What is Casting

Casting is a process where liquid or semi-liquid material is poured into a mold. The mold is the inverse of the shape you want to make into a duplicate and comes in many shapes. It often contains a hollow cavity of the desired shape. Casting materials can be various cold setting materials, polymer, clays, hot melts, or metals. Cold setting materials typically may cure after mixing two or more components. Examples include: epoxy, concrete, plaster and clay.

Plaster and other chemical curing materials such as concrete and plastic resin may be cast using reusable mold making material. Using mold making material that is reusable allows for multiple casting projects from the same material and can save money and prevent frustrations.  By casting plaster, hydrocal, ultracal, concrete, or cement into your molds you can create unique sculptures, fountains, bird baths and more.

Cold set resin casting is used to make plastic casts. The mold is filled with a synthetic 2 part resin that is mixed together and hardens overtime. These casts can be used for small-scale production like industrial prototypes, toys, and jewelry. Hobbyists use plastic resins in their molds to reproduce collectible toys, rock walls, models, backdrops, broken parts, and figures. Jewelry makers use plastics resins to makes beads and earrings.

Clay and polymer clay are used for casting and is generally pushed into a mold.  Clays are plastic due to their water content and becomes hard, brittle and non–plastic upon drying or firing. Casting with clay is great for art projects and clay may be used to create a master for a mold. The polymer clay, such as Sculpey™ or FIMO™, or polymer metal clay is cast the same way as typical clay cast, by pushing the clay into the mold cavity.

Casting can also be performed using hot melt materials such as candle wax casting or soap castings. The process for making a wax casting or soap casting works through the melting of the soap or wax and pouring the liquid into the mold cavity. Instead of mixing two parts together, the wax or soap cools to solidify.

Casting is a useful tool to enable the duplication and creation of unique parts and shapes. There is anthropological evidence that people have been solving problems by casting parts since 500 B.C. So, if your favorite thing is broken and you want it replaced, consider making a mold and casting a part. For more information about molding and casting and associated materials visits
