1.Cold Isostatic Press
Cold Isostatic Presses use a pressure vessel chamber to compact a powder or material placed in a sealed tooling, bag or other container. Under high pressure, materials are formed and densified with a high and uniform density.

2.The application of Isostatic Press
Now isostatic press is widely applied to industrial ceramic powder forming, high temperature refractory, hard metals,permanent magnetic material & rare metal powder molding, PTFE, crystal and so on.

3. Forming method
1.One-step forming: Powder placed into rubber mould,then rubber mould put into pressure vessel of CIP to be pressed.
2.Two-step forming: Powder pressed by normal press firstly, then preforming products packed by  Vacuum packaging machine, then put them into CIP to be pressed with a high and uniform density.
 
4.CIP's features
♦ Products pressed by CIP are featured with high & well-proportional density and small contraction after sintering.
♦ CIP can form products with long rod shape and cylindrical shape that are difficult to be formed by conventional compression moulding.
♦ Pressed products have high-strength and workability, and internal stress is decreased sharply.
♦ Mold is easy to be made and with long life and low cost.
♦ CIP can press big-size products and can press products with different shape in one time.
 
5.Our advantages
 High safety
Frame, pressure vessel and pressurization vessel are all winded by pre-stressed steel wires, its designed life is over one million working cycles. The worst breaking way is that some steel wires are broken,so no possibility of serious accidents.

High reliability
All high-pressure oil pipelines are in structure members, which eliminates potential dangers that  high-pressure liquid is ejected from pipelines, and all of the high pressure oil pipes need not to be maintained at regular intervals.
The main factor threatening reliability of CIP is impurity left in pressure vessel by users. The impurity would jam oil pipelines, wear valves and even break hydraulic pump, which will cause product faults. We resolve this problem by three measures.
The First Measure:
There is the strainer in pressure vessel to filter relative big impurity.
The Second Measure:
Powder can go through strainer, but our CIP's high pressure oil pipelines are short and with big aperture, so it isn't easy to be jammed by powder; and structure and materials of high pressure valve can well bear powder or impurity.
The Third Measure:
Different from traditional CIP which's working medium and drive medium are isolated by vulnerable rubber membrane,our CIP's working medium and drive medium are isolated by plunger,so impurity in working medium has no possibility to enter posterior pressurization system. It avoid that impurity causes serious accidents.

Wearing parts are just seal rings
Our composite bearing seal technique is that different bearing seals work at different pressure phases. As bearing parts of CIP, replacement of bearing  seal ring is very simple: NO need professional maintenance personnel and 15 minutes can finish replacement.
Super-high pressure valves have low fault rate, and its replacement is very easy.
 In the traditional isostatic press technology, the super-high pressure valve is wearing part and replacement is very complex. Our super high pressure liquid-control unidirectional valve is patented technique with low fault rate. Its valve seat and valve body are separated design. When valve goes wrong, the end user only need to replace valve seat without the presence of manufacturer personnel.
