Larsen&Toubro 🇮🇳 introduced one innovative technology #ROTOTEC based on powder metallurgy in early 90's It was aimed at maintenance of precious machine elements in machine tools.Low temp thermal spray based on powder metallurgy(additive manufacturing) #Google can't search now

This process was utilized for repairs later in 1993. Godrej Press brake connecting crack has been built effectively thus avoiding (prevented) full blown down time for a critical machine.It was the only machine factory had to press cross members and corner posts of ISO Marine Containers.Later Cincinnati machine arrived in 1994 as standby.
