Lube Additives for Metal Forming Lubricants
Overview:
Drawing, stamping, rolling, and forging impose extreme pressures and sliding. Boundary-lubrication additives are essential to prevent scoring and achieve target draw ratios.
Why an additive package is required:
- Provide EP/antiwear films that survive extreme pressure and temperature spikes.
- Reduce friction to enable deeper draws and minimize die wear and galling.
- Offer corrosion protection between stages and ease post-process cleaning.
Typical additive families employed:
Sulfurized/phosphorus EP agents, polymeric/ester lubricity improvers, solid lubricants where applicable, corrosion inhibitors, emulsifiers for water-dilutable systems.
Indicative performance tests:
Cup drawing/limiting draw ratio, 4-ball EP/wear (ASTM D2783/D4172), Falex (ASTM D3233), staining/corrosion per substrate, residue/cleanability evaluations.
