3850 Series HIP Sintering
Sinterbar™ Jr. Pressure Furnace

Sinterbar™ Jr. Pressure Furnaces are vital to the efficient and economical production of a wide variety of advanced ceramics, carbide tools and wear parts, and other high performance materials. They eliminate a separate hot isostatic pressing operation for many materials with liquid phases. Overpressure capabilities permit many sinterable ceramics to be processed at higher temperature for superior properties.

The "Sinterbar" pressure furnace design allows multi‐mode operation in vacuum, partial pressures, and positive gas pressures up to 1500 psig (100 bar). Available in vertical top loading laboratory sizes with furnace temperatures range up to 1650°C for carbides and 2200°C for ceramics. For broader application in high performance engineering ceramics production, Sinterbar Jr. furnaces can be supplied with either graphite or carbon‐free hot zones for operation at tempertures to 2200°C and presures to 1500 psig (100 bar).

A complete furnace system includes all necessary controls for fully automatic operation of complete process cycles including Sweepgas™ binder removal. Sinterbar Jr. furnaces incorporate the latest developments in high temperature pressure furnace technology.


Production Benefits

  • Better Quality - Increased part densities. Improved mechanical properties.
  • Higher Yield - Eliminates need to transfer fragile debindered parts from debinder to sinter furnace.
  • Cost Savings - One-st vs. multi-step process. Reduced overall cycle time. Simplified equipment, low maintenance. Overall reduction in capital investment compared to separate sinter and HIP furnaces

Furnace Advantages

  • Multi-purpose Operation - Combines binder removal, presinter, sinter, and pressure consolidation steps in one continuous cycle.
  • Material Compatibility - Carbon-free all-metal or graphite furnace hot zones to suit product requirements.
