Can the Imperium build new Forge Worlds?

Yes, the problem is production and resources. Certain forgeworlds are able to produce certain things chiefly because they have the necessary schematics to do so, which they are loathe to share with other forge worlds, this presents a problem in that the mechanicus can build new forheworlds and begin new production, but they wouldn’t necessarily be able to build new things, only much the same as they already build. The other side is resources, not many mechanicus personell would have the necessary resources to find a suitable planet and then build a forgeworld upon it and then protect it long enough to be worth the effort, especially if that forgeworld wouldn’t produce something they already produce at their own forge.

Why expend costly resources to expand production when you don’t need or have to, especially when their is a likelihood of needing said resources in case of emergencies or the new forgeworld being destroyed or looted while it is vulnerable.
