Branson MCX Series cleaners (photo) are ultrasonic systems purpose-built for cleaning plastics injection molds. They feature side-mounted, immersible transducers and powerful immersion heaters that can provide fast and efficient cleaning. Since most plastic injection molds are rectangular, with a lot of the design details on the surface facing the side of the tank, side-mounted transducers result in a more intense and focused cavitation as compared to bottom-mounted transducers. Compared to manual cleaning of plastics injection molds, which may take up to three hours or more, and may require toxic cleaning solutions, the Branson MCX Series can complete the job in 15 to 20 min, depending on mold design and level of residue, says the manufacturer. Branson ultrasonic cleaning systems use ultrasonic technology to produce fluid cavitation, enabling a non-contact cleaning process. Mold halves are placed between the transducers mounted on opposite sides of the tank, which is filled with cleaning solution. The system emits ultrasonic waves into the solution, creating bubbles that eventually implode, releasing energy. The resulting turbulence dislodges contaminants from all mold surfaces — even tiny holes and crevices where brushes cannot reach. — Emerson Industrial Automation, St. Louis, Mo.
