Introduction of a case study on preventing cooling scale in aluminum die-casting molds through hydroflow installation.

We will introduce a case of scale prevention for the aluminum die-casting mold cooling system using the "Hydroflow Electromagnetic Water Treatment Device." The user is ED Industry Co., Ltd. (an aluminum die-casting manufacturer in Shizuoka Prefecture). The silica content in the well water is high at 48 mg/L, and when scaling occurs, it becomes a very hard scale, leading to a significant decrease in production efficiency and necessitating installation to prevent the occurrence of defective products. The equipment used includes five aluminum die-casting machines and an oil cooler. 【Installation and Effect Confirmation】 ■ Installed Model: Electromagnetic Water Treatment Device "Hydroflow," Model: P60×1 unit ■ Usage Period: From July 14, 2011, to November 21, 2011 (four months) ■ Regular checks on the scale adhesion condition of the jet cooler pipes - Before treatment: Replacement was done every 25,000 to 35,000 shots - After treatment: Extended to 90,000 to 95,000 shots ⇒ Significantly contributed to efficiency improvement For more details, please refer to the catalog or feel free to contact us.

【Other Effect Confirmation】 [Regarding Scale Precipitation] ■ Before installation, there were no scale deposits in the tank, and the entire tank appeared green due to the growth of algae. ⇒ After 5 months of installation, it was confirmed that scale, which was supposed to adhere to the equipment, had precipitated in the tank. Additionally, there has been no algae growth, and the tank remains clean. [Effect Against Algae Prevention] ■ Before treatment, algae were present on the walls of the tower and the packing material. ⇒ After 5 months of treatment, the algae have died and turned black, with some peeling off. *For more details, please refer to the catalog or feel free to contact us.
