Surface Finishes Are Available for Injection Molded Parts? 
Sanding Removes gate vestiges, parting line flash, and ejector pin marks (Ra 0.8–1.6 µm).
Polishing SPI A-1 diamond polish for mirror finish (Ra 0.012–0.025 µm) used in optical lenses and light guides. 
Texturing Mold-Tech and VDI textures (SPI C-1 to D-3, Ra 0.8–3.2 µm) to obscure sink marks, improve grip, and reduce fingerprints. 
Electropolishing Applied to S136 and H13 steel mold cavities (Ra 0.05–0.1 µm mold finish) for smoother part release and extended mold life. 
Anodizing Hard-coat anodizing (Type III) on aluminum prototype molds adding 25–50 µm wear layer to extend shot life to 10,000+ shots. 
Vibratory Finishing Batch deburring to remove gate nubs and parting line flash uniformly (Ra 0.8–1.6 µm).
