Lubrication concepts in cold-forging applications differ from those of hot forging. Cold-forming lubrication relies on traditional, complicated phosphate and soap treatments. Newer polymer coatings can replace this complex process, significantly reducing the waste stream and improving lubrication performance.
In the hot and warm forging of steel, there is a clear trend to replace graphite-based die lubricants with synthetic lubricants. This is driven by the need for cleaner work environments, easier handling and to avoid graphite-induced galvanic corrosion of equipment.
