Parts washers embody one of the last steps in the parts manufacturing process; they are designed for the precision cleaning, degreasing equipment, and drying of mass quantities of small or large parts in preparation for surface treatment and distribution. Newly machined, forged, or fabricated products are usually coated in oils, chemicals, burrs, abrasive dust, debris, paint, and other residue left over from the fabrication process; finishing coatings内蒙古快3-首页 such as zinc and electroplating are not effective if they are applied on a dirty surface. Parts washers solve these problems by cleaning them.
Industrial parts washers are used extensively to clean carbon, grease, metal chips, cutting fluids, or other contaminants off various metal pieces. Their application ranges from small metal pieces, such as nuts, fasteners, and screws to large metallic bodies, including automotive assemblies, rail bearings, diesel engine blocks, and even wind turbine gear boxes.
Aside from industrial manufacturers, the electronics, automotive, and medical industries frequently use industrial cleaning equipment. They clean equipment, furniture, and technologies that require painting, powder coatings, zinc coatings, lubricants, electroplating, and other surface treatments that would not be possible without thorough parts washing.

The History of Parts Washers
Parts cleaning technology was first developed in the mid-twentieth century for use in automotive transmission and engine repair shops. There, parts washers improved upon the previous “soak tanks,” which were simply vats filled with detergent and water, in which mechanics placed parts to soak for hours. Parts cleaning equipment and systems made the process of rinsing of soiled parts much faster, easier, and more effective.
Initially, solvents were composed of mineral spirits, naphtha, or organic trichloroethylene, xylenes, and benzene. The system of cleaning was simple; a low amp, flame-tight electric liquid pump skimmed the dirty metal piece with solvent until it was cleaned in drum washers or rotary drum parts washers.
In the late 1960’s, manufacturers began refining their methods in order to lessen environmental impact and improve safety. At that time, they transitioned from using degreasers like gasoline, diesel fuel, and kerosene, to slightly gentler cleaner and degreaser types, like vapor degreaser and chlorinated solvents. In the 80’s, chlorinated solvents for parts cleaning were banned. After that, aqueous-based cleaning systems, which were first developed in 1971 by Gary Minkin, became the industry standard. The prominence of aqueous solutions and systems ushered in many improvements, like the use of hydraulic impact pressure, which improved cleaning power.
Today, thanks to a few key changes, many parts cleaning equipment and systems are environmentally-friendly. In the past, water-based cleaning solutions were not as effective as chemical cleaning. Today's technology has changed that; the newest forms of parts washers use biomatic parts. They use a heater washer containing a PH neutral cleaning solution combined with a microbe colony that breaks down grease, oil, and other contaminants to give the parts a cleaning that is highly effective and environmentally safe. Another key improvement of modern parts washing has been this integration of CNC programming. CNC programming manages the whole process, saving labor and time.
内蒙古快3-首页The future of parts washing is bright; likely, as the years go on, engineers will find ways to make the cleaning systems and processes even more efficient, thorough, environmentally-friendly, and cost-effective.
内蒙古快3-首页Parts cleaning equipment typically consists of a water heater, a filtration system, pumps, scrubbers, brushes and nozzles, and a cabinet.
内蒙古快3-首页Water heaters can be gas, electric or steam powered. The filtration system collects waste and debris generated by the cleaning process. Pumps increase the pressure of sprayers, and scrubbers and brushes help dislodge contaminants from parts. Hot water, detergents, solvents, vapors, acids and alkaline solutions, some synthetic and some natural, are used to break down contaminants and remove them from parts. Cabinets (also called enclosures or housings) are often made of stainless steel, though some cabinets also feature glass and plastic components.
When designing parts washers and systems, manufacturers have many design options. For example, some washers are fully automated and controlled by CNC machines to adjust settings, while some require manual loading. The parts being washed can be front or back loaded, and they can be washed in a basket, tray, rack system, by a robotic arm, a rotary table or conveyor belt. Most part washers are aqueous, meaning they use water and a water-based chemical or natural solvent in which they boil, blast or soak the dirty parts until they have been cleaned. Some solvents have additives, called inhibitors, that impede harmful chemical reactions between an aqueous cleaner and a non-ferrous metal substrate.
Because there are as many types of unfinished parts to wash as there are fields of industrial manufacturing, an industrial parts washer manufacturer will typically offer custom designs. These parts cleaners may be as simple as a stand-alone basket immersion parts washer内蒙古快3-首页, or they may be as complex as a five-step deburring, aqueous tumbling, rinsing, drying and paint coating machine. Innovative industrial technology makes it possible to combine many parts of the finishing process into one specialized machine.
