  • Switchboard

Station 1 – CONE GRINDING

The actuator picks one die from the storage unit and insert it in rotating pliers; the machine automatically sets the contact point and then starts grinding the die.

The control of die diameter is made by adjustable steps to get the highest precision level.

Station 2 - CONE FINISHING

The actuator picks the die which has been previously grinded, put it in the second station and automatically fasten it by rotating pliers. A small quantity of diamond paste is automatically applied, then the machine sets the contact point and starts the process.

The control of die diameter is made by adjustable steps to get the highest precision level.

Station 3 - CYLINDER CALIBRATION

The actuator picks the die from the Cone Finishing station and delivers it to the rotating pliers of the Cylinder Calibration. A small quantity of diamond paste is applied, then the machine sets the contact point and starts the process by vibration and position control.

Station 4 - DIE STAMPING

Bright Soaped / Bright Clean Wire

07.04.2014

Wire rod is drawn by straight-line dry drawing machines, from diam. 1,50 mm to 8 mm, for the production of bright soaped wire or bright clean wire.

When diameters are thinner, wire is drawn by wet drawing process, until diam. 0,40 mm, using anti-skidding wet drawing machines.

Product range: from diam. 1,50 mm to 8 mm.

Finishing: soaped, bright clean, for chrome plating.

Galvanized Wire

07.04.2014

Our galvanized wire production is made by a new 30 wires galvanizing line, working with wires from 0,50 mm to 6,50 mm. Our latest technology galvanizing plant can manufacture galvanized wire with ordinary zinc quantity or heavy zinc quantity through a gas wipe system. The line production capacity makes Tecnofil reach a monthly output of 3,500 tons of galvanized wire.

In the galvanizing department, a quality control unit is constantly supervising the correct zinc coating of wires. The final part of our line is equipped with static spoolers(coilers) and dynamic spoolers.

Soft galvanized wire

The wire is hot-dip galvanized and then annealed in in-line furnaces. This treatment reduces the tensile strength and increases the elongation range.

Hard Galvanized Wire

The wire is hot-dip galvanized with no annealing process. This treatment keeps the drawn wires mechanical features unchanged.

Re-drawn Galvanized Wire

The wire is drawn once again to get a particularly bright and polished surface.

Product range: from diam. 0,50 mm to 6,50 mm.

Finishing: ordinary galvanized – heavy galvanized – zinc quantity depending on customer needs according to UNI EN 10244-2.
