HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Bangladesh, shipping to Chattogram port with onward movement to Dhaka, Narayanganj and Gazipur. We supply solid PTFE spheres from 5 mm to 310 mm, primarily for textile processing, pharmaceutical and chemical dosing applications.
Why buyers in Bangladesh source PTFE balls from HEMSUN
Bangladesh runs one of the world’s largest textile dyeing and finishing sectors, and dyeing is among the most check-ball-intensive processes in industry — dye liquor, caustic, peroxide and acid all circulate through dosing pumps continuously. The country also has a strong pharmaceutical manufacturing base with clean-service requirements. Proximity to India is a genuine advantage here: transit is short compared with sourcing from East Asia or Europe, and shipment sizes can be smaller and more frequent without the freight economics breaking down.
Industrial clusters
- Dhaka, Gazipur and Narayanganj textile belt
- Chattogram port and EPZ
- Savar and Ashulia industrial areas
- Narsingdi dyeing cluster
- Comilla EPZ

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.
