Why Manufacturing Is Shifting to India
Manufacturing growth in India is managed by many strong factors:
- A skilled and stable workforce
- Government support for electronics, EV, and industrial production
- Better infrastructure and new industrial parks
- Global companies adopting the “China+1” strategy
- Improved supply-chain and logistics connectivity
However, this growth is not equally distributed all over states. It is centered in specific industrial groups that provides the strong ecosystems, suppliers, and ready-to-operate facilities. These groups create compatible demand for automation components.
Major Manufacturing Clusters in India
Below is a clear, cluster-by-cluster explanation of the regions shaping India’s manufacturing future, along with the typical industries and sensor applications found in each area.
