Core machines

Cores are used to determine the shape of the casting, which cannot be determined with a mold or tool. Foundry cores are used in sand moulds, gravity and low-pressure casting. The basis of the core is sand, which retains the shape of the tool with the help of a chemical binder.

There are various types of core machines on offer. Basically, they can be divided according to production processes:

• Cold hardening processes: Cold box, CO2, Beta set, etc.
• Hot hardening procedures: Croning, Hot box

Depending on the configuration of the cores, the machines can be:

• With vertical tool division
• With horizontal division
• Combined

With regard to the necessary capacities of the machines, they are divided into

• Manually controlled
• Automatic machines
• Highly productive multi-station centers.
