1. 铝挤压的润滑剂和离型剂从前,为改善铝挤压性能,一直沿用着润滑剂.如进行适宜的润滑,是能同时减少模子的传热和磨损的,但是,与此相反,如润滑剂使用不当,便可能造成挤压加工时出现与模子相关的故障.这种现象常常出现在型材周长比挤压筒周长大得多和型材壁厚不均匀的情况下.铝型材挤压时,在使用实心模和平面模等稳定形式场合,每次挤压终了剪切残料之后都要在模子工作面上涂上润滑剂,以防止模子磨损.
1. Aluminum Extruded Lubricants and Release Agents Traditionally, lubricants have been used to improve the aluminum extrusion performance, as appropriate lubrication can reduce both the heat transfer and the wear of the mold, but in contrast , Such as improper use of lubricants may cause mold-related problems during extrusion processing.This phenomenon often occurs when the profile circumference is much longer than the circumference of the extrusion cylinder and the profile wall thickness is not uniform Aluminum Profile extrusion, the use of solid mode and flat mode and other stable forms of occasions, after each squeeze the end of the shear material after the mold surface must be coated with lubricant to prevent mold wear.
