Special Parts

Special parts, specially manufactured parts, tailored to your needs

At JIOrings, we also manufacture special parts, bespoke parts made to measure according to a plan or based on a mould or prototype. We can manufacture special components in large or small series, from different elastomers (such as blends that are homologated for water, gas, fire, food, etc.) They are parts which have specific properties such as their hardness, softness, elasticity, and strength, which can be adapted to the most testing situations, whether of temperature or climate, and which can meet the specific demands of each client.

We choose rubber as the material of manufacture for special components because there are many advantages. It is a very practical material which adapts to movement, tolerances, hardness or temperature changes. It is an electrical insulator, conductor or anti-static. It is resistant to fire, chemical agents, and to oils. It resists fire and can be self-extinguishing, among many other things.

For our special components manufactured in elastomers, we also have complete reports with their properties and standardisations, as well as their surface treatments.

In the event that you need a special part, do not hesitate to contact JIOrings so that we can look at your requirements in more detail and thus get the manufacturing process started:
