HEMSUN ENGG. INDUSTRIES is a PTFE ball manufacturer located in Dahegam, Gandhinagar district, Gujarat. Gandhinagar buyers get the shortest possible supply chain: direct factory pickup or same-day local delivery of solid PTFE balls from 5 mm to 310 mm and hollow PTFE balls made from fusion-welded hemispheres.
Why buyers in Gandhinagar, Gujarat source PTFE balls from HEMSUN
Gandhinagar district covers the Kalol, Chhatral and Dahegam industrial belts along with the pharma and engineering units around the capital, and our plant sits inside that belt on the Zak-Vahelal road in Dahegam. For local buyers this removes the two things that usually slow a PTFE ball order down: sample exchange and inspection. A local customer can bring a worn ball to the factory, have it measured against our gauges, watch the grinding operation and leave with a quotation the same visit.

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.
