Vacuum hot press furnace combines vacuum/atmosphere, hot press molding, high temperature sintering, suitable for powder metallurgy, functional ceramics and other new materials of high temperature hot forming, such as applied to the transparent ceramics, industrial ceramics and other metal and com...
Vacuum Heat Treatment for Ring Dies
Ring die is applied for the feeding machines for processing plants, livestock farms, poultry farms, individual farmers and small and medium-sized farms, farmers or large, medium and small feed processing plants. It is a spare parts of feed processing machine that directly compresses particles by ...
Vacuum Furnace Maintenance
With the development of industry, vacuum furnace is widely used. In the long-term operation process, the vacuum furnace will produce parts failure and damage, resulting in reduced mechanical operation ability. In order to ensure the normal operation of the vacuum furnace and extend the service li...
Vacuum Furnace Touch Screen & PLC
Vacuum furnaces usually adopt Omron/ Mitsubishi/ Siemens PLC (programmable controller) in combination with Kunluntongtai/ Wecon/ Taiwan Weinview I series touch screen, which plays an important role in many process parameters and frequent interactive operation between human and machine. Low-voltag...
vacuum brazing soldering furnace
Vacuum brazing soldering furnace is a large-scale heat treatment equipment, which can carry out vacuum brazing, vacuum annealing, vacuum aging and other processing. Several different programs can be programmed, and hundreds of heat treatment curve points can be controlled and programmed. Temperat...
Vacuum heat treatment for gear parts
Gear parts are important components of the reducer, and its quality directly affects the service life and safe production of the reducer. After the emergence and use of gear processing machines, the bottleneck that seriously affects and restricts the quality of gear processing occurs in the blank...
Heat treatment misunderstanding, cause and prevention of deformation
Misunderstanding of heat treatment 1. The workpiece that is quenched is not cooled to room temperature and cannot be tempered？ Some people think that after quenching, they can’t enter the tempering process when they are not cooled to room temperature. In fact, many steel grades, especially...
Advanced vacuum heat treatment can extend the life of the mold
As an indispensable and important equipment in the manufacture of machinery industry, molds are more convenient for the manufacture of similar products, and at the same time bring a certain downward adjustment to the production cost, but the heat treatment is an important processing step, the fol...
Vacuum brazing
Vacuum brazing characteristics The development of vacuum brazing technology has been seventy-six years old and has become a promising welding technology. It was first used in the electronics industry to braze copper and stainless steel parts, and later applied to the aerospace industry and the at...
