Hot pressing was an early approach for the consolidation of hard materials, initially tungsten carbides and related carbides. Early successes arose with hot pressing cemented carbides during the 1920s . Added heat and pressure were effective in densifying powder, and when coupled to spark sintering, this gave a means to consolidate high

Ultra High Temperature Furnaces For ultra high temperature requirements, MRF has several furnace capable of continuous operating at 3000°C (5430 F). Not many materials can handle these extreme temperatures, hot zones are available in Graphite or Tungsten.
vacuum oil quenching furnace and vacuum gas quenching furnace. Vacuum oil quenching furnace and vacuum gas quenching furnace is relatively common, many customers always hesitate between the two, do not know which is better.The following for you to analyze the advantages and disadvantages of the two types of vacuum furnace, convenient for you to understand.
The furnace material is made of high purity alumina polycrystalline fiber and the furnace body uses double layer shell structure which can grantee the temperature of the shell surface less than 60 ℃. Side-opening door structure is designed for ensuring the safety of use, which will shut the power when the door open. Temperature Control System ：
The vacuum hot-pressing furnace is a type of periodic operation, which is widely used for hot-pressing and sintering of cemented carbide, functional ceramics and powder metallurgy under high temperature and high vacuum conditions, as well as hot-pressing and sintering under gas-filled protection.
Of these technologies the most well known is resistance sintering (also called hot pressing) and spark plasma sintering, while electro sinter forging is the latest advancement in this field. Electro sinter forging is an electric current assisted sintering (ECAS) technology originated from capacitor discharge sintering.
