Yes, we can provide a high-definition digital VDI 3400 texture chart pdf for your mold design and surface finish reference. Our technical resources cover the full spectrum from VDI 12 to VDI 45. Furthermore, since digital screens may vary in display performance, we highly recommend purchasing our physical steel plaques to ensure 100% accurate visual and tactile evaluation before final texture approval.
The visual effects are similar, but the microscopic shapes are different. EDM are random discharge pits, while VDI 3400 spark erosion texture samples (especially laser) particles are more regular. Laser etching has a more uniform draft angle, which is more conducive to demolding.
The crucial difference lies in their classification methodology. The Mold-Tech MT 11010 standard defines a specific, copyrighted pattern texture geometry, focusing heavily on aesthetic texture appearance. On the other hand, the VDI 3400 standard (Charmilles scale) specifically quantifies surface roughness grades based on Ra values. As a leading manufacturer in China, We can provide MT 11010 vs VDI 3400 texture comparison between the two to ensure your products meet technical specifications worldwide.
Custom Capabilities: We can manufacture Metal, Aluminium, Copper, and Plastic plaques in custom sizes.
For VDI 3400 Ref. 12 . 15 . 18 . 21 . 24 . 27 . 30 we use Sandblasting. For VDI 3400 Ref. 33 . 36 . 39 . 42 . 45 or CHARMILLES EDM standard, we utilize advanced Acid Etching to achieve high-precision effects for electronics like laptops and printers.
