Technical Centre
MRF Limited
TATA AutoComp Systems-Technical Center (TTC) would like to thank MRF Limited for the opportunity to
visit MRF plant at Trichy to conduct a 2 day workshop (7th & 8th January 2022)
The main scope of the workshop is to study and understand “36 inch Tyre Curing Press Machine” and
come out with cost optimization Ideas for the areas as mentioned below :
We at TTC are fully committed to aligning with expectations of MRF Limited requirements. Our
proposed services, leverages our global experience, deep engineering legacy, accelerated scalability in
handling similar scale of engagements in this domain.
