Complete line for non sintered P.T.F.E. tape

1. Sifter machine

The machine is used to properly mix powder and additives, in order to obtain, after a certain period, a perfectly mixed with a pastry consistency product, ready for the next steps. During processing the container oscillates vertically in order to mix the components in the best possible way.

2. Oven for stabilisation

After the previous process, this machine stabilises PTFE molecules in order to optimize the characteristics of the material, making it suitable for subsequent processing.

3. Preform making machine

This machine compacts powder and additives blend; in this way the result is a cylinder corresponding to the desired size, suitable to be transformed during the next extrusion processes.

4. Vertical/horizontal extruder

The machine extrudes the product obtained from the preform making machine and in that way it gives to the product the desired shape according to spinneret. A vertical or horizontal arrangement of the machine can be chosen according to the overall dimensions.

5. Calendering machine

The machine laminates the product obtained by extrusion, if it is necessary to obtain a film of desired thickness. The machine is electronically controlled in C.A. with vector inverters.

6. Drying oven

The machine removes additives and oils from the product (they can be recycled). It can work individually with speed control, or in line with a calender machine (with torque control). The heating technology is obtained through the use of the "infrared" system.

7. Straightening oven

The product obtained needs further heat treatment, before going on to the following phases. This treatment is aimed at stabilizing its final properties, also allowing a reduction in thickness. The product obtained can be 12 times longer than it was at the beginning. The ironing control is electronic and the heating technology is "infrared". This machine is also used to obtain tapes and monoaxial E-PTFE (expanded PTFE).

8.1. Manual cutting machine F260/280

This is the latest machine on the production line. The manual cutter unwinds the tape that has been previously wound on the reel; the tape, through the use of special blades, will be cut into strips of the desired width and then they are wound onto rolls. Once the meter is reached, an empty carrier substitutes the ones full of rolls, so that the operator can continue in unloading and loading operations without stopping production.

8.2. Automatic cutter

The machine performs the same operations described in the previous point in an automatic way: cutting, wrapping and packaging
