Manifolds are common auxiliaries in a plastics injection molding shop. They are key components of mold water cooling circuits. Their primary function is to route cooling water from the tower or chiller to the water passages in the mold, then collect the warmer water leaving the mold, at turbulent flow rates, and return it to the external cooling water loop.
In contrast, manufactured manifolds are engineered products that provide a convenient means to neatly arrange multiple water hoses. More importantly, they are designed to supply the mold water passages with adequate cooling water, then collect the warmer turbulent water flowing from the mold and return it to the external cooling water loop. Properly sized supply and return manifolds keep the backpressure effect from the return manifold leg of the cooling loop to a minimum.
Manifolds come in various shapes, sizes, materials and colors. When populated with auxiliary products, such as, ¼ turn ball valves, flowmeters, temperature indicators, and mold temperature regulators, they appear like spiny creatures.
