HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in Gujarat and supplies Mumbai and Navi Mumbai direct from the factory. We produce solid PTFE spheres from 5 mm to 310 mm and hollow PTFE balls, serving Taloja, TTC Rabale, Dombivli, Ambernath and Ambarnath MIDC estates as well as the valve and pump OEM base across the metropolitan region.
Why buyers in Mumbai and Navi Mumbai, Maharashtra source PTFE balls from HEMSUN
Mumbai is where a large share of India’s valve OEMs, chemical trading houses and process equipment builders are based, so the city buys PTFE balls in two very different modes. OEMs need repeatable batch supply against drawings for products they are assembling; plants in Taloja, Dombivli and Ambernath need maintenance spares for corrosive dosing duty. Mumbai buyers also frequently purchase through intermediaries, which adds cost without adding capability — buying direct from a factory that runs its own molding, sintering and grinding removes that layer and makes traceability straightforward.

Quality Assurance, Testing Protocols & Traceability
- Dimensional CMM Profilometry: Critical diameters, concentricity, and sphericity are verified on coordinate measuring machines against drawing nominals.
- Dielectric Breakdown Voltage Testing: High-voltage spark testing screens moulded parts for micro-voids, pinholes, and internal conductive inclusions before dispatch.
- Specific Gravity & Density Verification: Water displacement density checks according to ASTM D792 ensure full preform compaction and complete oven gel sintering.
- Certificate of Compliance & MTR: Every dispatch includes mill test certificates confirming raw resin lot traceability, filler content, and tensile/elongation values.
Installation, Machining & Maintenance Recommendations
- Tooling Geometry for Machining: Use polished tungsten carbide (C2 grade) or polycrystalline diamond (PCD) inserts with high positive top rake angles (15° to 25°) and sharp cutting edges to prevent material smearing.
- Feed & Speed Rates: High spindle speeds (200 to 450 m/min) combined with moderate feed rates (0.05 to 0.15 mm/rev) ensure mirror surface finishes without localized frictional heating.
- Coolant Application: Water-soluble synthetic coolants or clean air blast prevent thermal expansion during high-speed CNC turning and milling passes.
