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 to accommodate regular cooling channels. Alternate methods for cooling these areas uniformly with the rest of the part involve the use of Baffles, Bubblers, or Thermal pins, as shown below. FIGURE 1. Baffle, bubbler, and thermal pin Baffles A baffle is actually a cooling channel drilled perpendicular to a main cooling line, with a blade that separates one cooling passage into two semi-circular channels.
