EKamold® BORON NITRIDE POWDERS, SUSPENSIONS AND SPRAYS AS RELEASE AGENTS AND LUBRICANTS FOR ALUMINUM EXTRUSION
Extrusion of aluminum profiles combines design variation with high production output and is therefore the most economic shaping process. Since the aluminum alloys for extrusion need to be heated to at least 450 °C and must bond at this temperature, it is vital that a release agent or lubricant be applied between the aluminum billet and dummy block.
EKamold® Boron Nitride Powders as Release Agents and Lubricants
EKamold® has proved to be the optimum solution since it can be applied electrostatically, i.e. dry and without auxiliaries, to the dummy block and/or the end face. EKamold® P2 also offers other advantages:
- Outstanding release and lubricating properties
- Increased safety and cleanliness in the pressing area since there is no naked gas flame present
- Economical powder consumption
- Reduced coating frequency results in fewer downtimes
- Increased productivity
- Optimized product quality
- No physiological concerns
EKamold® Boron Nitride Sprays as Release Agents and Lubricants
The boron nitride sprays Ekamold® TG and EKamold® Extrusion are ideal for protecting the inner surfaces of the shaping molds. They offer the following advantages:
- Outstanding corrosion protection
- Rapid drying without the need for heat treatment
- Outstanding release and lubricating properties
EKamold® Boron Nitride Suspensions as Release Agents and Lubricants
EKamold® WP is recommended for coating the shear blade because of the following characteristics:
- Simple spray application
- Outstanding release and lubricating properties
- Neat cut surfaces reduce the risk of entrapped air
