COMEXALE has developed a global offer of lubrificants for Aluminium Extrusion Industry.

The starting material for extrusion is a cylindrical aluminum billet. Individual sections of these blocks are heated to 450 °C and forced by a stem through to stick at these temperatures. It is therefore necessary to apply a release agent or lubricant between the dummy block and the aluminum billet.

Conventional release agents, such as oils, greases and carbon black contaminate the product and are difficult to use. Hexagonal boron nitride offers excellent properties as release agent and lubricant and is easy to apply (EKamold® P2 boron nitride powder, EKamold® WP suspensions and EKamold® Extrusion Spray)
