HEMSUN ENGG. INDUSTRIES supplies factory-direct PTFE balls across West Bengal, covering Howrah, Kolkata, Haldia, Kalyani and Durgapur. We manufacture solid PTFE spheres from 5 mm to 310 mm and hollow PTFE balls, for both the engineering cluster and the Haldia process belt.
Why buyers in West Bengal source PTFE balls from HEMSUN
West Bengal combines a traditional engineering and foundry cluster around Howrah and Durgapur with a heavy process belt at Haldia built on refining, petrochemicals and fertilisers. Eastern India has comparatively little domestic PTFE ball manufacturing capacity, so most regional demand is currently met through multi-layer trading out of Mumbai or Delhi. That makes the delivered price unusually high relative to factory cost, and it also means buyers rarely get direct answers about resin grade or process control.
Industrial clusters
- Howrah engineering and foundry cluster
- Haldia petrochemical belt
- Kolkata — Taratala, Dankuni
- Kalyani industrial area
- Durgapur–Asansol industrial belt
- Uluberia industrial area
