Polyurethane ISO Press Mold for PTFE Molding

Polyurethane ISO Press Mold for PTFE Molding

PTFE has a high melting point, high melt viscosity, and is shear sensitive in the amorphous state and prone to melt fracture. Therefore, conventional thermoplastic molding methods such as melt extrusion and injection molding cannot be used, and only similar powders can be used. Metallurgical methods are used for sintering.

The filling of PTFE can be preformed by plunger, free sintered or extruded. The above methods are generally suitable for products with a certain wall thickness, and are not suitable for processing PTFE films.

(ptfe film) In recent years, more mature processing technologies include calendering for dispersible PTFE resins, metal turning for PTFE sintered products with low hardness and good toughness, and conventional extrusion methods and extrusion processing in calcining methods , The resin is directly processed as a raw material without melt plasticization.

In addition to the above-mentioned one-time processing technologies, there are also some newly developed secondary processing technologies that deserve attention, such as PTFE vacuum forming technology, thermocompression molding and hot blow molding technology, and isostatic pressing molding processing technology. Teflon is the material of choice for corrosion-resistant linings, suitable for corrosion-resistant pipes, fittings, bellows, pumps, valves, kettles, storage tanks, towers and various standard equipment; as machinery, petrochemical, transportation, textile and construction industries The sealing material is widely used; Teflon can also be used as valves, bearings, piston rings, guide rails, etc. Corrosion-resistant and low-friction parts; according to the PTFE film treatment, it has selective gas permeability and can be used as a separation material to selectively pass gas or liquid, especially to filter corrosive liquids; due to PTFE has excellent biocompatibility In recent years, many people have conducted in-depth research as biomaterials.

 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.
