Title:
METHOD FOR MANUFACTURING A METAL SCRAP COMPRESSION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/099320
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a metal scrap compression material. According to the method for manufacturing the metal scrap compression material, a through-hole is not punched after compressing the metal scrap compression material, but rather a through-hole is formed during the process of manufacturing the metal scrap compression material. Thus, even though the through-hole is formed in the metal scrap compression material which is compressed and formed so as to be highly dense, friction and stress applied to a core may be minimized to minimize the damage of the core and a failure occurrence rate.
