About tooling manufacturing
Mold making is the process used to duplicate three dimensional models or objects. A model is an object that has depth, and an original model can be made from almost anything. If you were making your own object to mold, you might use clay, rock, or plastic. Through the use of a mold-making material a negative, or a reverse, of a model part is made, the negative can then be used to cast a second part that is the same size and shape as the original part.
Molding is a manufacturing process that involves shaping a liquid or malleable raw material by using a fixed frame; known as either a mold or a matrix. The mold is generally a hollow cavity receptacle, commonly made of metal, where liquid plastic, metal, ceramic, or glass material is poured. In most cases, the mold is derived from the initial pattern or template of the final object; its main objective is to reproduce multiple uniform copies of the final product. As the liquid cools and hardens inside the mold, the final configuration is achieved. Its removal is facilitated by the use of a release agent or ejection pins.
