LOOMIS PRODUCTS ISOSTATIC WET BAG PRESSES
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
