Explosion Proof Ultrasonic Cleaner Options
Explosion-proof ultrasonic cleaners must be used when cleaning tasks call for the use of volatile solvents to achieve the desired results. See examples below. When low flash point flammable solvents are involved in an ultrasonic cleaning operation, a number of precautions are called for in addition to using an explosion-proof ultrasonic cleaner. This is because using these solvents creates what the NEC and NFPA term a hazardous location.
A flash point is the temperature at which a particular organic compound gives off sufficient vapor to ignite in air when given an ignition source. In view of this, selection of an ultrasonic cleaner must take into account that not only do volatile solvents evaporate, but the heat generated by the ultrasonic cleaning process accelerates solvent evaporation and vapor generation.… Read the rest
Sonic Cleaning Solves 3D Printing Mold Support Challenge
3D printing, also called fused deposition modeling and fused filament fabrication, has revolutionized and lowered the cost of traditional molding techniques such as the lost wax process. By using two moldable thermoplastic formulations such as ABS for the part itself and PLA for removable mold supports 3-D printing is capable of quickly producing highly complex configurations.
A key to the efficiency of the process is fast, safe removal of the PLA mold support without risking damage to the ABS part. An ultrasonic cleaner is proven far faster, safer and more effective than water sprays or manual scrubbing.
3-D Printing in Brief
Computer aided design files for components are programmed into the 3D printer which uses thermoplastic filaments to create components by successively building up extremely thin layers of plastic. The ABS filament ends up as the product; the PLA filament, deposited at the same time, serves as a support for … Read the rest
