Prakash Bhai, this is a highly encouraging list that shows the massive potential of making products in India!
However, these numbers seem to only cover the cost of basic machinery. If we look at setting up a real, compliant factory, the infrastructure costs will quickly multiply this budget by three to five times.
A major chunk of money will disappear into setting up the building, safe land, and proper industrial infrastructure. Normal power lines cannot run a factory. You have to invest heavily in heavy-duty three-phase commercial lines, a dedicated transformer, and expensive industrial electrical panels and specialized wiring that can handle high voltage without burning down. On top of that, you need a massive generator backup to deal with sudden power cuts.
Safety and government rules will also eat up a lot of cash. Installing proper fire hydrant systems, alarms, and emergency exits is mandatory by law.
Getting a Factory License and a Pollution Board NOC also brings heavy compliance fees. Plus, buyers do not pay on day one. You need months of cash buffer on hand just to buy raw materials and pay workers before seeing any revenue.
A real, long lasting and sustainable manufacturing plant for anything will easily shoot past the given numbers.
