CNC Machined | Compression Molded | Reverse Engineered | All PTFE Grades
HEMSUN ENGG. INDUSTRIES is a trusted Custom PTFE Parts manufacturer, supplier, and exporter from Ahmedabad, India. We manufacture precision Custom PTFE Components — also known as Custom Teflon Parts or Custom Polytetrafluoroethylene Components — by CNC turning and milling on our in-house VMC and 5 CNC lathes, and by compression molding for larger or near-net-shape parts. We accept customer design input in any format — CAD/CAM files, 2D drawings, PDF specifications, or physical samples for reverse engineering — and manufacture from single prototypes to bulk production volumes in all PTFE grades. Exported to UAE, Germany, USA, Japan, Singapore, Brazil, Turkey, and the Middle East.

Manufacturing Process
Custom PTFE Parts: Step 1 — customer provides drawing, CAD file, or sample. Step 2 — HEMSUN engineering reviews and recommends optimal PTFE grade. Step 3 — parts are CNC machined (lathe/VMC) or compression molded. Step 4 — dimensional inspection against drawings. Step 5 — export-grade packaging and despatch. Tolerances typically ±0.05mm to ±0.1mm achievable depending on geometry and size.
Compliance & Standards
IEC registered. Food Grade PTFE parts FDA 21 CFR compliant. Material certificates, dimensional inspection reports, and export documentation provided. Regular export to UAE, Germany, USA, Japan, Singapore, Brazil, Turkey, Saudi Arabia, Qatar, and Middle East.
Frequently Asked Questions
What file formats do you accept for custom PTFE part drawings?
We accept STEP (.stp), IGES (.igs), DXF (.dxf), DWG (.dwg), SolidWorks (.sldprt), PDF drawings, and hand-sketched drawings with dimensions. We can also manufacture from a physical sample without any drawing through our reverse engineering service.
Can you reverse engineer a PTFE part from a physical sample?
Yes. Send us the physical sample — a worn component, broken part, or reference piece — and our engineering team will measure, draw, and reproduce it in the appropriate PTFE grade. This is particularly useful for replacing obsolete OEM PTFE parts for pumps, valves, and compressors.
What tolerances can you achieve in custom PTFE machining?
We typically achieve ±0.05mm to ±0.1mm depending on part geometry and size. PTFE is machinable to tight tolerances on our in-house VMC and 5 CNC lathes. Share your drawing and we will confirm achievable tolerances for your specific part geometry.
What is the minimum order quantity for custom PTFE parts?
We manufacture from single prototype pieces to bulk production quantities. MOQ is flexible depending on material and complexity. Contact us with your requirement and drawing for a quote within one business day.
