According to the invention a material made from powders and of the liquid phase sintering type is first vacuum sintered to substantially full density, except for the presence of occasional closed clean flaws, and then, without lowering the temperature below the solidus, is subjected to gas pressure of 100-1000psi for 15-60 minutes for the purpose of healing the flaws.
Zhuzhou Ruideer Pm Equipment Manufacturing Co., Ltd. is best Sinter HIP Furnace, Gas Pressure Sintering Furnace and Vacuum Sintering Furnace supplier, we has good quality products & service from China.
Vacuum Hot Press Furnace Products Application: The equipment is mainly used for pressure heating sintering process in vacuum or protective atmosphere in universities, research institutes and other gold compounds, inorganic ceramics, nanomaterials, etc. to obtain high-density products, such as high-precision silicon-washed ceramic bearings.
Vacuum hot press is one of pressure sintering methods. Powders are packed in a carbon mold and then sintered with heat and pressure applied simultaneously. Degassing is performed in an initial stage of heating, and sintering is subsequently performed in an inert gas atmosphere.
Professional High Temperature Sintering Furnace, Hot Isostatic Pressing Equipment Fast Cooling Sinter HIP Furnace Automatic Control For Cemented Carbide High Temperature Tungsten Sinter HIP Furnace High Density With Rapid Cooling
Vacuum mechanical pressure sintering furnace is a combination of vacuum, hot forming, high temperature sintering function, mainly used in powder metallurgy industry, ceramic industry forming and sintering process.
Hot Isostatic Pressing Furnace HIP (Hot Isostatic Press) is an advanced sintering technology and combines debinding, sintering and densification into an integrated cycle. Identical pressure is carried on specimen under high temperature and high pressure.
The hot isostatic pressing furnace, contained within the pressure vessel, provides the heat required either from direct radiation, gas convection, or forced-gas convection. Within the furnace are electrical resistance heating elements and a space for placing the work piece (tooling and components to be HIPed).

Sintering is an elevated temperature treatment done in a furnace utilizing a protective atmosphere. The process can be done at atmospheric pressure or in vacuum furnaces. PM parts can be manufactured in several ways: the standard method as previously described and powder forging which takes a sintered preform and hot forges it to almost wrought material density.
Vacuum hot press is one of pressure sintering methods. Powders are packed in a carbon mold and then sintered with heat and pressure applied simultaneously. Degassing is performed in an initial stage of heating, and sintering is subsequently performed in an inert gas atmosphere. Heating up to 2000 ℃ is possible.
Description High vacuum sintering furnace is mainly applied for sintering processes of tungsten alloy, magnetic, heavy alloy, moly alloy, cemented carbide and ZrO blacken treatment. Technical Features 1. The furnace uses special hot zone structure and heating element design, which features temperature uniformity. 2.
HIP (Hot Isostatic Press) is an advanced sintering technology and combines debinding, sintering and densification into an integrated cycle. Identical pressure is carried on specimen under high temperature and high pressure.
Hot Isostatic Pressing. Hot isostatic pressing is a sintering process that exerts an isotropic gas pressure on the powder during the heating process and achieves densification by the combined effects of high temperature and high pressure .
