Casting Patterns and Patternmaking Metal Casting Blog

Casting is the process of pouring liquid metal into a mold, where it cools and solidifies. The casting process can produce everything from art pieces to engine parts. The shape is determined by the mold cavity, but something needs to shape the mold—that’s where the pattern comes in. Patterns are a model for the object to be cast.

Foundry Pattern Making: Life of a Casting Reliance Foundry

In metal casting, patterns are the objects used to create expendable molds. A single pattern can make up to thousands of molds. There are different types of patterns, but they fall into two major subtypes: reusable ones for sand or plaster casting, which make impressions into many molds, or expendable patterns for investment casting, that are

Metal Casting Process Manufacturing Process

Like a pattern, the size of the core is designed to accommodate for shrinkage during the metal casting operation. Unlike a pattern, a core remains in the mold while the metal is being poured. Hence, a core is usually made of a similar material as the mold. Once the metal casting has hardened, the core is broken up and removed much like the mold.

3D printing casting masters means: Less production errors. Using the traditional method of a metal pattern means the potential for problems, such as incorrect shrink compensation and design flaws. This means the initial pattern often must be redone, which adds to the expense and lead time. 3D printed patterns do not have these issues.

Casting (metalworking)

In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.The metal is poured into the mold through a hollow channel called a sprue.The metal and mold are then cooled, and the metal part (the casting) is extracted.
