All that remains is the name. Most texture houses can replicate each other's grains, but there seems to be a common misconception. Generally, texturing involves creating an array of patterns on the product's surface. Rougher textures provide better grip, and can also be used to hide minor molding defects like weld lines. When making molds, the VDI 3400 surface finish is primarily treated by Electrical Discharge Machining (EDM). Besides, injection molded snap fits are often more flexible and easily brave the rigors of parts assembly and disassembly. The right plastic surface finish can hide many of the tooling marks left behind during the injection molding process. VDI 3400 Surface Finish (known as VDI surface finish) refers to the mold texture standard Verein Deutscher Ingenieure (VDI), the Society of German Engineers. Injection Molding Surface Textures, Injection Mould Surface Textures, Gloss and surface topography, vdi 3400 surface finish standard First of all,we need to know about MOLD-TECH texture for most automotive moldings. Mold Texture Specification, injection mold texture standards, mold tech texture chart, Mold texture, SPI mold finish, edm texture chart, VDI surface finish. The Techniques Used to Apply Texture on Injection Molding Tools, EDM Spark Erosion, Electrical Discharge Machining (EDM), also called sparked erosion, uses an electrode placed in a dielectric bath of oil or water. Purpose of Texture, 1Improve product appearance. For example, a sandpapered plastic surface finish categorized as a "B1" is semi-gloss and lightly textured; a "B3" is still semi-gloss but has more visual and tactile texture. This process allows flexibility in creating the final appearance of your parts. In the US, many of the surface textures of injection molding products follow the standards set by the Society of the Plastics Industry or SPI.
