VDI 3400 is also called “VDI 3400 texture” or “VDI surface treatment”. The standard covers a total of 45 levels of texture: From VDI 3400 #0 to #45 (RA 0.10 μm to RA 18.00 μm). However, the most commonly used textures are the following 12 values: VDI 12, VDI 15, VDI 18, VDI 21, VDI 24, VDI 27. VDI 30, VDI 33, VDI 36, VDI 39, VDI 42 ...

Using the sandblasting machine to sandblast on mold cavity surface with proration of glass sand to achieve VDI texture. Making the surface have average roughness with 3 kinds of glossness of matt, semi-gloss and gloss. VDI 3400 Ref.12/ 15/ 18/ 21/ 24/ 27/ 30/ 33/ 36 can be achieved by Sandblasting. Etching, Back Home

VDI 3400 Ref.39/ 42/ 45 by etching to be achieved VDI surface in our factory. 1、Etching is one of the basic process of mold texturing, using spray ink on the surface of the mold cavity as forming the basic grain and texture, after immersing in the acid liquid pool.
