MESA segment moulds

Your TBM project is on the right track if you have high-quality segment moulds to create
perfect rings ! 

Segment moulds are designed by MESA`s experienced design team per client`s design requirements.

Production is carried out with ISO 9001 assurance in MESA Factory, one of the largest steel mould production facilities in Europe.
​
Side and front panels are processed in high-end 3D CNC machines and high-tech 3D measuring systems are used to ensure that all dimensional tolerances fit the contractual requirements.


Once the production of first set of moulds are completed, client`s representative checks the concrete dimensions and tolerances on the test ring.
​
(Test ring shown here is for Esme - Salihli High Speed Railway tunnel 41'-0" diameter)
After client`s approval, the production is finalized with two layer of epoxy painting, installation of rubber gaskets and vibrators.
​


Segment moulds are delivered to job site
pre-assembled, ready for precast segment production.
Once the precast elements reach required strength, cured segments transferred to TBM`s erector.
​
With MESA segment moulds, your team will minimize rejected precast linings and ensure a smooth production flow for TBM`s scheduled high excavation rates.
