Isostatic molding was invented years ago for the processing of ceramic and metal powder.
Subsequently, it was also applied to the granular powder of PTFE, which is inserted in a closed flexible mold to which hydrostatic pressure is then applied through the use of a fluid generally inserted in a metal container.
The uniform and constant application of pressure throughout the cycle time and its uniformity, along the entire shape of the mold, lead to a semifinished with exceptional and uniform physical properties.
Isostatic molded tubes are therefore a semi-finished product preferred to high-end machine sealing components such as lip seals, gaskets, scrapers and other parts for the hydraulic and pneumatic industry.
Compared to standard compression molding, this technology offers some distinctive advantages:
