HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Sri Lanka via Colombo port. We supply solid PTFE spheres from 5 mm to 310 mm for textile processing, rubber and latex manufacturing, food processing and water treatment applications.
Why buyers in Sri Lanka source PTFE balls from HEMSUN
Sri Lanka’s industrial demand centres on apparel and textile processing, rubber and latex products, tea and food processing, and a growing water treatment sector. Textile dyeing and latex compounding are both chemical dosing intensive, which is where PTFE check spheres are consumed. Transit from India to Colombo is among the shortest export routes we run, which means replenishment can be frequent and small without freight economics becoming unfavourable.
Industrial clusters
- Colombo and Katunayake export processing zones
- Biyagama industrial zone
- Horana and Kalutara industrial belt
- Kandy and central province processing
- Hambantota industrial zone

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.
