“毛刺”及“震痕”产生的原因及解决思路

Causes of “Burs”and “Vibration Marks” and Solution Concept

论述了模具、铸棒、挤压工艺3个因素影响"毛刺"和"震痕"的产生及解决方法.在生产高端产品的过程中,需要各工序、各操作人员的紧密配合,总接经验,不断提高操作水平,才能达到提高成品质量、降低成本的目的.

Three factors, that is mold, cast bar, and extrusion process, which cause the ＂burs＂ and ＂vibration marks＂, and the solution, are described. The production of high-end products needs close cooperation of each process and staff during the production. The experience shall be summarized so as to keep on improving the operation level, increase the finished product quality and lower the cost.
