Pure Water Treatment System
- Recycling and Reuse Maximize Water Resource Value
Traditional workshop water usage follows a “single-use discharge” model, which not only wastes large amounts of water but also increases production costs due to high sewage treatment expenses. The circulating pure water treatment system, with its closed-loop design, deeply purifies used wastewater and converts it back into pure water that meets production standards for reuse. This achieves a water recycling rate of over 90%. As a result, workshop water consumption is greatly reduced, water expenses are cut by more than 60%, wastewater discharge is lowered, and environmental treatment costs are decreased—delivering the dual benefits of “water savings cost reduction.”
- High-efficiency water pretreatment system.
- Improves the overall water quality of the entire die casting workshop.
- Dual-station coordinated operation ensures continuous water supply.

The cooling and cleaning stages of die casting parts require extremely high water purity. If impurities or ions in the water exceed the standard, they may cause oxidation spots or rust marks on the surface of castings, and even affect the precision of subsequent spraying and assembly.
The circulating pure water treatment system uses core technologies such as multi-stage filtration, ion exchange, and reverse osmosis to precisely remove suspended matter, heavy metal ions, microorganisms, and other contaminants from the water. This ensures that water purity consistently meets the industry’s strict standards.
Stable and continuous pure water supply guarantees that every cooling process is uniform and efficient, and every cleaning step is thorough and clean. By addressing water quality issues at the source, it reduces product scrapping and safeguards the precision quality of die castings.
