消化塑料制件图,了解制件的用途
消化塑料制件图,了解制件的用途,分析塑料制件的工艺性,尺寸精度等技术要求。
Digest the drawing of plastic parts, understand the purpose of parts,
and analyze the technical requirements of plastic parts, such as
manufacturability, dimensional accuracy and so on.
例如塑料制件在外表形状、颜色透明度、使用性能方面的要求是什么,塑件的几何结构、斜度、嵌件等情况是否合理,熔接痕、缩孔等成型缺陷的允许程度,有无涂装、电镀、胶接、钻孔等后加工。选择塑料制件尺寸精度的尺寸进行分析,看看估计成型公差是否低于塑料制件的公差,能否成型出合乎要求的塑料制件来。此外,还要了解塑料的塑化及成型工艺参数。
For example, what are the requirements of plastic parts in terms of
appearance shape, color transparency and service performance, whether
the geometric structure, slope, insert and other conditions of plastic
parts are reasonable, the allowable degree of forming defects such as
fusion marks and shrinkage holes, and whether there is post-processing
such as coating, electroplating, bonding and drilling. Select the size
of plastic parts for dimensional accuracy analysis to see whether the
estimated forming tolerance is lower than the tolerance of plastic parts
and whether plastic parts can be formed to meet the requirements. In
addition, we should also understand the plasticization and molding
process parameters of plastics
