A mold and a cast are both related to the process of replicating an object, but they serve different purposes. A mold is a negative impression of an object, while a cast is a positive replica made from that mold.
To understand the difference in more detail, I'll explain the process of creating a mold and a cast:
1. Mold:
- A mold is created by covering an object with a material such as silicone, rubber, or plaster.
- The material is carefully applied and allowed to harden or cure around the object.
- Once the mold is set, the object is removed, leaving behind a negative impression of its shape.
- The mold captures all the details and contours of the original object in a reverse manner.
2. Cast:
- A cast is created by pouring a material, such as resin or molten metal, into the mold created earlier.
- The material is allowed to dry or solidify, taking the shape of the mold.
- Once fully hardened, the cast is removed from the mold, resulting in a positive replica of the original object.
- The cast captures all the details and contours of the original object, but in a positive form.
In summary, a mold is the negative impression of an object, created by surrounding the object with a material that hardens to capture its shape. On the other hand, a cast is a positive replica made by pouring a material into the mold and allowing it to harden.
