Warm Extrusion Lubrication for Precision Forming
Warm extrusion occupies the challenging intermediate temperature range where traditional cold-forming oils vaporize and hot-forging graphites fail to adhere. Our synthetic wax technology bridges this gap, providing impeccable flow kinetics and die protection.
Mastering the Intermediate Thermal Zone
Operating typically between 300°C and 800°C depending on the alloy, warm extrusion requires a delicate balance of lubricity and cooling. The semi-solid state of the workpiece demands a lubricant that can withstand the increasing deformation resistance while facilitating smooth material flow.
Inadequate boundary lubrication in this regime leads to severe frictional spikes, causing die wear, dimension inaccuracies, and surface defects on the extruded profiles. The absence of a stable tribo-film directly impacts the metallurgical structure of the near-net-shape components.
Phase-Optimized Boundary Layers
Our approach utilizes residue-free lubricants for extrusion processes engineered specifically for warm working temperatures. The carefully calibrated phase transitions allow our waxes to melt instantly upon contact with the billet, forming a highly tenacious, load-bearing film precisely when deformation forces peak.
This dynamic viscosity control ensures optimal hydrostatic pressure distribution within the die cavity. As a result, engineers observe a significant reduction in forming forces, improved material plasticity, and extended tool lifecycles without the clean-up issues associated with solid suspensions.
