HEMSUN ENGG. INDUSTRIES supplies factory-direct PTFE balls to Vadodara from our plant in Dahegam, about 110 km away by road. We manufacture solid PTFE spheres from 5 mm to 310 mm plus hollow PTFE balls, serving the Nandesari, Makarpura, Por and Savli industrial estates and the wider Koyali petrochemical belt.
Why buyers in Vadodara, Gujarat source PTFE balls from HEMSUN
Vadodara is built around heavy process chemistry — the Gujarat Refinery at Koyali, the Nandesari chemical estate and a long tail of specialty chemical and agrochemical plants. These sites run high-temperature, high-purity and highly corrosive duties simultaneously, and they specify PTFE check elements where a metal ball would either corrode or contaminate the product. Vadodara also hosts serious process-equipment engineering, so we get a steady stream of drawing-based enquiries for non-standard diameters and tighter-than-catalogue tolerances.

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.
