In this process, the powder is filled into a flexible form, usually rubber or polyurethane, and tightly sealed. The mold is then immersed in the liquid (water-oil emulsion) within the pressure vessel. Isostatic pressure is then exerted on the entire outer surface of the mold, which compresses the powder into a solid body (green part).

Advantages of isostatic wet bag press:

  • Uniform strength and density
  • Homogeneous microstructure
  • Uniform shrinkage
  • Complex shapes and high dimensional accuracy
  • Reduced finishing
  • Low mold cost
  • Wide variety of materials
  • Very high pressing pressures
  • Fast pre-filling and emptying times
  • Press pressures of over 400 MPa (4,000 bar)
  • Pressure vessel inner diameter: from 75mm to over 1,200 mm
  • Pressure vessel working lengths: from 300mm to over 4,000 mm
  • Press medium of the pressure vessel: Water/Oil Emulsion
  • Fully automated, programmable pressing cycle (open / open)
  • Integrated mold rack for automatic feeding/unloading of the molds
  • Variable press parameters for pressure build-up speed / pressure dwell time / decompression / holding or switching stages
  • Storage of product-specific pressing parameter recipes
  • Hydraulic lifting and closing mechanism for the upper closure
  • Automatic de-airing valve
  • Fast pre-filling and emptying of the pressure vessel via high-volume high pressure pilot operated check valve
  • Free programmable HD decompression valve (servo-controlled) enables precise and variable decompression stages
  • Selection of different high-pressure generators (HD pressure multipliers / HD triplex plunger pumps)
  • Extensive fluid reservoir and pumping systems with multiple filtration of the press fluid
  • Fully automatable press mold handling with conveyor carousel via filling station / mold washing cabin / automatic loading / unloading into / from the pressure vessel to the demolding station.
  • Easy operation via plain text instructions
  • Clear process displays
