The aluminium forging cycle aims at eliminating graphitised oils, which, besides creating an unpleasant workplace, tend to lower the temperature of the dies. The DRY LUB SYSTEM has partly solved these problems, improving the quality of the forged piece.
A hot-melt dry lubricant is applied at every production cycle. This operation ensures good lubrication and does not reduce the temperature of the dies, thus improving the smoothness of the material. This system was developed eight years ago for the “COBAPRES” cycle, and today is used also for forging aluminium.
How the DRY LUB SYSTEM works
The Dry Lub System is an Altea patented product. It took us a lot of time and hard work to develop and test this system, during which other high-performing equipment and products were created. A hot-melt dry lubricant is applied at every production cycle. This operation ensures good lubrication and does not reduce the temperature of the dies. When it comes into contact with the hot mould, the product distributed electrostatically melts, expanding to the deepest points. This way, it creates a highly efficient release film, without leaving the moulds dirty.
