Low-pressure area Low-pressure area A low-pressure area, low, depression or cyclone is a region on the topographic map where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis. Within the field of meteorology, atmospheric divergence aloft occurs in two areas. The first area is on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). A second
Low pressure molding to replace heat shrink tubings. Since then Low Pressure Molding has spread out to other areas such as industrial products, medical, consumer products, military, wire harness and any unique product that needs to be sealed and protected against the environment, like Automotive sensors in-cabin and even under hood, USB thumb drives, RF ID tags, moisture sensors, motor control boards, consumer products. In essence the process acts as a middle ground between plastic injection molding which subjects components to high pressure and temperatures that can often damage them and potting with resin a process that involves waste and lengthy curing times.
