Water Treatment for Plastics and Injection Molding
In plastics and injection molding, water plays a critical role in process cooling, equipment performance, and maintaining product consistency. Water treatment helps prevent scale buildup in molds and chillers, ensures consistent cycle times, and reduces maintenance and overall energy costs. At Culligan Texas, we provide customized water treatment solutions designed to meet the unique operational needs of plastics manufacturing facilities.
For over 74 years, Culligan Texas has delivered high-performance water treatment solutions tailored to the demanding needs of plastics and injection molding operations, such as:
- Cooling Water Treatment – Prevent scale, corrosion, and biological growth in molds, chillers, and cooling towers to maintain consistent cycle times and reduce equipment wear.
- Process Water Purification – Provide clean, contaminant-free water to support precision molding and reduce the risk of defects or discoloration.
- Closed-Loop Water Systems – Optimize water reuse in cooling applications to lower consumption and operating costs without compromising performance.
- Filtration & Pretreatment – Remove particulates, chlorine, and other contaminants that can impact water-cooled processes and degrade equipment.
- Wastewater Management – Treat and recycle water from cleaning or production areas to help meet environmental regulations and reduce discharge volumes.
Water Quality Targets & Treatment Insights for Plastics and Injection Molding
- Chiller systems need low TDS (< 50 ppm) to prevent scaling and corrosion in mold cooling circuits.
- Untreated cooling water can cause scale buildup in mold passages, dramatically increasing cycle times—from about 11 seconds to 29 seconds over 2,000 hours of operation.
- Chemically treated chilled or tower make‑up water (hardness < 80 ppm, pH ~7.2–7.8) enables 3–6 cycles of concentration, balancing efficient water use while preventing scale.
- Closed‑loop chilled water must be treated to inhibit corrosion, scaling, and microbial growth to maintain consistent cooling and protect molds and hydraulic systems.
