The second innovation proposed by JESA is the injection process of high-end plastic TORLON® PAI. 3 years of development were necessary to validate this process and JESA is now part of the very closed circle of structures having this technological mastery, which naturally opens the scope of possibilities in the conception and production of customized bearing solutions.
Torlon® PAI is known to be the best performing thermoplastic that can be processed by injection moulding under certain conditions. It has exceptional mechanical properties combining the advantages of metals (high stiffness, low creep and very high wear resistance) as well as the advantages of thermoplastics (low density and good elongation factor). Due to its composition, it is also completely non-magnetic, dielectric and stainless.
TORLON® PAI is characterised by very high thermal stability with incomparable mechanical and chemical resistance compared to other advanced engineering plastics. The intrinsic properties of this material make it an effective alternative to metal in high-temperature friction and wear applications.
This material is usually machined, but it is also possible to shape it through a complex injection molding process. Indeed, this material is not injected like a standard polymer, very specific equipment and expertise in the field of polymers is required to maximise its properties.
This process has the advantage to provide tailor-made solutions with the possibility of making very complicated shapes. Another asset of injection overmolding is obviously the cost reduction due to the wasted machining chips saving.

Thanks to this development, Jesa can now offer to its most demanding customers a state-of-the-art material and process for developing unique innovative solutions in many fields such as aeronautics, the medical technology industry and food industry.
