Injection Molding
Automatic filtration for injection molding cooling circuits where clean water helps preserve heat-transfer efficiency and mold performance.
When dealing with Injection Molding, there are many water quality issues that must be addressed through filtration.
- Injection molding cooling circuits can accumulate scale, corrosion products, and suspended fines.
- Blocked cooling passages reduce heat transfer, increase cycle time, and create quality variation.
- Manual cleaning of cooling loops and strainers can interrupt production schedules.
Conditions, Contaminants, and Considerations
Water sources may vary, but the primary water sources for Injection Molding filtration are:
- Cooling water
- Closed-loop water
- Cooling tower water
- Makeup water
In this application, water is usually filtered within the 100-300 micron range to remove contaminants like:
- Scale
- Corrosion products
- Fine solids
- Biological debris
Due to these constraints, certain design considerations must be made to accommodate variables that can interfere with the filtration process. Factors such as Cooling circuit flow, Mold sensitivity, Water chemistry, Micron rating, Pressure drop, and Maintenance access must be accounted for to ensure reliable and efficient water filtration.
Benefits
Filtering the water before industrial or commercial use:
- Protects cooling passages, pumps, valves, and heat exchangers.
- Helps maintain cooling efficiency and consistent process conditions.
- Reduces manual strainer cleaning and disposable filter maintenance.
Relevant FAQs
Does the filter waste a lot of water while cleaning itself?
No, because of how quickly the filter cleans itself. Typical backwash water volume is as little as 10 gallons.
