What is meant by “Flash” and “Bubbles” on a Resin Model kit?
A. When the two halves of the model mold come together and is injected with resin, some of the excess resin squeezes out along the edges and then hardens. When the two halves are separated and the resin model is pulled from the mold, you can see the excess resin along the edges where the two halves of the mold can together; The excess material is referred to as “Flash”. “Flash” can also be found on plastic models since injection-molded models are made in a similar method. “Bubbles” refers to little pockets of air that gets trapped in the resin as it cures inside the mold. When these pockets of air cures close to the surface of the model, they form small crater like pits commonly referred to as “Bubbles”.
