Diamond polishing creates the finest finish for highly visible or lens-quality parts. The SPI* A-2 is the most widely used diamond finish, with excellent release and appearance. The SPI A-3 is ideal for release where a high-gloss appearance isn't required. All diamond finishes work well with chrome and nickel coatings.

Paper finishes are the second most-refined option after diamond polishing. They produce a slightly reflective or glossy shine and a very good release. Choose paper finishes for products that don’t require a decorative or visual effect.
Stone finishes are the most economical polishing option. They’re a good choice for strictly functional molded parts where aesthetics don’t matter. Stone finishes provide a good release and deliver very little gloss to the plastic part. They’re also the first step in the process of diamond and paper polishing.
