HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Indonesia, shipping to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya) and Batam. We supply solid PTFE spheres from 5 mm to 310 mm in virgin and filled grades for palm oil processing, mining, refining and chemical duty.
Why buyers in Indonesia source PTFE balls from HEMSUN
Indonesia’s PTFE ball demand is shaped by three heavy industries that rarely appear together elsewhere: palm oil processing, mineral and coal mining, and refining. Palm oil refineries run bleaching, degumming and fatty acid processing where hot acid and organic media defeat elastomer check elements. Mining brings abrasive slurry dosing, where filled PTFE or UHMWPE outlasts virgin grade. The archipelago’s geography also means buyers value consolidated shipments, since internal distribution adds meaningful cost.
Industrial clusters
- Jakarta — Cikarang, Bekasi, Karawang industrial estates
- Surabaya and East Java industrial belt
- Batam free trade zone
- Sumatra palm oil processing belt
- Kalimantan mining and coal belt

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.
