For injection molders like Central Can Co., the two most important parameters for mold cooling are flow rate and temperature.

For injection molders like Central Can Co., cycle time is everything. The two most important parameters for mold cooling are flow rate and temperature. With the closed-circuit dry cooling system’s chiller/temperature controllers, the temperature and flow requirements are created at each individual mold, thus reducing cycle time and increasing productivity.

“While we initially chose the Ecodry system because of its ease of maintenance, it turns out that the cycle time factor has been the real star of the system,” said Ruba. “The ability to open up a month’s worth of capacity on our machines is a great help in our ability to serve our customers better and faster while operating more profitably as well.”

In Central Can’s facility, all temperature control units are set independently of one another, allowing water to flow to the machine at the exact temperature needed for optimal part production and faster cycle times.

A single temperature control unit can both heat and cool a machine at the same time, thus allowing different temperatures in multiple zones. It replaces the need for individual portable chillers and temperature control units at each machine and costs much less as well.
