About high-speed, pre-processing moulds and ultrasonic casting sand removal equipment

With the cooperation of a vacuum equipment manufacturer, the Company has succeeded in developing a high-speed vacuum pre-treatment and ultrasonic cleaning machine.Two engine blocks (550X300X150mm) are vacuum pre-treated and ultrasonically cleaned simultaneously.Precision sand removal.Ultrasonic waves are synchronous oscillation on both sides of one engine block, 25 KHz fundamental frequency to 275 KHz simultaneous multiple waves, 2400 W x 2 units of 4800 W. Two engine blocks are 9600 W. Ultrasonic power density is 2 W/cm2. 2 engine blocks are inserted simultaneously, after vacuum pre-treatment,Ultrasonic cleaning with cavitation enhancement system.

We do not call it vacuum ultrasonic cleaning.This is because in a vacuum, no matter how powerful ultrasonic waves are irradiated, the speed at which cavities (groups of microvacuum nuclei) collapse is too slow and the expected cleaning power cannot be achieved.

Insert the engine block and start the cleaning process with a two-handed start.The cycle of vacuum pre-treatment => ultrasonic cleaning (casting sand removal) => in-situ is fast, taking less than 75 seconds for two engine blocks. Vacuum pre-treatment and ultrasonic cleaning systems are the best means of overcoming the effects of air, but their time-consuming nature has been a drawback.We would like to inform our customers that with the successful commercialisation of this high-speed, vacuum pre-treatment system, we have been able to overcome the most significant drawback.

The method of immersing the object to be cleaned in a liquid and then depressurising it to remove air from the object is to create a liquid containing a lot of gases around the object to be cleaned, which defeats the purpose of a vacuum.The meaning of a vacuum is to fill every corner of the object to be cleaned with a degassed liquid.A comparison can be made between immersing fibrous materials in water and then vacuuming them and immersing air-free fibrous materials in a degassed liquid after pre-vacuum pretreatment. High-speed, vacuum pre-treatment ultrasonic cleaners are expected to be used not only for casting sand removal, but also for a wide range of cleaning and deburring applications where air is difficult to remove.

Cast sand removal technology is integral to the development of ultrasonic enhancement technology.

Blue Star R&D has developed a new powerful transducer dedicated to ultrasonic deburring.This vibrating element can also be used for casting sand removal, and is capable of ultrasonic casting sand removal from a wide range of castings.If you have any problems, please contact Blue Star R&D.
