This drum is either perforated (for spraying) or solid (for immersion). Its drum rotates vertically, moving the parts constantly, enabling it to wash complex design parts. Drum height and width can be varied to adjust cleaning speed and aggressiveness, based on the needs of an individual consumer.
Each piece is cleaned by a powerful spray-wash jet, effectively scrubbing the exterior surfaces. This is usually followed by an immersion and agitation process that flushes out blind holes, hollow parts, tubes, and the like, using an aqueous solution. A typical washer also rinses and dries, so parts are ready for use after exiting the machine.
A washer may also include additional processing stages, such as ultrasonic cleaning, rinsing, rust proofing/inhibiting, phosphating, sealing, lubricating, coating, etcetera. Stainless steel rotary drum parts washers are considered the most frequently recommended because they have a longer life.
Rotary drum parts washers have many advantages. These types of washers are highly efficient and ideal for high volume, continuous cleaning and drying of medium and small parts. They can be custom designed to fit parts as needed, and they clean with even precision, so the safety of a delicate part is not a concern. Even screw machine parts with exterior threads can be processed without damage. The washers yield a very thorough clean on not only metallic materials, but on all materials fed through it. It effectively removes oil and chips that may be present.
Another benefit of the rotary washer is its automatic controls. It can be fed automatically from another machine, such as a stamping, screw, die-cast, or grinding machine. This allows for an increase in productivity and a reduction in labor costs, as fewer operators are required to run the machine. Furthermore, the automatic design means that the operator’s physical output is much lower. The washer can be custom-designed to optimize the speed of productivity, to allow for cleanliness requirements, etc.
This equipment has a wide array of applications. It can most notably be used in the auto industry but can be applied anywhere that delicate parts need cleaning on a large scale.
