Germany | Leichtmetallgießerei Bad Langensalza cleans its casting molds daily with an ASCOJET 1701 dry ice blasting machine. The dry ice pellets used for this purpose are produced on site with an ASCO A120P dry ice pelletizer. According to General Manager Hagen Stein, quartz sand was previously used to clean the molds. But that method subjected the molds to much heavier wear. Moreover, the machines’ hydraulic cylinders required more frequent maintenance because quartz sand deposits caused the seals to wear. The use of dry ice blasting has lowered costs and made the cleaning process more efficient.
