Types of Mold Cooling Channels
Cooling channel configurations can be serial or parallel. Both configurations are illustrated in Figure 1 below.

Parallel cooling channels
Parallel mold cooling channels are drilled straight through from a supply manifold to a collection manifold. Due to the flow characteristics of the parallel design, the flow rate along various cooling channels may be different, depending on the flow resistance of each individual cooling channel. These varying flow rates, in turn, cause the heat transfer efficiency of the cooling channels to vary from one to another. As a result, cooling of the mold may not be uniform with a parallel […]
