The external lubrication of the billet for the extrusion of brass billets has been achieved successfully.
The study started from the need to increase the life of the container and to facilitate the cleaning operation of the internal surface of the container.
After six months of work and some unpleasant initial imperfections, often caused by a machine downtime, which also have also been eliminated, the results have been achieved with satisfaction.
The application of the dry powder lubricant is performed electrostatically by using a very low amount of product (about 6/8 g for a 2000 mm billet with a 300 mm)
The lubrication head, specially designed according to the customer’s needs, is placed between the loader that carries the hot billet (800° C) and the loading system designed to position the billet in the container.
