This equipment is used to removing corrosion, paint, ink, grease, oil, and dirt from workpieces. To get the quality product, you need to work on a clean surface. Parts washers are found in the second stage of powder coating, pre-treatment. The surfaces to be coated are washed with chemicals or detergents. Washing the parts is important as it strengthens the adhesions and thus leads to quality output.
Parts washers have an electric motor for driving a pump that circulates the chemicals through a nozzle. You should be very careful with the chemicals you put in the parts washer as some chemicals such as acetone immediately corrode the rubber or the entire body of your washer.
Like the other equipment, there are many parts washers that you can choose from depending on your budget and needs. They are distributed in several styles and sizes. Some of the reasons that dictate the type of parts washer to buy include the frequency of usage, cost of equipment, size of your unit, types of parts to be cleaned, and the type of grunge to be removed. In addition, you will have to consider whether you require a benchtop unit or a full-size stand alone washer. The type of chemicals you intend to use will dictate whether the body of your parts washer will be plastic or metallic.
Washers are available in various sizes ranging from a 5-gallon container to complex industrial-sized solvent washers. If you plan to perform surface prep work or powder coating, you need to acquire a parts washer. Having more than one parts washer is more advisable since you can have different cleaning solutions in each washer.
Workshop models: Some freestanding washers feature a drum of solvent located below a washing basin and a filter system. The cheaper models feature a basin filled with solvent. The most expensive units have a mechanism for heating the solvent, which yields better results. However, the heating unit in this equipment poses hazards of a fire breakout. Some of the states have restricted or outlawed solvent-based parts washers.
Biodiesel fuel is one of the greatest natural solvents. It is used to dissolve oil-based and grease deposits on surfaces. It functions well with all washers. Parts washers demand operators to be precaution while working. For safety purposes, it is advisable to use the parts washer in an open space especially when you are using the solvent in it as it gets dirty. Also, if the washer is filled with gasoline, kerosene, diesel fuel, or mineral spirits, it poses fire and vapor hazards.
Detergent-based benchtop cleaners: If you operate a small shop, you do not need a large and costly parts washer. You can opt for a small benchtop unit to save on costs and space. The design of this unit allows it to be assembled on a workbench. Though it is cheap, it is quite functional. Many benchtop washers use water and detergents only on the market today.
The best example of a benchtop unit is the Oil Eater. It is an affordable and functional parts washer. The cleaner has a compact and well-constructed body. It can be stored away from the workplace when not in use. An oil eater features a cleaning brush and a tube which are fixed to the pump. The detergent flows through the cleaning brush, making the cleaning process easier and eliminates the emission of a foul smell.
