Abstract A die-casting arrangement which prevents a lubricant from becoming mixed into a die cast article which might cause it to bulge when later heated. The lubricating agent is sprayed over a high-temperature portion of a sprue interconnecting a mold cavity and an injection sleeve in order to partly carbonize the lubricant. The carbonized lubricating agent even if mixed into a die cast article will not expand even when the article is heated thereby preventing bulging of the article.
