Sinter-HIP

The SINTER-HIP furnace combines sintering and hipping in one chamber capable of producing final products/components starting with complex precision parts. It aims to produce high value-added metallic, oxide and non-oxide ceramics materials with near 100% density at a economical cost. 

Research Issue  

  • Improve mechanical properties of powder processed components suitable for structural applications.  
  • Develop high performance, low cost near net shape metallic, carbide and ceramics materials via SINTER-HIP.
  • Develop fine grain structures for specific application.
  • Study the relationship among properties, dimensional stability, voids and process parameters. 


Technical Highlight

  • Presently, work on superalloys components indicates that the voids have been reduced and further improvement is still on-going.
  • Shape retention is similar to conventional sintering.

Benefits

The key advantages of SINTER-HIP lie in its ability to produce final/complex parts that are:

  • In one process (sintering first & then immediately following the HIPing in the same chamber)
  • Porosity free
  • Fine grain structure & improved properties
Applications
  • SINTER-HIP is able to process high value-added metallic, oxide and non-oxide ceramic materials/components typically used in aerospace, military, oil & gas, automotive, electronics, marine and other PE industries. 
  • SINTER-HIP is presently used to process superalloys to minimise the voids which are present in the as-sintered materials.
