ITO Target Cold Isostatic Pressing Molds

ITO Target Cold Isostatic Pressing Molds

The use of ITO target

ITO targets are widely used in various industries, and its main applications are divided into: flat panel display (FPD) industry, such as thin film transistor display (TFT-LCD), liquid crystal display (LCD), electroluminescence display (EL), Electro-organic light-emitting flat-panel display (OELD), field emission display (FED), plasma display (PDP), etc.; photovoltaic industry, such as thin-film solar cells; functional glass, such as infrared reflective glass, anti-ultraviolet glass such as curtain wall glass, automobile, Anti-fog windshields, light shields, and glass-type disks on aircraft are three major domains. However, it is mainly used in flat panel displays. It is the main raw material for sputtering ITO conductive films. Without its existence, many materials will not be able to achieve normal processing and design. ITO film is also widely used in liquid crystal display glass, curtain wall glass and anti-fog windshield on aircraft and automobile due to its transparency to visible light and good conductivity.

Cold isostatic pressing

The cold isostatic pressing method is to put the pre-formed blank into the rubber sheath and immerse it in the high-pressure liquid to make it bear isotropic pressure, so as to realize the strengthening of the density of the green blank. Cold isostatic pressing is only to obtain the green body with the highest possible density, which makes the sintering and densification of the green body easier. Since cold isostatic pressing does not have the sintering ability of hot isostatic pressing, a vertical sintering process is required to fire the green body.

Cold isostatic pressing can press large-sized targets, and is currently the preferred molding method for most companies. Internal and external forming studies have shown that cold isostatic pressing can produce high-quality blanks that meet the requirements of ceramic targets. Moreover, when pressing blanks of different sizes, it is necessary to prepare pre-pressing molds of different specifications, and the mold cost is relatively low. However, due to the limitation of the size of the chamber, the cold isostatic pressing will cause very expensive equipment investment, and there will be deformation problems when the green body is thinner and larger in size.

Jiangsu High Industry on the research and development and production of high-performance polyurethane isostatic pressing molds. Through in-depth cooperation with many isostatic pressing equipment manufacturers and in-depth study of the industry, the developed isostatic pressing polyurethane mold series products have the characteristics of long service life, high precision, small deformation, easy demoulding, etc., and are widely used in ceramics, etc. Static pressing mould, cemented carbide isostatic pressing mould, rare earth permanent magnet material isostatic pressing mould, graphite isostatic pressing mould, etc.
