  • Plunger lubricant for die casting and method of applying the same
    Patent number: 11566201
    Abstract: A plunger lubricant for die casting includes a component (a), a component (b), a component (c), and water. The component (a) is one or two or more compounds selected from among mineral oils, synthetic hydrocarbons, and fatty acid esters. The component (b) is one or two or more compounds selected from among alkali metal salts of higher fatty acids or alkali metal salts of aliphatic hydroxy acids. The component (c) is an alkali metal salt of an oxoacid or polyoxoacid that is able to be dehydrated and condensed.

  • DI FORMING WATER-BASED COOLANT OF LAMINATED METAL SHEET AND METHOD OF DI FORMING LAMINATED METAL SHEET
    Publication number: 20150107326
    Abstract: A method of DI forming a laminated metal sheet includes drawing a laminated metal sheet; and redrawing and ironing the drawn laminated metal sheet, wherein a water-based coolant including (a) at least one base selected from the group consisting of alkanolamines and alkali metal hydroxides, (b) a fatty acid, and (c) water is used in the redrawing and ironing, and wherein a total content of the base (a) and the fatty acid (b) is 0.02 to 4% by mass and a ratio of a straight-chain fatty acid having a carbon number of 6 to 12 in the fatty acid (b) is 80 to 100% by mass.
