Vacuum Hot Press Sintering Furnace
Model：JZM-1200
Overview:
Vacuum hot pressing sintering furnace is a device that combines vacuum, atmosphere, hot pressing and high temperature sintering, and is suitable for high temperature hot forming of new materials such as powder metallurgy and functional ceramics. For example, it is used in vacuum sintering of metals such as transparent ceramics, industrial ceramics, and alloy materials composed of refractory metals, and high-temperature sintering of ceramic materials silicon carbide and silicon nitride. Heat treatment at temperature, the purpose is to increase its strength through metallurgical bonding between particles.
Main Structure Introduction:
Vacuum hot pressing furnace is composed of furnace body, furnace cover, heating and heat preservation and temperature measurement system, vacuum system, air charging system, water cooling system, control system and pressurization system.
Furnace Body: double-layer 304 stainless steel water-cooled structure, precision polishing, beautiful appearance.
Heating insulation and temperature measurement system: The heating system adopts domestic resistance wire to ensure temperature uniformity. The thermal insulation material is made of domestic furnace material, which does not drop powder, has good thermal insulation performance, high reflectivity, balanced temperature field, and strong resistance to thermal expansion and contraction. It adopts thyristor temperature control, equipped with PID function instrument, digital display meter, with over-temperature sound and light alarm function, and PLC touch screen automatic control can also be used, and historical data is retained to facilitate the analysis of the sintering process.
Vacuum system: It is composed of mechanical pump, inflation valve, air release valve, vacuum valve, vacuum pressure gauge, bellows, vacuum pipeline and bracket.
Gas filling system: It is composed of various pipes and valves, and an explosion-proof system is optional. When the pressure in the furnace is higher than the safe value, the gas will be automatically released. A needle valve is installed on the inflatable pipeline, and a flowmeter can be selected to control the inflated amount, which is used for the argon gas and nitrogen gas atmosphere required by the sintering process. Vacuum hot pressing sintering furnace laboratory new material high temperature thermoforming experimental furnace.
The structure design of this equipment is advanced and reasonable, the furnace body is made of all stainless steel, the surface is brushed, beautiful and atmospheric, the electrical components are made of well-known brands at home and abroad, fully automated program control, the control system software is developed by our company, and the man-machine interface operating system, The screen is friendly, the operation is simple, the response speed is fast, and the working conditions in the furnace can be monitored in real time, and the system is stable and reliable. This equipment is widely used in colleges and universities, scientific research units and production enterprises to hot-press and sinter materials under vacuum, protective atmosphere or air (indenter and mold need to be replaced with SiC). The vertical structure is suitable for annealing, brazing, sintering and degassing of materials under vacuum, inert atmosphere and high temperature conditions. It is an ideal equipment for material laboratories.

Temperature Control Method
Adopt Jinzhengmao program temperature control instrument (standard)
1. 30-segment program temperature control intelligent PID adjustment.
2. With over-temperature protection and couple-break protection, the heating circuit of the electric furnace will be automatically cut off when the over-temperature or couple is broken, (when the temperature exceeds 600 degrees or the thermocouple is blown, the AC relay on the main circuit will be automatically disconnected, limiting the protection of the electric furnace ).
3. With 485 communication interface (standard when purchasing software)
4. It has the function of power-off protection, that is, when the furnace is powered on after power-off, the program does not start to rise from the initial temperature, but from the time of power-off, the furnace temperature starts to rise.
5. The instrument has the function of temperature self-tuning
(Replacement of imported instruments requires additional payment, optional)
