Mainly used in stainless steel and iron-based powder metallurgy injection molding (MIM), cemented carbide, superalloy, high specific gravity alloy, cermet, magnetic material, carbide, boride, oxide, intermetallic compound, pre-sinter oxide vacuum or The carrier is degreased (wax).
The application of brazing technology is indispensable. In order to meet the needs of the rapid development of current technology, our company has developed vacuum brazing equipment suitable for different needs. The other dimensions of the equipment can be supplied to the special product according to the user’s requirements, hydrogen brazing furnace, or can also be designed to set up the furnace (upper discharge or lower discharge structure)

ADVANTAGES
1, Configure fast cooling system to improve product quality, shorten production cycle and increase production efficiency
2, Degreased sealed furnace and grease traps reduce furnace wall, heat shield and heating body contamination, degreasing and fat collection more effectively
3, Special sealing furnaces help to improve the uniformity of the furnace. Directional air degreasing, enhanced degreasing effect, more complete degreasing
4, Efficient vacuum dewaxing/degreasing device can effectively avoid the pollution of vacuum pump. This technology has been declared and passed the utility model patent.

Vacuum Brazing Furnace
Product Features and Special Configuration
A special sealing furnace is installed in the heating chamber to minimize the contamination of the grease on the furnace wall and the insulation material in the heating chamber.
The control system is equipped with alarm functions such as overheating, overpressure and water cutoff. The system can be automatically processed as needed to reduce equipment damage and ensure personnel safety
The device is fully automatic, automatic and manual operation can be free from interference switches, equipment vacuum, temperature and heating power can be automatically recorded, you can view the data in the production process at any time.
The device is controlled by a combination of a touch screen and a programmable logic controller (PLC) for easy and intuitive operation.
The main components of the control system are joint ventures such as Schneider, Siemens or ABB to minimize the failure rate.
Temperature control system using Island Power / British Continental, Japan
Vacuum brazing not only saves a lot of expensive metal flux, but also eliminates the need for complex flux cleaning processes and reduces production costs.
Special material technology can be added to the low temperature convection heating device. (This is user selectable)
Low-pressure control devices to meet special atmospheric process requirements (such as inhibiting the volatilization of alloying elements).
High vacuum/medium vacuum configurations are available freely depending on material technology requirements. (This is user selectable)
