PTFE Balls Supplied in Kolkata
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.
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.

Why Buy Direct From the Factory
We mold, sinter, turn, grind and inspect every ball in our own plant. That is the whole difference between us and a trading intermediary — the die, the sintering cycle and the tolerance are all answerable to you.

Manufacturing precision polymer spheres in India since 1990.
No trader margin
You buy from the party that actually makes the ball, at factory pricing.
5 mm to 310 mm
Including large diameters most suppliers cannot produce void-free.
Drawing-based work
In-house die fabrication for custom diameters, tolerances and features.

PTFE Balls in Kolkata — FAQ
Is it economical to buy PTFE balls from Gujarat for a Kolkata plant?
Usually yes, because the freight cost on a consignment of polymer spheres is small relative to the trading margins that normally sit between an eastern India buyer and a manufacturer. Consolidating into fewer, larger shipments improves it further.
Do you supply large-diameter PTFE balls for heavy equipment?
Yes. We manufacture solid PTFE spheres up to 310 mm, which covers large valve and tank float applications that most suppliers cannot produce at all.
How long is delivery to Haldia or Howrah?
Road or rail transit generally runs four to six days once dispatched. We confirm the specific date with the quotation, including whether the diameter needs a dedicated die.
