挤压铝型材表面毛刺形成原因及预防方法

在铝型材的挤压生产中，常见的缺陷是比较直观的：如弯曲、扭拧、磕碰、夹渣等。而表面吸附毛刺缺陷，不仔细观察或手摸较难发现，但它严重影响后续氧化、电泳等型材的表面质量，很难去除掉，严重影响装饰型材的表面。因此，要在挤压生产实践中不断地观察分析，总结其成因，及时采取措施，以减少或杜绝这种缺陷的出现。

Extruded Aluminum Surface Burr Causes and Prevention

Aluminum extrusion,the common defect is relatively straightforward：such as bend,twist,bump,slag,etc.The surface adsorption burr defects,not carefully observed or hands touch more difficult to find,but it seriously affected the subsequent oxidation, electrophoresis profiles of surface quality, difficult to remove,seriously affecting the decorative profile of the surface.Therefore,in extrusion practice,continue to observe and analyze,summarize its causes,to take timely measures to reduce or eliminate the appearance of this defect.
