An SPI A-1 Diamond Finish is a specialty of Bales Mold Service. We u it to produce the finest finish on molds, producing highly visible or lens quality parts. The SPI A-2 is the most widely ud diamond finish, providing good relea and good visual parts. An SPI A-3 is a fine choice for relea where a high gloss appearance is not required. All diamond finishes work well with chrome and nickel.
the esntial 55 Paper Finishes, SPI B-1 to B-3 – Next to diamond polishing, paper finishes are the cond most refined finishes available. Paper finishes produce a slightly reflective or glossy shine and very good relea. They are often recommended for products that do not require a big decorative or visual impact.
Stone Finishes, SPI C-1 to C-3 – The most economical finish, stone finishes are also the first step in the process of creating both the paper and diamond finishes. Stone finishes provide good relea but very little gloss to the plastic part. This is a good choice for strictly functional molded parts where aesthetics are of no importance.
Blast Finishes, SPI D-1 to D-3 – When done properly, blasted finishes can produce some of the most interesting stipples and textures on mold surfaces. From a fine satin texture with varied degrees of gloss to a flat, no-gloss coar stipple, Bales has the blast
media to produce the proper finish for you. Blast finishes are also an excellent way to camouflage weld repairs and slight imperfections.
