Fin Tube Machine — PTF 40, 70 & 100
Our fin tube machines produce spirally crimped finned tubes: the fin strip is wound in a continuous spiral around the base tube under tension, and the machine crimps it to form interlocking ridges for a secure mechanical bond without welding. This process delivers high heat transfer, consistent fin quality, and durable attachment under thermal cycling and vibration. PLC-controlled operation allows adjustable fin height and spacing at production speeds up to 25 m/min for use in heat exchangers, boilers, radiators, and cooling systems.
Spirally Crimped Process
- Winding & crimping: Fin strip is fed and wound around the base tube at a precise angle; crimping creates interlocking ridges between fin and tube for a strong mechanical bond
- PLC control: Adjustable fin height, pitch, and spacing for consistent quality and customizable thermal performance

Frequently Asked Questions
What tube sizes can the fin tube machine process?
Base tubes from 12 to 50 mm diameter with fin heights of 5 to 20 mm, at production speeds up to 25 m/min.
What is the difference between the PTF 40, 70, and 100 models?
The models cover increasing tube-size and output ranges; all are PLC-controlled with a digital interface and 15-30 kW drives. Tell us your tube spec and volumes and we will recommend the right model.
Is the fin tube machine customised to my requirement?
Yes. Every machine we build is custom-engineered — capacity, dimensions, and configuration are matched to your line. Send your requirement via the enquiry form or call +91 91091 02280 for a firm quote.
*This is only an approximate starting price — a rough, loose estimate. Every machine is custom-engineered to your requirements, so the final price depends on capacity, specifications, and configuration — reach out for a firm quote.
