Moulding
Five lines under one roof: DISA MATCH 130 high pressure moulding, ARPA 450, ARPA 1300, a no bake fast loop and no bake floor moulding for the heaviest work.
Foundry Infrastructure
at Arasur, Coimbatore
Five moulding lines, six induction furnaces, a core shop, two sand plants, a CNC machine shop of more than forty machines, a metallurgical lab and two coordinate measuring machines - all on one 523,200 sq ft site at Arasur, Coimbatore, Tamil Nadu, India. Installed capacity is 1,500 tonnes a month.
Plant Areas
What Is Actually
Inside the Plant?
Six working areas sit inside one 523,200 sq ft site at Arasur, Coimbatore. Moulding, melting, cores, sand, machining and inspection are all run by Technocast, not subcontracted.
Melting
Six induction furnaces. Four 1-tonne dual-track units in the main bay run about 60 tonnes a day; two 1.5-tonne units rated 1,750 kW serve the no bake bay.
Core Shop
Five cold box core shooters from 5 kg to 30 kg, a 5 kg shell core shooter and a four-table CO2 station, so cores are made to the same schedule as the moulds.
Sand Systems
Two dedicated sand plants. Green sand is prepared for the high pressure line, while a 30 t/hr continuous mixer and two 100 t hoppers feed no bake moulding.
Machine Shop
Over 40 CNC machines: 20 VMCs, four horizontal machining centres, five vertical turret lathes, 13 turning centres, gear cutting and dynamic balancing.
Lab and Metrology
Chemistry is checked on every heat by optical emission spectrometer. Two Brown & Sharpe CMMs, sand testing and mechanical testing complete the inspection loop.
