Texture Selection Guide for Injection Molding

Use this guide when the team has three catalogs and one deadline.

Surface finish

Choose texture in four decisions

Appearance, touch, hide power, and mold cost trade off in that order.

Start from user touch and glare, then pick a catalog entry that matches.

Run draft checks after texture depth is chosen, not before.

Decision path

Fast pick versus documented pick

Documented picks survive supplier changes.

Verbal 'light texture'

  • No catalog number
  • No witness sample

Written catalog reference

  • SPI, VDI, or MoldTech on drawing
  • Hub links to deep dives

Quote checklist

What to send with CAD

Finish specs stall quotes when they live only in email threads.

  • Primary catalog chosen

  • Secondary faces defined

  • Link to color spec if appearance critical
