Many manufacturers and factories have happily used solvent cleaning solutions for many decades. However, new environmental research has uncovered that many of these solvent solutions are not only bad for the environment; they can also be bad for human users. This means that many new regulations are calling for more earth-friendly cleaning solutions for parts.
This can pose a difficulty with some parts cleaners, because many aqueous cleaning methods simply are not as powerful as solvent cleaners. Luckily, parts washing manufacturers have spent much time researching ways to make aqueous solutions more effective. These new methods use scientifically-backed cleaning methods, including bioclean systems, nano particles, specifically formulated bacteria, and engineered cleaning methods that bind dirt particles to soap particles. With these new methods, it is possible to avoid harsh solvent cleaners while still maintaining clean parts and complying with aqueous-based regulations.
Not all cleaning methods will work with all parts. For the best insight into what style of cleaning method you will need, speaking with a parts cleaning manufacturer is the best option. A dedicated parts-cleaning company will be able to help you uncover the best cleaning method that will comply with your region's cleaning regulations. Most companies will have a wide range of solutions to choose from that may even benefit other areas of your business and budget. Systems including ultrasonic, bio-based, and simple soap aqueous cleaners can all meet the increased environmental regulations required in many modern factories.
Parts cleaners clean, degrease and sometimes dry mass quantities of large or small industrial parts in preparation for surface treatment, assembly or distribution. Chemicals, oils, burrs and other residue from the fabrication process must be removed from the surface of parts before they can undergo surface finishing. Coatings such as electroplating and zinc cannot be effectively applied over dirt or grease.
Industrial washers, an example of a parts cleaner, may be designed as multi-stage processes, deburring, cleaning, drying, surface treating and even powder coating all in one application. Other parts washing machinery may be as simple as a single-stage immersion aqueous parts washing tub. Parts cleaners use water, aqueous chemical solutions, ultrasonic blasts and agitation to clean part surfaces; sometimes non-aqueous methods such as acoustic cleaning, vapor cleaning, vibration cleaning and laser ablation are used. Many parts cleaners use aqueous parts washing to remove surface oils, although non-aqueous methods are sometimes used when aqueous cleaning is impossible. The two main methods aqueous parts cleaners use are spray washing and immersion washing. Immersion washing, which is also known as agitation, immerses parts in a hot organic or water-based chemical solvent in a mesh basket that turns, rotates and shakes dirt off of the parts. Immersion washers can be as simple as a tub in which parts are placed or removed, or they can be a series of tubs with different washing solvents and automated arms.Until very recently, most aqueous parts washing solvents have been chemical-based, but the recent emergence in environmental and worker safety concerns and regulations have made the use of organic solvents more common. Ultrasonic cleaning is an innovative precision cleaning method that requires much smaller solvent concentrations than traditional washing; this cuts down on harmful and expensive waste. Tiny air blasts burst against parts' surfaces, cleaning in crevices that other washing techniques can't reach. Automotive parts washers often use ultrasonic cleaning to reduce the risk of malfunction due to part contamination. Surgical, dental and electronics parts washing often involve ultrasonic cleaning. In industries that depend on exactness and precision, contamination by oil, grease or dirt can mean the difference between smoothly operating machinery and loss of thousands of dollars or even lives. Parts cleaners are invaluable in industrial manufacturing, not only because they provide thorough cleaning solutions, but because they also reduce labor costs.
