FAQ

1.Is there a minimum order quantity (MOQ) for Injection Molding? Can you support low-volume production?

The MOQ depends on the part size and project conditions, but in most cases the typical MOQ is around 1,000 units.

2.How many parts can be produced from a single mold? (Mold life)

A standard production mold typically supports 300,000–500,000 shots or more, depending on the mold material, part geometry, and processing conditions.

3.Can the design of an existing mold be modified after it has been manufactured?

Modifications are technically possible, but additional costs may apply. Mold changes generally require welding and secondary machining, which can lead to slight differences in surface texture—especially in areas with surface treatments. Because the modified areas may not appear perfectly uniform, mold modification is generally not recommended unless necessary.

4.What is an “Undercut,” and how is it resolved in injection molding?

An undercut refers to a feature—such as a hole, hook, or protrusion—that prevents the part from being ejected straight out of the mold along the opening direction.


To accommodate these features, additional mechanisms such as slides or lifters are incorporated into the mold. However, these mechanisms increase mold complexity and tooling cost. Creallo therefore recommends design strategies that minimize undercuts whenever possible. Please refer to our Design Guide for more information.
