Injection Molding Finishes
|
|
Standard Finish
|
Moldmaker's choice of finish. Typically SPI B-2, depending on geometry and drafts. Interior, non-cosmetic faces, are typically as-machined. |
SPI Finishes
|
Range of Society of Plastics Industry (SPI) finishes from Grade 3 diamond / high polish to 320 stone low polish. Finishes include: SPI A-1, SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3 |
Other Textures - VDI
|
VDI 3400 Surface Finish (commonly known as VDI surface finish) refers to the mold texture standard set by Verein Deutscher Ingenieure (VDI), the Society of German Engineers. This is mainly processed by EDM machining, producing fine to coarse matte finishes. |
Threaded Inserts
|
We can install most commonly used standard inserts in UNF and metric sizes.

Injection Molding Design Guidelines
|
|
Undercuts
|
Reduce undercuts, which will increase the complexity and cost of the tool ejection mechanisms, by adding in pass-thru coring.
|
Wall Thickness
|
Prevent wall sink and voids by maintaining an even wall thickness. Thinner walls reduce cycle time and reduce costs.
|
Drafts
|
Ensure parts are designed with a minimum draft angle of 0.5°, or up to 5°, for faces with medium textures.
|
Ribs/Gussets
|
Ribs should be 40-60% the thickness of outer walls and should still maintain draft.
|
Bosses
|
Bosses should be designed at a depth of 30% the wall thickness and with a 30% edge groove. Attach them to side walls or ribs for
structural integrity.