内蒙古快3-首页Broadly, washers either are solvent-or aqueous-based:
Solvent Parts Washer
Solvent-based metal parts washing systems clean metal pieces by dissolving away dirt and scum. The first parts cleaning equipment was only solvent-based and required gallons of petroleum-based solvent; later, more varieties of solvent came. Today, solvent based parts cleaners are no longer as popular as they once were. This is because solvents are often not very eco-friendly, and it’s harder to find solvents that meet environmental safety standards.
Aqueous Part Washer
Aqueous cleaners use pH-neutral or water-based solutions to break down and clean dirt from metal part surfaces. To increase efficiency, manufacturers do sometimes introduce semi-aqueous cleaning solutions, which have a small amount of solvents, into these systems. The principle is to use detergent and water in combination with mechanical and heat energy to clean; they either use jet spray or power wash approach.
In addition to these categorizations, parts washer systems can be broken down by their level of automation, from manual to semi-automatic, and, most commonly, fully automatic.
Manual Cleaning Washer
Characteristically, this drum or vat style cleaning system is most suitable for low volume cleaning. Ideally, you can follow a manual cleaning routine if your part cleaning processes take about 30 to 40 minutes of time every day. If your processes involve many small parts, then also this method is fruitful.
Semi-automatic parts washers feature some automated stages but are not fully automatic. Usually, they require manual loading and unloading, or they work in conjunction with a separate conveyor system.
Automated Cleaning Washer
These washers are suitable for operations where parts are cleaned over 45 minutes a day. Switching to an automated process, as a general rule, could result in significant time and cost savings. You can find a list of companies manufacturing these washers on IQS Directory.
Some modern washers are classified based on their functionality:
Cabinet-Style Parts Washer
As the name suggests, cabinet washers are in the shape of cabinets. Cabinet style washers use a combined action of heated aqueous spray and mechanical energy to wash the grease or carbon from metal piece surface. Cabinet-style washers are equipped either with a fixed or retracting turntable; the turntable grips and rotates the metal parts during the cleaning process.
High-Pressure Spray Washer
Most commonly, these are cabinet-style washers. They operate like common dishwashers found in homes and professional kitchens. However, the sprayer features are more in-depth than those of a standard dishwasher. A high pressure spray machine, or industrial pressure spray machine, employs a high-pressure water jet from different angles to clean machine parts. The spray machine's rotation feature ensures that a maximum number of surface areas are cleaned thoroughly.In general, a powerful stream of water that is rich in aqueous-based chemicals is used for washing the parts. That's why these devices fall under the aqueous part washer umbrella. These aqueous-based chemicals could be a combination of detergent, hot water, and alkaline chemicals. When high pressure meets mild to high temperature, there is no match for cleaning quality.
Ultrasonic washers are relatively new to the industry. These cleaners are composed in a cleaning bath, in which the parts are hit by a force of ultrasonic energy. The energy causes the solvent to vibrate and then cavitate, or form bubbles. These bubbles then implode, cleaning surfaces using these tiny underwater air blasts and solvents. In addition, ultrasonic cleaning equipment causes contaminants and parts to vibrate and move, making contaminants dislodge more easily. Ultrasonic cleaning can be the most suitable method for removing pollutants from pipes, holes and unattainable smaller machine areas.
内蒙古快3-首页Finally, some other parts washer varieties include green washers, spray washers, rotary drum washers, drum washers, conveyor parts washers, immersion/agitating washers, small parts washers, and automotive part washers.
The newest forms of parts washers use biomatic parts. This mixes the best of biology and other scientific research to benefit the environment. The parts can be placed into a heater washer containing a PH neutral solution combined with a microbe colony. The microbes can then break down grease, oil, and other contaminants to give the parts a cleaning that is highly effective and environmentally safe.
After the materials are used by the microbes, the hydrocarbons are converted into carbon dioxide and water. The water is then filtered and used again. Oxygen is pumped into the solution to keep the microbes healthy and happy. When this form of system is used, not only is it beneficial for the environment, but it can be reused almost indefinitely, making the entire process cost-effective and extremely friendly to the environment.
Spray washers, which are quite common, are built with an enclosed conveyer belt that moves parts through a spraying water cleaning machine. Usually, the spray portion of the spray washer comes from one or more nozzles. They do not necessarily wash products with the same intensity as high pressure spray washers.
