HEMSUN ENGG. INDUSTRIES is a PTFE ball manufacturer located in Gujarat, with our plant at Dahegam in Gandhinagar district. We have manufactured solid and hollow PTFE balls in the state since 1990, covering 5 mm to 310 mm, and supply every major Gujarat industrial belt directly from the factory.
Why buyers in Gujarat source PTFE balls from HEMSUN
Gujarat accounts for a very large share of India’s chemical, petrochemical, dye and pharmaceutical output, which makes it simultaneously the country’s biggest consumer of PTFE check elements and the natural place to manufacture them. The state’s GIDC estate structure concentrates that demand into identifiable belts — Ankleshwar and Panoli for chemicals, Vatva and Naroda for dyes and intermediates, Nandesari for petrochemicals, Metoda and Shapar for pump and valve manufacturing. Being inside that ecosystem rather than shipping into it is why we can exchange samples and quote against a physical worn ball within a day for most Gujarat buyers.

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.
