As the name suggests, cooling channels are channels in a mold through which a cooling agent (like coolant or water) can flow to accelerate the cooling process and make it more uniform. See moreInsufficient or improper cooling channels can cause a number of problems, including: 1. Insufficient or uneven cooling can lead to deformations throughout the part as areas cool at different speeds. Proper cooling prevents parts from warping or shrinking. .

Regardless of which type of cooling channels you use, there are several important factors you must consider in your design, . See more
There are two primary types of cooling in injection molding — traditional cooling and conformal cooling. Each one is built on the general concept of cooling channels through which . Conformal cooling improves plastic molding through precision-engineered cooling channels. Most of these channels correspond to part geometries, so the cooling effectiveness . There are two primary types of cooling in injection molding — traditional cooling and conformal cooling. Each one is built on the general concept of cooling channels through which a cooling agent (such as coolant or water) can flow.
Thanks to 3D printing technology, there are now two different types of cooling channels. Standard/Traditional Cooling. Traditionally, cooling channels were straight lines created by drilling or milling into the mold. Standard cooling channels may cross or be enhanced with other devices like bubblers or bafflers.
The goal when locating cooling channels in the mold is uniform mold surface temperature, which is determined by cooling channel depth and pitch. Consider the following examples of cooling channel configurations in P20 mold steel with a water line diameter (D) of 11.1mm (7/16"), coolant temperature of 30ºC and cycle time of 17 seconds (see Fig. 3). Conformal cooling improves plastic molding through precision-engineered cooling channels. Most of these channels correspond to part geometries, so the cooling effectiveness is much higher. This approach reduces production time by . But recently, new technology has made conformal cooling channels both easy and affordable to produce. Direct metal laser sintering (DMLS) can create parts with highly complex external and internal geometries, “manufacturing” the cooling channels along with the tooling inserts—in a single process. Basic guidelines will take advantage of the properties of both the coolant and the cooling channels: The spacing of the cooling channel from center-line to center-line (pitch) should be no more than 3 times the diameter (3D). The distance from the cooling channel to the cavity surfaces should be no more than 1.5 times the diameter (1.5D).
Conformal cooling channels (CCCs) achieve better cooling performances than the conventional (straight-drilled) channels during the injection molding process since they can follow the pathways of the molded geometry while the conventional channels fail. Cooling channels are mandatory in molds to force the injected materials to cool down, and usually consist of a series of straight-drilled channels. The cooling system is an important part of the injection mold. The coolant continuously flows in the cooling water channel inside the mold, taking away the excess heat in the mold, thereby ensuring that the mold temperature is controlled within an appropriate range. The reason for this is simple – it’s just better. By creating conformal cooling channels that follow the unique geometry in the mold tool of an injection molded part, engineers can perfectly optimize their cooling lines.
