Pattern Making
The way sand casting works is the patternmaker makes a positive object that is placed in a bed of wet sand and then removed, forming a cavity that is filled with molten metal. The metal shrinks a bit on cooling, so the pattern needs to be slightly larger than the final product to account for this shrinkage.

Sand Core Making | Sand Casting Core | Harrison Castings Ltd
Cores are produced by blowing, ramming or in heated processes, investing sand into a core box. The finished cores, which can be solid or hollow, are inserted into the mold to provide the internal cavities of the casting before the mold halves are joined. Sand cores are also widely used in die-casting, where permanent metal molds are employed.

Foundry Pattern Making & Capabilities | Harrison Castings Ltd
Pattern making is one of the first and most important steps in the casting process. Though many factors can have an impact on quality, a casting is only ever as good as its tooling. For efficient and cost-effective castings, high-quality foundry pattern making is of vital importance.

Shell cores can be solid, smooth with high definition. The shell process can also be used to create molds providing a casting with excellent finish and minimum cleaning room processing. The shell core can be cured with either electrical heated platens or gas fired systems, and the uncured sand can be re-used after collection.

Sand casting patterns can also be used to carve the sand, rather than impressing a shape into it. A sweep pattern spins a blade with a shaped profile around an axis, hollowing out a mold. It is helpful to think of sweep patterns like a lathe that shapes negative space: the cast objects they make will have symmetry around a central axis.

Core (manufacturing)
The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in die casting and injection moulding. For example, cores define multiple passages inside cast engine blocks. One model of GM V-8 engine requires 5 dry-sand cores for every casting.

Sand casting
Sand casting. Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.

Sand cores are removed from metal or plastic coatings by exposing the cores to a humid atmosphere for a sufficient time to weaken the binder of the sand cores. The sand is then shaken from the casting. Metal or plastic castings with hollow passages are produced by forming a casting around the sand core bound with a suitable binder followed by

Besides the advantage of an emission-free core production process these systems reduce the core gas production during the casting process, improving the casting quality. For the hardening of the sand core the water must be removed from the core which is typically accomplished by the injection of hot air.

to allow the sand core to be withdrawn from the box after the core has cured. Fillets Sharp, internal corners on a casting design should be avoided whenever pos-sible. The small volume of mold media located in a casting’s internal corner quickly becomes superheated and limits the casting’s ability to transfer heat at this location.

The core box is purged for a set time to allow the core to harden. The duration depends on the shape and size of the core. The main advantage of this technique is that no heating is required and the sand is evenly distributed into the core box, allowing it to fill hard-to-reach corners and cavities.
