My company has started an injection molding facility back in June of 2011 in Arizona. I expected a fairly smooth start up due to the cookie cutter operational set up from another facility and we also were dealing with all new machinery and injection molds.
Soon after the startup we saw serious flow issues with small cooling circuits in our hot runner valve gate system. Due to the location of our facility, we were blessed with hard water in our region causing our cooling tubes to build up with scale. Our initial plan was to incorporate flow meters for those circuits to monitor flow rate and we incorporated a system coolant flush to our preventive mold maintenance. However, we still saw periodically cogged cooling channels in production.
I came across an advertisement for a digital calcium de·scaler from DME and decided to purchase a DSC100 version, which I installed together with a sediment in-line water filter on a pilot production line back on 5·14·12.
Already after 10 days of continues operation the flow showed signs of improvements. The flow meter sight glass started to clear up and the actual flow rate increased by 20% on all affected circuits. The flow rate has been steady since the install and I will move forward to apply this set up on all our production lines.
"If you have issues with hard cooling water in your area, I can highly recommend the Digital Calcium De-Scaler offered by DME Company LLC."
