Quick Answer: What to Include in a PTFE Ball RFQ
Send diameter, tolerance, quantity, application media and temperature, and shipping destination. Attach a drawing (PDF, STEP, DXF) or physical sample for custom work. This is everything our sales team needs to return accurate factory pricing without back-and-forth.
RFQ Checklist for Engineers and Procurement
| Field | Why It Matters | Example |
|---|---|---|
| Nominal diameter | Determines die selection and machining path | 25.40 mm (1.000″) |
| Tolerance band | Affects grinding time and inspection method | ±0.10 mm or ±0.01 mm (tight OEM) |
| Grade / resin | Virgin, coloured, or filled compound | Virgin PTFE (GFL Inoflon equivalent) |
| Application | Guides grade and surface finish recommendation | Chemical check valve, sulfuric acid, 80°C |
| Quantity | MOQ and tooling amortization | 500 pcs / month OEM program |
| Destination | Shipping terms and packaging | FOB Mundra or DAP warehouse |
Drawing and Sample Submissions
For custom PTFE balls, we accept PDF, DXF, DWG, STEP, STP, IGES, and SolidWorks files. Physical samples can be shipped to our Dahegam facility for reverse measurement. Drawings should note:
-
Nominal diameter and tolerance (metric or inch)
-
Material grade (virgin, filled type, colour if applicable)
-
Surface finish or sphericity requirement
-
Special features: holes, threads, flats, grooves
-
Regulatory needs: FDA, MTC, inspection report
What Direct Factory Sourcing Looks Like
Buying from our Gujarat plant (see factory capabilities) means:
-
No broker markup — pricing reflects in-house production cost
-
Batch traceability — resin lot, compaction run, and inspection records
-
Technical access — direct communication with production and QA teams
-
Flexible runs — prototype quantities through volume OEM batches
Lead Times and Packaging Expectations
| Order Type | Typical Dispatch |
|---|---|
| Standard virgin stock sizes | 24–48 hours |
| Coloured or filled custom | 7–15 business days |
| Export OEM volume | Agreed per contract; see export guide (/ptfe-ball-oem-supplier-and-exporter-in-india) |
Domestic orders ship in anti-static polybags and corrugated cartons. Export programs use multi-layer packaging with ISPM-15 pallets for sea freight.
