NST 1200°C Vacuum Hot Pressing Furnace
The vacuum hot-pressing furnace by vacuum tube furnace, 40 t electric compressor, quartz vacuum cavity, 1/2 inch of graphite mould, tube furnace with resistance wire Canthal A1 (Sweden) as the heating element, using double shell structure and 30 program temperature control system, phase shift trigger, thyristor control, furnace adopts polycrystalline alumina fiber materials, the hot-pressing furnace is mainly used in the preparation of dense composite materials under high pressure in a vacuum.
Software control system (choose) : this furnace is equipped with communication interface and software, can be directly through the furnace computer control of each parameter, and can be observed from the computer PV on the stove and SV temperature and the running situation, the actual temperature of the furnace curve drawing computer real time, and can keep the temperature data of each time, can call up at any time.
Open cover protection system: the furnace is equipped with a travel switch. When the cover is opened, it will automatically cut off the power and ensure the user’s safety.
Sealing system: the furnace tube and flanges are sealed with silicone o-ring, easy to remove, retractable, good air tightness, and ensure that the pressure gauge of 12 hours is not deflected.
Vacuum system (optional) : can be equipped with tw-1.5 A vacuum pump and can be pumped to 10-1pa vacuum pump or can be pumped to 10-4Pa German imported molecular pump.
Furnace material: adopt Japan imported furnace material, not drop powder, material heat preservation performance good, reflectance high, temperature field balance, anti – heat gain cold – shrinkage ability.
Heating element: using the world top resistance wire of Sweden Canthal A1 resistance wire using long, temperature field equalization.

Leakage protection function: the furnace is equipped with a leaky air switch to ensure the safety of use when the furnace leaks power.
Characteristics of hot-pressing furnace:
(1) the equipment can combine extrusion and sintering into a process to achieve high density and high strength composite materials.
(2) open type vertical heating body, furnace tube flange can coil out of the shaft.

|Temp Control Mode||Adopt the yu electric program control thermometer
1.The 30 program control temperature can only adjust PID.
2.over temperature protection is broken accidentally protection with a temperature or broken accidentally electric furnace heating circuit automatically cut OFF, and, when the temperature of the furnace more than 1200 degrees or thermocouple burn out, the main circuit of ac relay will automatically disconnect, main circuit disconnect, panel ON lights, OFF the light, the limited protection electric furnace).
3. With 485 communication interface (standard and standard for choosing software)
4. It has the function of power failure protection, that is, when the power is off, the program will not start up from the beginning temperature, but the furnace will start to rise when the power is off.
The instrument has the function of temperature self-setting
FP93 temperature controller（SHIMADEN，Japan）（optional）
1. The program control temperature can be divided into 4, 2 and 1 groups. If it is divided into 4 groups, each program is 10 paragraphs.
2. The PID control of group 6, low, medium and high temperature can be used with a set of PID, so that each temperature segment can be controlled accurately.
3. over temperature protection is broken accidentally protection with a temperature or broken accidentally electric furnace heating circuit automatically cut OFF, and, when the temperature of the furnace more than 1200 degrees or thermocouple burn out, the main circuit of ac relay will automatically disconnect, main circuit disconnect, panel ON lights, OFF the light, the limited protection electric furnace).
4. The meter has the degree of Fahrenheit (F) and Celsius (C)
5. With a 485 communication interface (with the selection of software)
6. Automatic stop function
7. You can store multiple sets of programs and use them in any way you want.
8. It has the function of power failure protection, that is, when the power is off, the program does not start up from the beginning temperature, but the furnace temperature starts to rise from the power failure.
9. The instrument has output power, the number of segments and the execution time of the program, the display of temperature, temperature and cooling status of the program.
10. The meter has the function of skipping (that is, the meter can jump this step and carry out the next step directly.
11. The instrument has the function of temperature self-tuning.
