Manufacturing Process
PTFE Ball Manufacturing Process
Six controlled steps for solid PTFE balls from raw resin to finished sphere — all performed in-house for sizes from 5 mm to 310 mm. Hollow PTFE balls follow a separate two-hemisphere path joined by thermal fusion and chemical welding.
-
Compression Molding
Virgin or filled PTFE powder is loaded into moulds and compressed under controlled pressure to form solid pre-forms sized for the target ball diameter.
-
Controlled Sintering
Pre-forms are sintered in temperature-controlled ovens, fusing PTFE particles into a dense structure with full material properties before machining.
-
Ball Machining
Sintered billets are machined into precise spheres on dedicated ball turning equipment to achieve nominal diameter and roundness.
-
Finishing
Surface finishing brings the ball to the required smoothness for valve seats, seals, and fluid-contact applications.
-
Inspection
Each ball is measured for diameter, roundness, and surface quality against the customer drawing or agreed tolerance band.
-
Dispatch
Finished solid and hollow PTFE balls are packed for domestic or export shipment with batch traceability available on request.

FAQs
Frequently Asked Questions
Technical answers about solid and hollow PTFE balls, sizes, materials, OEM supply, and ordering.
What sizes of PTFE balls do you manufacture?
We manufacture solid PTFE balls from 5 mm to 310 mm and hollow PTFE balls to drawing by outer diameter and wall thickness. Metric and fractional inch solid sizes are catalogued on our size chart.
What is the difference between PTFE balls and Teflon balls?
Teflon is a brand name for PTFE. Both describe polytetrafluoroethylene balls. See our PTFE vs Teflon guide for detail.
Are you a PTFE ball manufacturer or trader?
We are an in-house manufacturer in Gujarat, India. Solid balls are produced through our own compression molding, sintering, and machining process. Hollow balls are built from two hemispheres joined by thermal fusion and chemical welding.
What tolerance can you achieve on PTFE ball dimensions?
From ±0.05 mm on small balls to ±0.5 mm on 310 mm sizes. See the full size chart for indicative tolerances.
Can you match a PTFE ball sample?
Yes. Send a sample with your inquiry. We measure and reproduce the reference part for evaluation before volume production.
What are PTFE valve balls used for?
Solid PTFE spheres serve as moving elements in ball check valves, relief valves, and soft-seat assemblies in corrosive fluid lines. See our PTFE valve balls guide.
Do you supply solid virgin PTFE balls?
Yes. Virgin PTFE balls from 5 mm to 310 mm — 100% non-reprocessed fluoropolymer, FDA compliant, zero porosity.
Are Teflon balls and PTFE balls the same?
Yes. Teflon™ is a brand name for PTFE. We manufacture Teflon-equivalent solid PTFE balls and virgin PTFE balls with identical polymer chemistry.
What engineering plastic balls do you manufacture besides PTFE?
Delrin (POM), polypropylene, nylon, UHMWPE, and PEEK spheres. Browse engineering plastic balls.
How many years of PTFE ball manufacturing experience do you have?
Hemsun Engg. Industries has 35+ years of in-house manufacturing experience since 1990. We are a direct manufacturer — not a trader.
Can you manufacture custom size PTFE balls?
Yes. We machine custom diameters from drawings, samples, or specifications across our full 5 mm to 310 mm range.
What temperature range can PTFE balls withstand?
Virgin PTFE balls typically operate from -200°C to +260°C continuous service.
Do you accept engineering drawings for OEM PTFE balls?
Yes. Drawings in metric or inch with diameter, tolerance, material, and finish notes are preferred for OEM programs.
What manufacturing process do you use for solid PTFE balls?
Compression molding, controlled sintering, ball machining, finishing, inspection, and dispatch — all in-house. Read the full process guide.
What are PTFE pump balls?
Check valve spheres inside AODD pumps, dosing pumps, and reciprocating chemical transfer pumps. Details on our PTFE pump balls page.
Do you manufacture hollow PTFE balls?
Yes. PTFE hollow balls are built from two virgin PTFE hemispheres joined at the equator by thermal fusion and chemical welding — suited to floats, rotameters, and lightweight buoyancy assemblies.
Do you export PTFE balls internationally?
Yes. We ship worldwide with export documentation, MTC, and ISPM-15 packaging. See OEM export supply.
