CNC turning of polyurethane and rubber

CNC SEAL MANUFACTURING

Did you know that polyurethane
and rubber can also be turned?

The production of sealing elements from polyurethanes, rubbers, elastomers and plastics is traditionally carried out by injection moulding.
This method is very efficient for large series, however, smaller or only piece production cannot be practically realized by this technology, mainly for time and economic reasons.

However, we can machine these materials on a specialized CNC lathe, which brings a number of advantages:

✅ Flexibility – Ideal for producing smaller batches or bespoke individual pieces.

Speed of production – Seals can be produced within hours if required

✅ Fast preparation – No need for expensive moulds, reducing initial investment and speeding up the process

✅ Precision and repeatability – CNC technology enables high precision in machining complex shapes

✅ Material diversity – A variety of materials can be machined efficiently, including special elastomers.
We can turn material from a hardness of 70 Sh.A

✅ Dimensional options – We can handle production up to 500 mm diameter

If you need to deal with the production of seals, we will be happy to help you find the optimal solution.
