HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in Dahegam, Gandhinagar district — about 35 km from Ahmedabad — and supplies the city direct from the factory with no trader margin. We produce solid PTFE balls from 5 mm to 310 mm and hollow PTFE balls from fusion-welded hemispheres, typically dispatching to Ahmedabad GIDC estates within the same week.
Why buyers in Ahmedabad, Gujarat source PTFE balls from HEMSUN
Ahmedabad runs one of India’s densest concentrations of dyes, dye intermediates and bulk-drug plants, and almost all of them move aggressive liquids — sulphuric and hydrochloric acid, caustic, solvents and chlorinated intermediates — through dosing pumps and check valves. Those duties destroy metal and elastomer check elements, which is why virgin PTFE spheres are the default replacement part across Vatva, Naroda and Odhav. Because we are inside the same industrial belt, buyers here can send a sample ball in the morning and get a matched quotation the same day.

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.
