Polyurethane Isostatic Pressing Molds for PTFE Molding

Polyurethane Isostatic Pressing Molds for PTFE Molding

Typical characteristics and properties of PTFE

PTFE is available in granular, fine powder and water-based dispersion forms.

Granular PTFE resin is produced by suspension polymerization in an aqueous medium with little or no dispersant. Granular PTFE resin is used primarily for molding (compression and isostatic pressing) and plunger extrusion.

PTFE fine powder is prepared by controlled emulsion polymerization, and the product is white fine particles. Fine PTFE powder can be processed into flakes by paste extrusion or used as an additive to increase the wear resistance or friction properties of other materials.

PTFE dispersions are prepared by aqueous phase polymerization with stirring using more dispersant. Dispersions are used in coatings and film casting.

As mentioned above, PTFE has excellent properties such as chemical inertness, thermal resistance (high and low temperatures), electrical insulation properties, low coefficient of friction (static 0.08 and dynamic 0.01) and performance over a wide temperature range (260 to 260 °C ) - and therefore suitable for a wide range of applications.

Jiangsu High Industry focuses on the research and production of isostatic pressing moulds, customizes various dry bag and cold isostatic pressing moulds, adapts to different models of various manufacturers at home and abroad, and deeply understands the needs of various industries. Alloy, graphite and other industries provide high-performance isostatic pressing mold rubber sleeves.

Product overview: Isostatic pressing rubber mold is used for the molding of ceramic materials, tungsten and molybdenum materials, graphite materials, refractory materials, and alloy powders. It can be customized according to drawings, and can be designed according to samples.

Product features: The deformation of the elastic mold under the pressure of the liquid medium is transmitted to the powder in the mold. The friction between the powder and the mold wall is small, the blank is uniformly stressed, and the density distribution is uniform, and the pre-pressed blank is encapsulated. In the elastic rubber mold, it is put into the high-pressure cylinder after sealing, and the green body is compressed and formed by liquid transfer.

Product advantages: The design of the mold cover is reasonable to ensure no water leakage, the blank is well formed, and the service life is long, including the fixture for processing the blank, which can be customized! There is a free amount of open steel molds.

We support all kinds of customization, if you need it, please contact us.
