Manufacturing process
Our manufacturing route for Food Grade FDA PTFE begins with precision die compaction of granular PTFE fluoropolymer resin under sustained tonnage. Following preform ejection, parts enter multi-zone circulating air sintering ovens where temperatures dwell at 365°C–375°C to achieve full gel coalescence. Components are cooled at controlled rates to optimize crystalline fraction and mechanical stability.
Material selection notes
The chemical resilience of PTFE fluoropolymer ensures Food Grade FDA PTFE remains completely impervious to corrosive chemicals, steam, and industrial fuels. Its low frictional properties reduce torque requirements in valve assemblies and prevent galling against mating metal faces.
How to specify your order
To configure Food Grade FDA PTFE for your application, submit component dimensions, operating PV factors, and delivery port requirements. Our engineering team prepares complete technical evaluations and formal quotations within 24 hours.
Quality checks and inspection
Every batch of Food Grade FDA PTFE undergoes stringent quality checks at our Dahegam plant: laser micrometer diameter scanning, surface roughness profilometry (Ra ≤ 0.2 µm), and tensile/elongation testing per ASTM D4894 to ensure complete material coalescence.
Ordering and export documentation
Domestic Food Grade FDA PTFE 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. Recurring supply schedules supported with fixed drawing revision and lot numbering for plant stores Contact info@hemsun.com or sales@hemsun.com with your PTFE components specification.
Export packing and lead time
HEMSUN ENGG. INDUSTRIES supplies Food Grade FDA PTFE to international valve and pump manufacturers globally. Export orders include comprehensive quality certificates, packing lists, and seaworthy timber boxing compliant with ISPM 15 standards.
Storage and handling
Installation best practices for Food Grade FDA PTFE: Verify housing bore chamfers (15° to 30°) prior to insertion to prevent seal shearing. Store unused inventory in original packaging in a dust-free storage area.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Moulded from FDA 21 CFR 177.1550 listed resin; the material certificate traces the resin lot behind each batch, and sintered density is checked per ASTM D792. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
