Injection molding surface finishes
SPI surface finishes
At 3D Berg, we follow the lead of the Society of the Plastics Industry (SPI) in setting the industry standard for plastics quality in the United States. This means that we utilize the SPI's comprehensive system to define the surface finish of our injection molded parts. With twelve different grades of finishes to choose from, spanning four different categories ranging from glossy to matte, we can deliver the perfect level of surface finish for your specific needs. Additionally, each grade comes with its own set of criteria for allowable deviation, ensuring that your parts are crafted to the exact specifications you require.
| SPI Finish | Guide | Typical Applications | Steel | Hardness |
|---|---|---|---|---|
| A-1 | Grade #3 Diamond | Lens / Mirror – requires 420 SS material | S136 | 54HRC |
| 8407 | 52HRC | |||
| A-2 | Grade #6 Diamond | High Polish parts | DF-2 | 58HRC |
| XW-10 | 60HRC | |||
| A-3 | Grade #15 Diamond | High Polish parts | S136 | 300HB |
| 718SUPREME | 300HB | |||
| B-1 | 600 Grit paper | Medium Polish parts | ||
| B-2 | 400 Grit paper | Medium Polish | ||
| B-3 | 320 Grit paper | Med – Low polish | ||
| C-1 | 600 Stone | Low Polish parts | ||
| C-2 | 400 Stone | Low Polish parts | ||
| C-3 | 320 Stone | Low Polish parts | ||
| D-1 | Dry Blast Glass Bead | Satin finish | ||
| D-2 | Dry Blast # 240 Oxide | Dull Finish | ||
| D-3 | Dry Blast # 24 Oxide | Dull finish |
VDI surface finishes
Similar to the SPI standard for plastics quality in the United States, the VDI (Verein Deutscher Ingenieure) standard sets the benchmark for the engineering industry in Germany. At 3D Berg, we adhere to the VDI's rigorous standards when it comes to designing and manufacturing our precision injection molded parts. By following the VDI's exacting guidelines, we can ensure that our products meet the highest levels of quality and precision, delivering outstanding performance and longevity for your specific application. Whether you need parts that can withstand extreme temperatures, resist corrosive materials, or provide superior strength and durability, we have the expertise and resources to deliver exceptional results.
