HEMSUN ENGG. INDUSTRIES supplies PTFE balls to Coimbatore’s pump and motor manufacturing cluster, covering SIDCO Kurichi, Peelamedu, Singanallur and Ganapathy. We manufacture solid PTFE spheres from 5 mm to 310 mm to drawing, in the repeat OEM batch quantities that pump builders need.
Why buyers in Coimbatore, Tamil Nadu source PTFE balls from HEMSUN
Coimbatore manufactures a very large share of India’s pumps and motors, and pumps are one of the highest-volume end uses for PTFE check balls anywhere. A reciprocating, dosing or diaphragm pump needs a check sphere that seats consistently thousands of times per hour without swelling, sticking or contaminating the fluid, and PTFE handles that across a wider chemical range than any elastomer. For Coimbatore builders the deciding factor is not whether PTFE works — it is whether the supplier can hold roundness and diameter across every batch, because an out-of-round check ball shows up as a failed pump on the test bench.

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.
