2023年9月12日 · VDI 3400 Surface Finish (commonly known as VDI surface finish) refers to the mold texture standard set by Verein Deutscher Ingenieure (VDI), the Society of German Engineers. The VDI 3400 surface finish is mainly processed by Electrical Discharge Machining (EDM) when mold machining.

2022年12月16日 · VDI 3400 表面处理标准主要适用于采用放电加工 （EDM）工艺的零部件，某些传统的表面处理工艺（与SPI 一样）同样适用于 VDI 标准。 尽管这套标准是由德国工程协会制订的，全球多个地区如北美、欧洲和亚洲的制造商们也广泛采用VDI 标准。 VDI 标准使用不同的参数代表零部件的表面光洁度。 从上面的动图里，你可以看到不同的VDI 参数对应的表面处理效果。 这两套注塑成型的表面处理工艺标准内，SPI A级和 B级是表面最光滑的，表面粗糙度最低，价 …

VDI 3400 Surface Finish（俗称VDI表面光洁度）是指由德国工程师协会Verein Deutscher Ingenieure（VDI）制定的模具纹理标准。 VDI 3400 表面光洁度在模具加工时主要采用电火花加工 (EDM) 加工。

The VDI 3400 refers to the German mold texture standard set by VDI (Verein Deutscher Ingenieure), the Society of German Engineers. The standard covers 45 grades of textures : from VDI 3400 #0 to #45 (RA 0.10 μm to RA 18.00 μm).

The VDI 21 surface finish is achieved through a specific manufacturing process. This involves using specialized tools and machinery to create the desired texture on the surface of the material. It could be done both via EDM or chemical engraving texturing.

2021年12月27日 · VDI surface finish refers to the Society of German Engineers’ mould texture standard and is widely utilised by tool producers worldwide, including North America, Europe, and Asia. The VDI 3400 surface finish is mainly treated using Electrical Discharge Machining (EDM) when mould machining.
