Mold Cooling Channels (Water channels) is one of the important systems in plastic mold, Water Cooling lines plays the role in molding process that could improve distortion, tolerance, cycle time, sink mark, and so on, poor Cooling Channels will never able to got high quality molding parts.

A single fundamental rule of injection molding is that hot material enters the mould, where it cools rapidly by cooling channels in the mold to a heat at which it stiffens enough to keep the pattern of them. The heat of the plastic mold tooling is for that reason important as it governs a portion of the general molding cycle.

While the melt runs more freely with […]

Types of Mold Cooling Channels

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

FIGURE 1. Cooling-channel configurations

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 […]
