Hot pressing furnace manufacturing

Vacuum hot pressing furnace scope of application

Vacuum hot-pressing furnace is widely used in various composites, high thermal conductivity materials, SiC/Si3N4/B4C ceramics, copper-based powder materials, iron-based powder materials, iron-copper-based powder materials and other materials of parts near net forming, densification, the highest sintering temperature can reach 2500%. Such as: aircraft landing iron-copper based powder materials brake discs, EMU brake shoe, body armor, armored vehicle guard plate, helicopter bullet-proof armor and so on.
 technical characteristics
 The vacuum hot pressing furnace is horizontal, single room, cold wall and horizontal front loading structure.
 In addition to loading and unloading, all other processes fully automatic operation, digital, intelligent, without manual intervention.
 The equipment is equipped with 2bar-15bar gas pressure external circulation rapid cooling system to ensure the workpiece hot-pressing finished rapid cooling, efficient operation.
 The equipment can not only work under vacuum condition, but also under "positive pressure" H2 state and Ar state. The pressure quality of similar molding materials such as CuZnSn powder is better.
 The thermal field of the pressurized chamber is simulated and calculated by thermal simulation. The temperature uniformity is very high. The heating elements and insulation layer are optimized by modular design.
 The pressure chamber is equipped with a load-bearing frame press structure, each single or multiple hydraulic cylinders at the upper and lower parts, precisely positioned at the upper and lower centers, and pressurized in two directions.
 The manufacturing accuracy of the pressure head plane is as high as 5 m.
 Equipped with pressure sensors and weighing devices imported from Germany to ensure precise control of output pressure accuracy.
 Equipped with German import pressure displacement monitor to ensure precise control of displacement stroke accuracy.
 The constant pressure time of the head can reach 12 hours at 2400 degree high temperature, and high precision pressure maintenance is achieved.
 The computer interface of pressure numerical value and displacement is given both real-time digital and curve double display.
 The way of pressure can choose one-way compression and two-way compression.
 Pressure control mode: hydraulic motor servo control or proportional valve flow control.
 The thermal field can choose graphite heat shield and all metal heat shield.
 Loading pressure can be selected 30T, 50T, 100T, 200T, 400T, 500T, 800T, 1000T, 2000T.
 The furnace temperature can be selected at 1500, 1800, 2000, 2300, 2400, 2500, respectively.
 The material of pressing head can be chosen as isostatic pressing graphite and TZM alloy.
