Manufacturing process
Fabrication of PFA Ball relies on high-tonnage powder compaction and free sintering of PFA. Preforms are pressed under strict pressure dwell parameters, then heat-treated above 342°C in forced-convection ovens to bond resin granules into a void-free, chemically resilient matrix.
Material selection notes
Physical performance of PFA Ball is governed by high-grade PFA polymer formulation. Outstanding chemical resistance, high elongation (up to 400%), and low surface energy make it ideal for aggressive chemical pumps, valve seating, and pharmaceutical sanitary process lines.
How to specify your order
Procurement checklist for PFA Ball: Specify outer dimensions (OD/ID/Length), chemical exposure media, temperature limits, and target delivery schedule. We assist in selecting the optimal virgin or filled material grade and provide itemized pricing with lead times.
Quality checks and inspection
Our quality department inspects PFA Ball using precision coordinate measuring machines, digital surface roughness testers, and resin specific gravity balances, ensuring 100% adherence to customer drawing nominals.
Ordering and export documentation
Domestic PFA Ball orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Air and sea freight packing with desiccant and shock protection for international buyers Contact info@hemsun.com or sales@hemsun.com with your balls specification.
Export packing and lead time
Global shipments of PFA Ball are handled by our dedicated export logistics team. Orders are packed in heavy-duty seaworthy packaging with VCI anti-corrosion barrier wrapping and dispatched with complete IEC customs documentation.
Storage and handling
Assembly recommendations for PFA Ball: Use non-metallic insertion tools to press components into tight bores. Store stock in climate-controlled shelving away from direct heat sources.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Diameter and sphericity are verified on calibrated gauges and the achieved grade is recorded on the inspection report; sintered density is checked per ASTM D792. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
Frequently Asked Questions
Why is PFA Ball considered higher purity than PTFE Ball for semiconductor use?
PFA is melt-processable — producing a denser, smoother, non-porous surface with fewer PTFE fine particles generated during valve cycling. In semiconductor ultra-high-purity applications, PTFE compression-molding porosity and particle generation are concerns; PFA's melt-processed surface eliminates this, making PFA Balls the industry standard for semiconductor chemical delivery valve balls.
What is the largest PFA Ball you manufacture?
We manufacture PFA Balls up to 310mm diameter.
What is the difference between PFA Ball and FEP Ball?
Both are melt-processable fluoropolymers with similar chemical resistance. PFA has a higher service temperature (+260°C vs FEP's +200°C) and is considered the higher-purity choice for semiconductor WFI and pharmaceutical applications. FEP is transparent; PFA is semi-transparent. Both available from HEMSUN in 5mm to 310mm diameter.
