HEMSUN ENGG. INDUSTRIES supplies factory-direct PTFE balls to Kolkata, Howrah, Haldia and Kalyani. We manufacture solid PTFE spheres from 5 mm to 310 mm and hollow PTFE balls, serving both the Howrah engineering and foundry cluster and the petrochemical and fertiliser plants along the Haldia belt.
Why buyers in Kolkata and Howrah, West Bengal source PTFE balls from HEMSUN
Kolkata splits into a traditional engineering and foundry cluster around Howrah and a heavy process belt at Haldia built around refining, petrochemicals and fertilisers. The Howrah side buys spheres as components for valves, pumps and fabricated equipment; the Haldia side buys them as corrosion-duty maintenance spares. Eastern India is also comparatively under-served by domestic PTFE ball manufacturers, so a lot of regional demand is met through multi-layer trading — which is precisely where direct factory supply changes the delivered cost.
Industrial clusters
- Howrah engineering cluster
- Haldia petrochemical belt
- Taratala industrial area
- Kalyani industrial area
- Dankuni
