Lubrication Technology for Metal Formers
encountered, to ensure optimal friction behavior, including heat resistance, lubricity and cleanability—from room temperature through 150 to 250 C.
“Further, these formulations must be compatible with joining and bond- ing methods,” Schaeffler adds, “and must be removable prior to e-coat. The need for aluminum and advanced high strength steels in vehicle structures will only grow, and the lubricant char-
acteristics must keep pace with these changes. During my conference kickoff presentation, I’ll focus on the oppor- tunities and challenges associated with these new options in body construction and the role that sheet metal lubrica- tion can play.”
Following on the Theme
...of the role that lubricants play in automotive lightweighting, Paul Bosler,
product manager, OEM metalforming lubricants and corrosion preventatives, at Fuchs Lubricants, will address lubri- cation strategies for cold, warm and hot forming of aluminum alloys.
“The use of aluminum to form vehi- cle body panels, components and even structural parts,” says Bosler, building on Schaeffler’s theme, “has become important to the strategies of automo- tive OEMs to improve gas mileage and passenger safety. As well, the use of aluminum has become particularly important to the future of e-mobility, to lightweight vehicles and to form unique components, such as battery trays. My presentation will review the properties and characteristics of alu- minum alloys compared to steels, and how these differences can affect the performance and requirements of lubricants used in traditional metal forming processes, such as cold stamp- ing and blank washing.”
Bosler also will review new lubricant technologies and use strategies designed to improve performance of aluminum—in the press and in auto- motive post-processes.
“Finally,” Bosler adds, “I will present new lubricants designed for warm and hot forming of aluminum sheet metal. During these processes, high-strength aluminum-alloy blanks are heated and formed in a press at temperatures from 1000 to 5000 C. Sound lubrication selec- tion and use is essential to successful forming using these developing process- es. I’ll provide a history of lubricant development for these processes, and also share some related case studies.”
When it comes to delivering lubri- cant to the presses in a productive and cost-effective way, often a centralized delivery system proves optimal, and that’s the subject of another day-one presentation. Subtitled, The Heart and Flow of the Press Room, the presenta- tion, by Troy Turnbull, president of Industrial Innovations, stresses that “to ensure lubrication, often stampers will over-apply lubricant, resulting in significant waste and potentially dan- gerous environments.”
