HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Vietnam, shipping to Ho Chi Minh City (Cat Lai), Hai Phong and Da Nang. We supply solid PTFE spheres from 5 mm to 310 mm for textile processing, chemical, electronics and general manufacturing use.
Why buyers in Vietnam source PTFE balls from HEMSUN
Vietnam’s manufacturing expansion has created demand faster than local component supply has developed, and PTFE balls are a clear example — the country runs a very large textile dyeing and finishing sector plus growing chemical and electronics manufacturing, but has limited domestic PTFE sphere production. Textile processing is the single largest driver, since dye liquor, caustic and peroxide dosing circuits consume check spheres continuously. Indian supply is competitive here on both cost and transit compared with European sourcing.
Industrial clusters
- Ho Chi Minh City industrial zones
- Binh Duong and Dong Nai provinces
- Hai Phong industrial zones
- Hanoi and Bac Ninh manufacturing belt
- Da Nang industrial area

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.
