Mold Class Glossary

Mold Class Glossary
NameCyclesDescriptionExample
Class 105 toolUnder 500Prototype 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 toolUnder 100,000Low 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 toolUnder 500,000Medium 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 toolUnder 1,000,000Medium 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 toolOver 1,000,000Built 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.
