Thread cold forming machine SJ-42

shrinkage machine product characteristics: This machine belongs to non-cutting processing equipment. It uses hydraulic technology to send the shrinkage parts such as round steel and thread steel into special dies for cold compression forming. The density of shrinkage parts can be greatly increased, thereby improving the tensile strength of materials. The defect of reducing tensile force and impact toughness due to window peeling is solved. With the characteristics of fast processing speed and accurate size, it is an ideal equipment for processing Mine bolts and ground angle bolts.
