Manufacturing method of hot-stamped product

Abstract

The present invention relates to a manufacturing method of a hot-stamped product, manufacturing the product (including parts) from a steel sheet through a hot stamping (hot-press) process, and it is possible to inhibit or prevent an adhesion (agglutination) of aluminum plating to a hot-stamping mold when manufacturing the product from the aluminum plating steel sheet in particular.

What is claimed is: 
     
         1 . A manufacturing method of a hot-stamped product, for making from aluminum plating steel sheet to a product by a hot-stamping process, comprising steps of:
 preparing water-soluble agent having no flammability and non-volatility, where a mixing ratio of macromolecular polymer is 1 to 25 part by weight (weight %), a mixing ratio of water is 50 to 98 part by weight (weight %) and a mixing ratio of surfactant is 1 to 25 part by weight (weight %);   applying said water-soluble agent to a surface of a mold opposite to said aluminum plating steel sheet; and   manufacturing said product after application of said water-soluble agent,   thereby to apply said water-soluble agent to said surface of said mold so as to inhibit or prevent adhesion of aluminum plating.   
     
     
         2 . The method according to  claim 1 , wherein said application of said water-soluble agent is regularly performed.
