Everything you need to know about Foundries

Find answers to some of our popular questions on foundry equipment and processes here, and get in touch today.

What are the types of foundry?

Generally, sand foundries are categorised as one of two types: ferrous (dealing with iron or iron-based metals like steel), and non-ferrous (other types of metals like aluminium).  This is the primary category as it has the most impact on the equipment and methods used in the casting process.

What is chemically-bonded foundry equipment?

Foundry equipment covers all types of machinery, tools, and materials that are needed for the metal casting process. Omega Sinto offers a range of high-quality equipment that is specifically suited for chemically boned or ‘air set’ mould production. This equipment includes sand mixers, sand reclamation plants, mould handling, core making, coating plants, and our own cloud-based support service for online monitoring and maintenance of the equipment.

What is a continuous sand mixer?

In chemically bonded sand foundries, sand mixers are used to uniformly mix sand with a binder to produce an accurate sand mould and one that will stand up to the metal casting process.

What is waste foundry sand?

Waste Foundry Sand is sand that has been used in the casting process and contaminated with other items such as; residual binder, coatings, ceramic, metal, etc. This sand can then be cleaned graded, and classified sing various sand reclamation processes.

What is sand reclamation?

Sand reclamation is the process used to clean ‘contaminated’ sand and prepare it for reuse in the foundry by removing binding agents and metal remnants. This helps to reduce the raw materials that the factory uses, positively impacting cost, waste, and the environment.

What is thermal reclamation?

Thermal reclamation takes foundry sand that has already gone through mechanical reclamation, and passes it through a furnace where any residual binding agents are safely burned. This process aims to clean as close to 100% of the sand as possible, preparing it for reuse in the foundry.

What is core making in foundry?

Foundry cores create internal shapes and cavities. The core making process can be automated by use of a core machine or ‘blower’. In this case, the sand can be pre-coated with a binder and heat cured or gas cured.
