Mold cooling system overview Importance of cooling system design Mold cooling accounts for more than two-thirds of the total cycle time in the production of injection molded thermoplastic parts. Figure 1 illustrates this point. An efficient cooling circuit design... by admin | Oct 17, 2018 | Mould Technology Blog 1
Cooling-channel configuration Types of 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 cooling channels are... by admin | Oct 17, 2018 | Mould Technology Blog 1
What do they do? Baffles and bubblers are sections of cooling lines that divert the coolant flow into areas that would normally lack cooling. Cooling channels are typically drilled through the mold cavity and core. The mold, however, may consist of areas too far away... by admin | Oct 17, 2018 | Mould Technology Blog 1
Cooling time Theoretically, cooling time is proportional to the square of the heaviest part wall thickness or the power of 1.6 for the largest runner diameter. That is: where the thermal diffusivity of polymer melt is defined as In other words, doubling the wall...
