Gas Pressure Sintering GPS furnace with energy cost reducing 25%

Gas Pressure Sintering GPS furnace with energy cost reducing 25%

  Zhuzhou Ruideer Intelligent Thermal Equipment Co.,Ltd located in Ruideer Technology Park,Tianyuan District,Zhuzhou Hunan Province,founded in 2011,covering an area of more than 19,000 square meters.

   At present,Ruideer has developed two core technologies of “high temperature &high pressure”and “chemical vapor deposition” with supplying vacuum sintering furnace and CVD coating furnace.

   Our main products including:GPS furnace,MIM vacuum sintering furnace,ceramic silicon carbide/nitride sintering furnace,silicon carbide coating furnace,cemented carbide cutting tool CVD coating furnace and the turnkey solution for the cemented carbide cutting tool(From RDP powder,press machine,sinter furnace,cuuting machine,laser machine,metalgraphic testing instruments,sandblasting matchine,ultrosonic cleaning machine to CVD coating furnace).

   The Gas Pressure Sintering Furnace(GPS furnace) has been awarded National Manufacturing Champion Product,widily used in cemented carbide,non-cermets,semiconductor,aerospace,automobile manufacturing,weapons and other fields,exported to the US,Russia,Japan,EU,Ukraine,South Korea,Vietnam and other countries,which making Ruideer a well-known brand in the industry.

The main parameters for the equipment:

    The special feature of the GPS process is a sequence of dewaxing at low pressure, sintering at normal pressure and -after a status is reached with only closed pores being present in the material - sintering at a high pressure, which results in a further densification and faster elimination of the remaining pores. Therefore materials produced in the GPS technology show in general mechanical properties (hardness, strength, Weibull-modulus, fracture toughness) which are superior to those of pore-free materials produced by the conventional sintering method.

    The devices are particularly suitable for sintering such types of ceramics or metals, which tend to decomposition at elevated temperatures or which do not sinter to high densities in standard sintering operations. This process has not the limitations with respect to the shape of the manufactured parts as in hot pressing and it is also an advantageous alternative to the more costly HIP-process.

Available volume: 54 dm³ to 500 dm³ at 1650°C / 10 MPa (N2 or Ar atmosphere)

Applications of GPS plants:

Sintered silicon nitride and sialon with excellent mechanical properties (e.g. cutting tools, turbocharger rotors, engine components)
Silicon carbide (mechanically heavy strained parts in corrosive environments etc.)
Super alloys (mechanically strained parts in high-temperature applications)
Hard metals, especially cemented carbides with low content of Cobalt and for high-quality grades with optimum mechanical properties.
Composite materials in general
A very promising application of this technique is the production of serial parts made of SSN for the automobile industry.
