3-Metal Molds
Metal is less commonly used for making gummy molds. It's mainly used for making chocolates. However, some people still use it for gummies. It’s because metal can provide immaculate and sharp edges to your gummies. Two metals are mainly used for this purpose.
Stainless steel is a highly durable, non-reactive, and food-safe material. On the other hand, Aluminum is lightweight and relatively inexpensive.

Pros & Cons of Metal Molds
