Purpose : The machine developed is for manufacture of finned tubes. The machine is basically capable of manufacturing various kinds of finned tubes like Embedded fins (G-fins), wrap around (L and LL fins), knurled, soldered fins, etc.

Main Purpose of the machine is the process of Continuous finning.Where in there is no limitation of the length of tube being finned. Also it is suitable for continuous production where in tubes can be fed in continuously one after the other.

The machine is capable of making Helical continuous fins with various pitches. For this the fin material is purposefully thinned out using a Pan wheel at the periphery so that the fin curls around the tube in the required manner.

It can handle various tubes materials like Brass, Copper, Steel, Stainless Steel and fin materials like Copper, aluminium,cupro-nickel etc.

The machine is suitable for fast setting change from one type of tube to another.

• The machine will have rigid fabricated structure, properly stress relieved before machining
• A well-designed Fin guide mechanism is provided which will guide the fin from the bobbin on to the Pan wheel. It is also provided with a felt cleaning with pneumatic pressure. Also guide mechanism will form the required L and LL in L finning.
• We will be providing complete set of tooling as per requirement of the customer.The tools are specially designed to meet the finning requirements. The tool material are carefully selected and they undergo a proper heat treatment process to ensure long life.
