| The use of ultrasonic cleaning for routine injection mold maintenance has been effectively employed for many years. As a non-contact method, mold detail is not damaged during cleaning and critical tolerances can be maintained, extending mold life. The high cleanliness level achieved with ultrasonics results in better part release and longer runs. This improves productivity and reduces scrap. The penetrating nature of ultrasonic cleaning removes residual polymer, mold release and outgas residue extending the mold life. It can remove residue from the cooling channels and vent lines improving polymer flow. In most cases, molds can be cleaned without disassembly, which significantly reduces the man-hours required for the cleaning process. |

| Ultrasonic cleaning is an immersion process that requires three components. The first is the tank to hold the liquid, the second is the chemistry in the tank and the third is the ultrasonic power supply and transducers.Branson offers systems in a number of configurations depending on your needs.Sizes range from tabletop tank and generator systems that are effective at cleaning inserts, core pins and small molds, to fully integrated wash/rinse/dry systems for larger molds. Most mold cleaning applications utilize powerful 25 kHz ultrasonics but Branson offers 40 kHz for more delicate molds. While the chemistry can vary based on the mold material and type of soil, most molds are cleaned in a buffered alkaline solution with a pH above 12. It is important that the cleaning agent contains a rust inhibitor to prevent flash rusting when the mold is removed from the cleaning solution.The mold is then rinsed by hand with cold water or immersed in a rinse tank.Drying is usually accomplished by blowing the mold off with compressed air and spraying it with a rust preventative.The typical wash time is less than 30 minutes and most molds do not need to be disassembled for processing. Branson has demonstration equipment available for inhouse testing at your facility. Contact your local Branson salesperson or the Danbury, CT facility for information and to schedule a trial. |
