Read on to match the above techniques with the artwork and other castings we’ll discuss!
Piece molding is also conceived for multiple-use casting. This process employs a number of different molds, each creating a section of a more complex (and normally larger and more valuable) casting. As opposed to single-use waste molds, which are destroyed in the process of removing the casting from the mold, the bi-valve molds can be used several times. In this technique, a casting is made using two molds, one for each half of the object. Here are two simple techniques to give you an idea of the casting basics, although there are countless processes, in varying degrees of technical sophistication. They might be found in a foundry (a factory that produces metal castings). Some important pieces of equipment include a kiln and furnace. There’s a whole global industry run by skilled mold makers and sculptors who create the tools and machinery necessary for making molds. To help remove the casting from the mold, a release agent, or a chemical used to prevent other materials from bonding to surfaces, is usually needed. What you end up with is a solidified object also known as the casting. The liquid hardens or sets inside the mold, adopting its shape. Casting is the process of shaping liquid or a pliable material (this might be plastic, glass, metal, clay, epoxy, concrete, plaster or many other options!) is poured into the mold (or matrix).

Read on to learn more about the techniques, uses and history of mold making and casting, as we jump through time and land on select examples and periods of note! Many of the decorative and everyday objects you yourselves use have been made through various mold making processes! And increasingly, contemporary artists see them as the work of art in and of themselves.īut these processes also play leading roles outside of fine art, and support areas as varied as scientific research and mass manufacture in the automotive industries. In the world of art, the techniques of mold making and casting have served as tools by sculptors and other artists: in both studies that lead to the final form of an artwork, or as a means of reproducing an artwork. But their uses and applications are longstanding and varied, and also play a vast role in today’s arenas of artistic production and industrial manufacture. Mold making and casting are central techniques in the history of art and design.
