With more than 40 years of experience in the extrusion of plastic and high-temperature resistant materials, Primac technology in the manufacturing equipment and production lines for PTFE pipes. PTFE pipes are used for special applications: in the medical industry (i.e. to convey food fluids, etc.), and in the electronic and automotive industries. Baruffaldi-Primac know-how guarantees top quality standards of the final product, which makes it possible to obtain the certifications the market requires.

Our equipment for PTFE includes the following technologies:

Dreno Covering TNT/50-200 operates in the corrugated pipe extrusion process, it is a machine for covering corrugated drainage pipes with PP (Geotextile), TNT disposable fabric for 50 mm pipe diameter up to 200 mm.

The Dreno Covering TNT/50-200 machine is equipped with haul-offs which pull the pipe at the same speed as the pipe extrusion line. The pipe is covered in material in a continuous mode. The welding is also continuous and is performed by an ultrasonic welding head. Electronic controls adjust power according to the type of material and the welding speed.

The Dreno Covering TNT/50-200 machine is equipped with two coils. The first one feeds the fabric onto the pipe, the second one is only activated when the fabric on the first one runs out. This means the machine never has to stop to change over a coil. All machine functions can be set from the touch screen panel. System control is managed by a PLC and other electronic equipment (diameter changeovers between Ø 50 mm and Ø 200 mm do not require any additional tooling). The Dreno Covering TNT/50-200 is eligible to work on-line and off-line, on the flexible tube and on the rigid tube.

Automatic in-line machinery for the socket welding process of PE and PP corrugated pipes of between 110 and 1400 mm diameter.
