摘要
采用空心挤压垫即挤压管材用的挤压垫和穿孔针复合使用的新工艺,解决了在只配备锯的管材挤压机上挤压棒材时压余难以分离的问题。
A new extrusion process using a hollow dummy bar together with a piercing mandrel can remove the difficulties in separating the discard when bars are manufactured on a tube making extruder only equipped with a saw for separating the discard.
