Process Cooling: Chillers Automatically Prevent Mold Condensation
A reported first from Delta T Systems is now standard on all its chillers.
Chiller controls now monitor ambient dewpoint and automatically adjust the cooling-water setpoint temperature at or above the dewpoint to prevent condensation on molds. This new and reportedly unique control feature has been made standard on all chillers fromDelta T Systems. By preventing condensation, this feature is said to decrease scrap rates caused by cosmetic defects from water droplets on the mold face, improve housekeeping, and lengthen tooling life by avoiding rust. Delta T says it is the first to offer such automatic protection as part of the chiller controls.
Modifications to the common core pin can be a simple solution, but don’t expect all resins to behave the same. Gas assist is also worth a try.
Anyone who operates a molding plant knows three things it cannot run without: raw material, electrical power, and cooling water.
For decades molding experts have talked about the importance of achieving turbulent flow in mold-cooling circuits. But what is it about turbulence that makes it so important? What can be measured and demonstrated to have some tangible value to molders? Several months ago, the author’s firm began looking for answers.
