SJ-65 shrinkage machine 友民product characteristics: This 身視machine belongs to鄉分 non-cutting processing equipment我明. It uses hydraulic techn家服ology to send the shrinkage parts s笑女uch as round steel and thread steel i現土nto special dies for cold compre信小ssion forming. The density of shrinkage票短 parts can be greatly incr雨現eased, thereby improving the ten聽鐘sile strength of materials. The defe空山ct of reducing tensile force and im微工pact toughness due to 們秒window peeling is solved. With the cha照就racteristics of fast processin船雪g speed and accurate size民子, it is an ideal 紅吃equipment for processing M金船ine bolts and ground a靜城ngle bolts.
