Vacuum Furnace Replacing Salt Bath Furnace
Oxidative corrosion is one of the fatal defects of products. Many companies use salt furnace quenching for heat treatment of many products. When the rainy season comes every year, the parts must be surface treated within a week. Otherwise, the residual salt will lead to corrosion of the workpiece...
Vacuum furnace for mould heat treatment
In the past, the main means of mould heat treatment were heating in medium-temperature and high-temperature salt bath furnace, grading isothermal cooling and tempering in low-temperature alkali bath and nitrate bath. However, there are many shortcomings in heating salt bath furnace: toxic barium ...
Vacuum Brazing of Insulation Cup
What tailless vacuum technology? The traditional insulating cup is made of two layers inside and outside, and vacuum is pumped in the middle to insulate heat transfer. So there is an exhaust tail at the bottom of the cup gallbladder. This exhaust tail is very easy to be damaged. Therefore, taille...
Heat Treatment of 2311 Die Steel
2311 die steel is the steel grade of DIN material standard in Germany. The material has excellent mechanical properties and good machinability. It is mainly used in the processing and production of plastic mould in hot working die. The material has been pre-hardened when it leaves the factory by ...
Brazing Material of Diamond
Diamond is a kind of polymeric form of carbon element, isomer, the actual composition is carbon, and graphite, carbon black is the same, belongs to non-metal. Diamond brazing can be defined as non-metallic brazing. This kind of brazing is very difficult. In order to solve this problem, some alter...
