The Society of the Plastics Industry, or SPI, establishes standards for the United States plastics industry. Among the SPI standards is one defining the degree of polish on the inner surfaces of the molds used to form plastic products. The SPI standards specify 12 grades of mold finish ranging from mirror-perfect to dull. Various companies offer illustrative sample kits consisting of steel discs or strips polished to the different SPI grades.

SPI Surface Finish Standards
