VDI 27 surface finish is in the lighter texture range for the VDI 3400 surface finish standard. It is widely used for automotive parts, consumer electronics, and other products where a specific texture is desired for aesthetic or functional reasons. The VDI 27 provides enough roughness for hand gripping and beautiful finish look.

VDI 3400 is a vital texture standard developed by the Society of German Engineers (Verein Deutscher Ingenieure) that defines surface finishes for mold-making. This comprehensive standard covers 45 distinct texture grades, ranging from smooth to rough finishes, catering to various industries and applications.

VDI 3400 refers to the texturing standard set by the German Engineers Association Verein Deutscher Ingenieure (VDI). It is mainly processed by electrospark machining (EDM) in mold processing, but it can also be done by traditional texturing methods such as chemical etching.

The VDI 3400 surface finish is mainly processed by Electrical Discharge Machining (EDM) when mold machining. It could also be done by the traditional texturing method. The complete VDI 3400 texture covers 45 values, but the most common use values are: VDI 12, VDI 15, VDI 18, VDI 21, VDI 24, VDI 27. VDI 30, VDI 33, VDI 36, VDI 39, VDI 42, VD I45.
