Dry ice systems for foundry operations

Tools, moulds and boxes must be cleaned regularly and thoroughly in a foundry – in this process, it is important to pay attention to quality and costs. Dry ice cleaning by the company Cold Jet from Weinsheim focuses exactly on these challenges. In this type of cleaning, no water or chemicals are used and no secondary waste is produced.

Dry ice in the form of blocks or pellets is used for blast cleaning. Depending on the application, a choice can be made between a 3-mm pellet blasting system or a universal scraping technology that allows any form of dry ice. The company based in Weinsheim offers solutions that require less dry ice and air pressure and are specially designed for the requirements of the foundry industry. The company also offers combination systems, which combine pellet production and blasting in one system and are suitable for robotic use.

One of Cold Jet's industrial focuses is the manufacture of dry ice production equipment. Liquid CO2 is used to produce dry ice. During the conversion process in the pelletiser chamber, only 50% of the liquid is used to produce CO2 snow and the other half is converted into revert gas. The pellets are created from the CO2 snow, while the gas normally escapes unused. With the company's recovery system, the revert gas is recycled and used again for the production of pellets. This can reduce costs by 50%. Another advantage of these recovery systems is that they can be integrated into all dry ice production systems.
