Cold Isostatic Presses

Cold Isostatic Presses (CIP) - Basic functions

ABRA Fluid, one of the largest manufacturers of Cold & Hot Isostatic Presses introduces its Cold Isostatic Press Production Unit (CIP). Cold Isostatic Presses (CIP) are used for diving powder consisting of ceramics, plastic or metal of a flexible form into a water-filled pressure vessel and have it optimal pressed by an effective pressure generated on all sides.
Powder formed material is transformed like this to shaped blanks which contain an enough high density for standing the following working processes. Basic materials for Cold Isostatic Pressing can be either metals, ceramics, polymers or compounds. The advantages with Cold Isostatic Pressing are based on:

punkt    no contamination by lubricant with the pressed forms

punkt    fabricating a blank without using a binder, or

punkt    fabricating a blank by using a powder with low density coefficients,

both of the latter can easily be precompressed for the process of Hot Isostatic Pressing.

By using the Cold Isostatic Process the manufacturing of homogeneous and nonporous blanks can be guaranteed. Unfinished parts fabricated like this show the very same mechanical characteristics in all three dimensions of the workpiece.

During the successive process of sintering the whole cross-sectional area of the part will be shrunken evenly. In very rare cases the end dimension of workpieces manufactured like this has to be reworked.

Cold Isostatic Presses (CIP)

Cold Isostatic Presses (CIP) of medium to large size are mainly used by our customers in manufacturing industry in a 3-shift operation.

In the field of research these presses provide the possibility of development of resources and their applications within sectors like e.g. automobile industry, space technology etc.

Laboratory Cold Isostatic Presses are especially appreciated at universities and development departments of industrial companies.
