Mold Class Glossary

Mold Class Glossary

Class 105 tool


Under 500


Prototype only. This mold will be constructed in the least expensive manner possible to produce a very limited quantity of prototype parts. Also known as a Class V tool.


A one-and-done market test of 100 molded units.


Class 104 tool


Under 100,000


Low production mold. Use only for limited production preferably with non-abrasive materials. Low to moderate price range. Also known as a Class IV tool.


Aluminum or MUD tooling, SPI B-3 finish, hand-loaded cores and limited re-runs.


Class 103 tool


Under 500,000


Medium production mold. This is a very popular mold for low to medium production needs. Most common price range. Also known as a Class III tool.


Aluminum or steel tooling, automated lifts or slides, multiple re-runs with batches between 1,000-5,000 units.


Class 102 tool


Under 1,000,000


Medium to high production, good for abrasive materials and/or parts requiring close tolerance. This is a high quality, fairly high priced mold. Also known as a Class II tool.


Steel tooling with an SPI A-2 finish, automated slides, scheduled production cycles.


Class 101 tool


Over 1,000,000


Built for extremely high production. This is the highest-priced mold and is made with only the highest quality materials. Also known as a Class I tool.


Multiple-cavity steel tooling with full automation and overnight production workcenters for dedicated part manufacturing.

The injection molding industry often defines molds by their class. This goes from Class 105, a prototype mold (e.g., a 100 piece one-and-done market test), to Class 101, which is built for extremely high production (e.g., making tens-of-millions contact lens cases). Xometry typically produces Class 104, 103, and 102 tools.

Medical Injection Molding Finishes

Standard Finish

Moldmaker's choice of finish. Typically SPI B-3 to D-3 depending on geometry and drafts. Interior, non-cosmetic faces, are typically as-machined.

MoldTech Finishes

Range of finishes including matte, swirls, lines, and patterns. Finishes include: MoldTech - MT11010 MoldTech - MT11020 MoldTech - MT11030 MoldTech - MT112XX MoldTech - MT114XX MoldTech - MT116XX

SPI Finishes

Range of 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

As Molded

No secondary polishing or grinding. Part will show tooling marks.

Other Mold Texturing

Xometry can match other mold textures upon request.
