Injection Molding Surface Finish Sample Card with SPI & VDI Texture Standards – Mold Finish Reference Tool for Product Development

This injection molding surface finish sample card showcases how mold finishes can range from high-gloss to matte and textured patterns, with each finish applied directly to one side of the mold cavity and transferred precisely to the surface of the molded part. The samples feature industry-standard finishes from the Society of the Plastics Industry (SPI) and VDI injection molding finish systems, illustrating the visual and tactile differences achievable through tooling alone. Injection molding remains the most cost-effective method for producing consistent, high-quality plastic parts at scale, offering unmatched flexibility in material selection, color options, and surface finishes compared to other manufacturing processes.

• Features the full spectrum of Society of Plastics Industry (SPI) finishes, from Grade 3 diamond high polish to 320 stone low polish, including SPI A, B, C, and D series for visual and tactile comparison.
• Showcases VDI surface finishes defined by the Society of German Engineers, produced via EDM machining to achieve fine to coarse matte textures commonly used for functional and aesthetic parts.
• Injection molding is ideal for end-use parts, delivering superior consistency, surface quality, and durability compared to CNC machining or 3D printing.
• Represents finishes and processes widely used across aerospace, medical, automotive, electronics, robotics, consumer goods, toys, and other demanding industries.
