Plastic Injection Molding Finishes
Mold finishing ranges from glossy to matte to uniform patterns. The finish applied to the mold cavity surface transfers to the surface of the molded part. For example, a mold surface polished to be reflective will make a reflective (or clear) part. Mold finishing differs from CNC machined or 3D printed parts, where each component is processed individually. Adding a finish or texture can change the price of the tool depending on the process required, but it does not change the price of the individual parts.
SPI A Finishes
- SPI A-1：Diamond buffed with grade #3, 6000 grit for a highly polished finish. Also suitable for producing optically clear parts. Has an average surface roughness of 0.012-0.025µm Ra.
- SPI A-2：Diamond buffed with grade #6, 3000 grit for a high polish finish. Also suitable for producing transparent parts. Has an average surface roughness of 0.025-0.050µm Ra.
- SPI A-3：Diamond buffed with grade #15, 1200 grit for a high-to-medium polished finish. Also suitable for producing non-optical transparent parts. Has an average surface roughness of 0.050-0.100µm Ra.
