Abstract
Lubricant compositions and methods of producing die-cast products by applying such a lubricant composition to a working surface of a die prior to casting a product from a molten metal injected into the die. The composition serves as lubricant between the die and resulting product, and contains at least one active component that reacts with an oxide of the metal to remove a layer of the oxide that forms on a surface of the melt during the die casting process.
Claims14
A lubricant composition for coating working surfaces of a die that are contacted with a melt containing a molten metal during a die casting process, the lubricant composition comprising:
- a carrier fluid;
- and
- at least one active component that reacts with an oxide of the metal to remove a layer of the oxide that forms on a surface of the melt, wherein
- the carrier fluid is a die lubricant;
- and
- the at least one active component is a complex salt comprising one or more of K2TiF6 and KBF4.
