Self-Demolding Geometry in Flexible Silicone Molds
A return that peels is a one-piece mold. A return that locks is a split. Draw the demold direction before you pick Shore A.

Registration Keys for Two-Part Silicone Molds
Keys locate the two halves. They do not clamp the mold shut. If the seam flashes, look at the land and the close, not only the key.

When Does a CAD or 3D Modeling Fee Apply to a Silicone Mold Project?
Simple 3D is about USD 50 when we still have to model the cavity. A locked STEP file usually means that fee does not apply.
