment Solutions

2. LPC Vacuum Furnace for Retaining Rings & Snap Rings Dongbo developed a low-pressure vacuum carburizing furnace for Jilin Ande Electrification Technology Co., Ltd. to improve the performance of retaining rings and snap rings. These components need to maintain a balance between surface hardness and core toughness to ensure durability under demanding conditions. See More
2. LPC Vacuum Furnace for Aircraft Engine Parts Aircraft engine components, such as gears and spindle bearings, require precise heat treatment due to their exposure to high stress, friction, and demanding operating conditions. To address this challenge, Dongbo worked closely with the Institute of Metal Research, Chinese Academy of Sciences (IMR), supplying a low-pressure vacuum carburizing furnace designed for processing critical engine transmission parts.

2. LPC Vacuum Furnace for Aerospace Bearings Ensuring the durability of aerospace engine bearings isn’t a simple task. These components must handle high rotational speeds, extreme temperatures, and continuous mechanical stress. Any weakness in material properties can lead to performance degradation or even failure. Hence, Harbin Bearing Group Co., Ltd. and Xinchang Jingyi Bearing Co., Ltd. chose our low pressure vacuum carburizing furnace to refine their heat treatment process. See More
2. Hardness Gradient Flexible Control for RV Reducer RV reducers are widely used in robotic systems and precision machinery, where they must handle continuous stress and high torque. To ensure durability, the gear surfaces need to be hard enough to resist wear, while the core must remain tough enough to absorb impact. Achieving this balance is a challenge in heat treatment, especially for components that operate in high-speed automation environments. See More
2. High Temperature Carburizing Furnace for Transmission Gear Traditional carburizing methods can be slow and inefficient, especially for large locomotive transmission gears that require deep surface hardening. Tianjin Teek Transmission Co., Ltd. was facing two major issues: long processing times and surface oxidation, both of which increased production costs and affected final product quality. See More
2. Vacuum Carburizing and Carbonitriding Furnace for Precision Parts Precision parts manufacturing demands strict material performance, especially for components exposed to constant friction, heavy loads, and repetitive motion. Zhejiang Xunaye Precision Manufacturing Co., Ltd. and Nantong Jucheng Electromechanical Manufacturing Co., Ltd. needed a reliable heat treatment process to ensure their parts met high durability and performance standards. See More
2. Vacuum Carburizing Furnace for Titanium Alloys Titanium alloys are widely used in high-performance industries, including nuclear energy, aerospace, and defense. While these materials offer low weight, high strength, and excellent corrosion resistance, their low surface hardness and limited wear resistance have been major limitations in expanding their applications. To overcome these challenges, we developed a low-pressure vacuum carburizing furnace for titanium alloys. See More
