Mold making is the process of creating a hollow container, known as a mold, which is used to shape materials like plastic, metal, or ceramic. The mold is typically made from materials such as silicone, rubber, or metal, and it allows for the reproduction of a specific shape or design. Once the mold is created, it can be filled with the desired material to produce a replica of the original object. This technique is widely used in various industries, including manufacturing, art, and construction, to create items ranging from toys to automotive parts.
