Finishes for injection molding:
SPI Surface Finishes
These finishes determine the final appearance of the component, improving both aesthetic and functional qualities, depending on the type of surface desired. The SPI classification is divided into four main categories, ranging from maximum gloss to more matte and structured finishes, adaptable to design and performance needs.
- Category A: Mirror Polishing – Maximum brilliance, ideal for visible components.
- Category B: Semi-polishing – Moderate gloss, suitable for industrial applications.
- Category C: Matte Finish – Glare-free surface, reduces glare.
- Category D: Satin Texture – Specific textures for functional and decorative applications.
- Each category includes several subcategories that determine the degree of polish or texture.
VDI Surface Finishes
The VDI numeric scale indicates the roughness of the surface, from smooth to rough, with lower numbers corresponding to smoother finishes and higher numbers to rougher surfaces, ideal for industrial applications that require specific functionality. This system is essential to adapt the surface to the technical and aesthetic requirements of each project.
- VDI 12: Very smooth surface with minimal roughness, ideal for aesthetic components.
- VDI 15-21: Light to medium roughness, for applications that require functionality combined with aesthetics.
- VDI 24-33: Surfaces with increased roughness, suitable for technical and industrial applications.
- VDI 36-45: Rough surface, used for components that need wear resistance or anti-slip properties.
- The choice of finish depends on the aesthetic and functional needs of the final product.
