摘要
The present invention relates to a casting mold surface treatment method, and a casting mold having a carbon film formed on its surface by this surface treatment method. In the casting process, a die lubricant is generally applied to a molding surface of the casting mold, by which the product is released more easily when the molded product is to be removed from the casting mold. However, when casting is repeated, the material may stick to the casting mold, and removing the product from the casting mold becomes more difficult. This problem can be resolved by covering the surface of the casting mold with a carbon film. The carbon film prevents the molten metal and the base material of the casting mold from making direct contact, suppressing the sticking of molten metal to the casting mold and an increase in release resistance.
