Water Treatment Solutions for
Plastics & Injection Molding
Protect Your Molds. Optimize Cooling. Maximize Production.
In plastics manufacturing, water is critical for cooling molds, controlling temperatures, and maintaining product quality. HOH Water Technology delivers custom water treatment and glycol solutions designed specifically for plastics and injection molding facilities.
Common Challenges Plastics Manufacturers Face
Water quality issues directly impact the performance of injection-molded plastic components used in water treatment systems.
Scale buildup in mold cooling lines slows cycle times and causes uneven cooling, affecting part quality and throughput.
Corrosion damages molds and piping, leading to leaks, mold replacement, and production interruptions.
Generic antifreeze products can degrade in molding environments, causing corrosion or freeze protection failure.
Unexpected system failures disrupt 24/7 production schedules and inflate maintenance costs.
High turnover and limited water expertise cause inconsistent dosing and system neglect.
