Mold Texture and SPI Finish

Mold Texture is also known as Grain. It refers to the rough surface finish; the opposite one is called Gloss Finish. It refers to the smooth finish. VDI 3400 texture is the most common texture standard. For the smooth finish, SPI finish is the standard of this kind.

  • For surfaces that will be textured, a 3° – 5° draft angle is required
  • Please do not change the texture after molding, as texture changes, so as the draft. The molds may not be machined again.
