SPI Finishes Range of finishes from Grade 3 diamond / high polish to 320 stone low polish. Finishes include: SPI A-1 SPI A-2 SPI A-3 SPI B-1 SPI B-2 SPI B-3 SPI C-1 SPI C-2 SPI C-3 SPI D-1 SPI D-2 SPI D-3

As Molded No secondary polishing or grinding. Part will show tooling marks.

Other Mold Texturing Tiandiao can match other mold textures upon request.

Overmolding Design Tips • Wall thicknesses between 0.060" to 0.120" (1.5 mm-3 mm) generally provide the best bonding.
• Keeping radii between 0.020" or 0.5mm minimum in corners reduces localized stresses.
• If the part requires the use of thick TPE sections, they should be cored out to minimize shrinkage problems, reduce the part weight and lower cycle time.
• Avoid deep or un-ventable blind pockets or ribs in your design.
• Use gradual transitions between wall thickness to reduce or avoid problems with flow (back fills, gas traps, etc.)
• The TPE/TPV should be less thick than the substrate to prevent warpage, especially if the part is flat, long, or both.
• Overmolding needs mechanical or chemical bonding to the substrate, so your material choices should enable this.
