Abstract：

Warm extrusion has the advantages of the cold extrusion and hot extrusion,and avoids their defects. The key technology of warm extrusion is the lubrication measure. Good lubricants can improve plastic forming ability of metal materials and mold life.The performance requirements of warm extrusion lubricant was analyzed to sum up the lubricants used in different extrusion temperatures and different materials, and several practical warm extrusion lubricants were introduced.The cooling method for warm extrusion die was developed.
