Isostatic molding enables the creation of completely voidless materials. It achieves high-quality fluoropolymer | PTFE materials.
Isostatic molding is a molding method that utilizes hydraulic pressure, named for its ability to apply hydrostatic (static) pressure uniformly (iso). Since elastic materials such as rubber are used in the molding die, it is also referred to as rubber molding.
The mold for shaping PTFE consists of one side made of a flexible membrane (such as a rubber membrane). The molding die filled with powdered raw material is submerged in water within a pressurized tank, where hydrostatic pressure is applied as the molding pressure. This is a preliminary molding method that allows the internal PTFE powder to be pressed into a non-standard shape with uniform pressure through the flexible membrane.
It results in minimal distortion during molding, enabling the creation of voidless materials, and can be used for thin-walled molding and container shapes. It is also possible to mold not only general materials but also shapes that are closer to the final product.
★ Due to the high degree of freedom in shape, it is possible to create molded products that are close to the final shape of the product.
★ The molds are inexpensive, providing advantages when producing small quantities of large components.
★ The use of hydrostatic pressure from all directions ensures uniform pressure on the molded product, allowing for the creation of voidless materials.
