Abstract
The present invention resides in a die casting process using a solid lubricant composition. The lubricant composition preferably comprises (a) about 30% to about 70% by weight of a high melting point synthetic wax having a melting point in the range of about 270.degree. F. to about 310.degree. F. (132.degree.-154.degree. C.); (b) about 10 to about 50% by weight of a wax having a lower melting point in the range of about 150.degree. F. to about 250.degree. F. (65.degree.-121.degree. C.).
