Here are a few things to consider when buying an ultrasonic washer and none of it requires a degree in electronics engineering.<\/p>\n
1.\u00a0 SIZE MATTERS<\/strong>\u00a0\u2013 Pick the right tank size. Don\u2019t buy a unit that is too small for you largest critical parts, or a unit that can\u2019t handle the amount of parts (per load) you are putting into it.<\/p>\n If you think the unit you are buying is too small before you buy it, then it will definitely be too small once you start using it.<\/p>\n As a result, you won’t be able to see the great benefits of ultrasonic cleaning because you will put even more parts through then you ever imagined.<\/p>\n 2.\u00a0 FREQUENCY<\/strong>\u00a0\u2013 Make sure you have the best frequency for your application. For most applications, and by most I mean 95%+ in the world, 40 kHz is the frequency for you. Unless you have a rare specification calling out 25 kHz or are doing sub-micron cleaning of sensitive electronics requiring 68 kHz and above, then look no further than 40.<\/p>\n 3.\u00a0 POWER\u00a0\u2013 <\/strong>You need the right cleaning power for your application. Here is where it is best to discuss your application with a qualified ultrasonics company so you know what is required. Most equipment is outfitted with the correct ultrasonic power for the bulk of applications.<\/p>\n 4. CHEMISTRY\u00a0\u2013 <\/strong>Though most ultrasonic applications are cleaned in a water based solution, those solutions generally require some type of soap additive. Here again it is recommended to contact a qualified ultrasonics manufacturer<\/a> to discuss your specific application and get the right chemistry. There are soaps designed to remove oils and then separate out in the bath. Some applications do better with a surfactant, but chemistry is a blog post of its own.<\/p>\n 5. PROCESS<\/strong>\u00a0\u2013 The process involves the dwell time of the ultrasonics, the bath temperature, the chemistry concentration. Best to get a \u201cHow to Do Process Sheet\u201d from your favorite ultrasonic systems manufacturer.<\/p>\n
