#62 – Mould Closure

Closing moulds correctly is vital to get good casts out of them. There seems little point in making a good mould and then getting bad casts out of it.

In this episode, we take a look at things to consider in ‘mould closure’. Essentially, a mould other than a flat or open mould will usually need to be attached or fitted to another component to produce a cast.

This could be another part of the mould if a ‘multi-piece’ mould is made and/or a core which will be placed into the mould to create the interior.

These pieces need to remain securely in position, and may be required to exert a lot of force if the cast piece needs to have thin seams which are more easily repaired.

That has cost implications – think about having to repair bad seams of fifty casts out of a mould which wasn’t closed correctly! Small block moulds are often clamped together for speed and convenience, but what happens if the mould is huge, such as a full body or a dinosaur?

Check out the notes included with this episode for a deeper dive with pictures.

In the podcast, Todd mentioned a cool gargoyle figure (pic below) that has an Oni demon style face that he was going to mould. We chat about risers to reduce the air bubbles that could be trapped in the mould, a common issue with smaller pieces with tight details.
