New lubricants help metalformers improve quality and tool life while taking on more challenging materials, and at the same time control costs by, among other advantages, eliminating cleaning operations. The upwardly spiraling cost of oil has stampers looking for alternative lubricant types. Demanding high-tonnage transfer applications as well as high-speed progressive-die applications require robust lubes. And, the well-publicized move toward new advanced high-strength steels (AHSS) by the automotive industry has stampers scratching their heads as the high temperatures generated when forming these steels breaks down tool coatings and, ultimately, the tooling prematurely. Demand for lubricants that exhibit the characteristics of a vanishing lubricant yet are water soluble has steadily increased in the marketplace. Conventional synthetics also fail to meet the needs of elevated-temperature applications such as when stamping AHSS. In general customers have been looking to move more toward water-dilutable products due to dramatically rising and unpredictable oil costs. A new series of lubricants from Etna Products Inc., Masterdraw SSY, promises to offer corrosion protection in addition to dependable lubricity. The semi-synthetic fluids, in three compositions, offer the advantages of a soluble oil and a synthetic fluid. A new dry-film lubricant introduced earlier this year by GYG U.S.A., Inc., called Proform, reportedly optimizes lubricity and rust prevention. Stampers performing medium- to heavy-duty drawing as well as stamping and looking for a drawing compound that leaves no residue can try the new Drawsol WM 990 water-soluble lube from D.A. Stuart Co. High-temperature drawing, particularly of tough stainless-steel alloys, recently received the attention of Tower Oil, with its introduction of Towerdraw 9890-TD. A petroleum-based product, it's formulated to offer good wetting, anti-galling characteristics and low odor at high temperatures (it includes sulfurchlorinated extreme-pressure additives). Another high-heat drawing compound recently introduced to the market comes from Houghton Intl.: Houghto-DrawV-2000, a vegetable-oilbased product with high emulsion stability without chlorine, phosphorous or sulphur additives.