Rotary Drum Washer
Rotary drum washers are neither immersion nor spray washers. Instead, they tumble smaller parts through a rotating drum that washes, rinses and dries the parts. It has a spiral conveyer on the inner wall that moves parts in a circling motion in order to clean all sides. Some washers are designed specifically around the product they are washing. You can find companies who are producing these washers on IQS Directory.
Drum washers are used to wash larger drums, pails and barrels in industrial settings that hold and store different chemicals and materials, such as paint, inks, grease and adhesives. Each time they are emptied or change the chemical, material or product they are housing, drums must be thoroughly cleaned. Drum washers must be able to clean the interior and exterior of these containers since both come become dirty very easily. Spray washers and rotary washers are the best solutions in this case since the nozzles can reach the drum interiors. They are then air or heat dried.

Conveyor Parts Washer
Unlike cabinet-style washers that use a turntable to hold the metal piece, conveyor washers use a conveyor to move parts continuously throughout the washing process. They either use a simple belt conveyor or an overhead conveyor. If you'd like to learn more about this type of part washer, you can visit this site.
Immersion Washer/Immersion Agitation Washer
Also known as agitating parts washers, these vat-style cleaners contain parts by submerging them deep into a wide bath. They are the most advanced washers, using a combined action of agitation, spray, or ultrasound and a cleaning fluid to remove contaminants.
Small Part Washer
Typically, after the parts are underwater and coated in a solvent, mechanical energy creates a vibrating and mixing action via impellers or paddles. Both of these immersion methods are effective in cleaning parts ranging from small to large. In addition, these cleaners are mounted in a way so that the high-pressure spray can clean different areas of the machine parts within a moment. Whether the cleaning arrangement is indoors or outdoors, this method can be ideal for both the areas. This system is more effective than ultrasonic washing.
Finally, small parts washers, either rotary or immersion washers, are designed specifically to handle large amounts of small parts such as fasteners and screws.
Automotive Part Washer
Automotive parts washers clean vehicle engines, transmissions, pneumatic parts and hydraulic parts in hot water solutions and ultrasonic cleaning tubs. Not only do they clean newly manufactured car parts, but used parts that have become dirty due to road grime, dirt and grease as well.
Advantages of Parts Washers
There are many advantages to parts washing. These include:
- Low maintenance costs
- Low power requirements
- Energy efficiency
- Ease of Use
- Diversity of method choice

Proper Care for Parts Washers
For metal parts washers to work optimally, there are numbers of things that you have to be mindful about.
内蒙古快3-首页Here are some expert tips for running your parts washers efficiently and for many years.
1. Avoid storage of to-be-cleaned metal pieces: Parts that need cleaning should be directly moved from the production line to the cleaning resource. Stored parts that have oil and grease on them accumulate more dirt during storage, putting extra pressure on parts cleaning machinery, which results in longer cycle times, affecting operation costs. This also affects the maintenance and repair costs of the parts cleaning equipment.
2. Burring complicates cleaning–avoid it: Metal parts that have burrs complicate the cleaning process, making it difficult for the cleaning detergent or solvent to reach and penetrate the area around the burr. Moreover, sometimes, burrs come off while washing, making work harder for the filtration and cleaning systems. Removing burrs内蒙古快3-首页 before cleaning can make the process easier.
3. Don't put too many parts in a batch: If you fill the basket to it's limit, it leaves less space for cleaning action, and this may lead to unsatisfactory cleaning. This may decrease output, but it will improve cleanliness significantly because it allows more solvent to access the parts.
4. Choose the right cleansing solution: If contaminants on the metal parts are oil-based, like cutting fluids or coolers, a hydrocarbon cleaning process gives optimum results. If contaminants are water-based, like grinding or lapping compounds, aqueous parts washers perform well. This small consideration can affect cleanliness levels and cycle times.
5. Make sure your operators are properly dressed: In manufacturing environments, humans unknowingly transfer contaminants, such as oils and strands of hair, which complicate the running of metal parts washers. For that reason, we recommend that the operators wear hairnets, lint-free gloves, work coats, and body suits while handling the washers. This clothing will also protect them from potential harm from corrosive wash materials or chemicals.
Because you will be using your parts washer with workers around, it’s always a good idea to make sure that your wash system is OSHA compliant. We also generally recommend asking for ISO and/or ASME certification. These certifications offer general quality assurance. From there, standard requirements are dependent largely on your application. For example, a parts washer used to wash military products needs to meet Mil-Specs.
