Car washing is the manufacturer-recommended process of cleaning a vehicle. It can be performed manually, with equipment as simple as a bucket and a rag, although there are many products on the market to facilitate hand washing, spraying, scrubbing, waxing, and drying. These include pressure washers, natural or chemical cleaners and waxes, sponges, brushes, nozzles, and natural or synthetic cloths.
Hand washing of cars is still done commercially, but automated car washing technology has made the manual process, or at least most of the steps involved, all but obsolete, except for the die-hard hand washing fan.
Automated car washes may be completely automatic or may have attendants who perform certain steps in the process. They may be coin or credit card operated, manned by an attendant who monitors the machinery and equipment, or manned by multiple attendants who perform such steps as interior detailing and drying.
A car wash equipment manufacturer is a company that provides the equipment and material necessary for various kinds of commercial and sometimes industrial car washes. When starting a car wash business, many businesses purchase used car wash equipment. There are many different kinds of car wash systems; some work without employees and some operate with many. Automated car washes have gained significant popularity in recent years. They are very common and come in two different varieties: touchless and cloth friction. Touchless car washes use high-powered water pressure sprayers to clean cars, which either move around the parked car or are stationary through which the car passes. Only the water and cleaning agent come in contact with the car, which prevents scratching and marking the car's finish. The alternative, cloth friction, uses soft yet powerful cloth to clean the car, which are large, rotating brushes that use soap to scrub the car exterior clean. Both forms of auto car washes use sensors called eyes that trigger a digital control system to enable the washing sequence and adjust to the car's size. Near the end of auto car washes is usually a drying station, where high-pressure compressors blow air over the surface of the vehicle, drying it before exiting the car wash.
A centrifuge system is designed to separate different elements within a particular substance by way of a high speed rotation known as centrifugal force. The simplest and perhaps crudest demonstration of centrifugal force can be witnessed in a laundry washer or dryer that is typically found in a residential home. As the washer spins, dirt is separated from the clothing.
Centrifuges traditionally are made out of plastic, metal alloy, and metal, and are powered by an electric motor that uses a rotor. The substances placed within a centrifuge can be either liquid or solid, and include those found in the medical field, such as blood, as well as industrial solutions, products, and fuels. In some cases, centrifuges are also used to create or refine certain food products. In general, centrifuges work by creating a temporary but very strong gravitational well that separates elements based on their density. In most cases, the process must be a continual one that is synced to a particular cycle of varying speeds; if the cycle is interrupted, the separation will not be complete, and may damage the equipment. There are numerous types of centrifuges designed for specific environments, including laboratory centrifuges, industrial centrifuges, and decanter centrifuges. However, the two principal types of centrifuges are referred to as preparative and analytical. An analytical centrifuge is traditionally used for research applications where the components of a particular substance are being identified, while a preparative centrifuge is used to separate particles from a given slurry or liquid.
Machinery rebuilders are service companies that disassemble, clean, repair and/or replace machine components in order to increase their service life. While rebuilding is considered to be an old-fashioned term in some industries, having been replaced in common use by the term "remanufacturing," other industries such as the railroad industry have maintained the term in common usage.
Paint finishing equipment is the broad category of tools and machines that includes all devices used in the paint finishing process. By definition, the paint finishing process is the application of coats of paint or a finish to a surface. There are many different types of paints and finishes that vary in characteristics such as color, hardness, durability, sheen and other attributes. Finishes can be applied both for visual appeal and function and the methods used to apply them differ greatly as well.
Tube forming machines refer to various types of equipment that are used in order to form tubing, which is the process of altering tubing into complex shapes. A tube is defined as a long and thin hollow cylinder that is most commonly used to either convey a fluid or gas, or to function as a passage. Typically cylindrical, tubes can also be formed into square or rectangular shapes as well.
Tube forming differs from tube fabrication, which is the manufacturing of tubing, and is considered to be a secondary process to tube fabrication. The machines that perform tube forming processes must be able to maintain a high level of accuracy due to the complexity of the various shapes required. As a result, tube forming machines are generally either dedicated machines or automated manufacturing cells. While dedicated machines are built for a specific job and thus, cannot accommodate any design changes, automated manufacturing cells are able to provide high production rates as well as the ability to be versatile in design. Some examples of applications and industries that utilize tube forming machinery include: marine, for use in exhaust products, heat exchangers, piping systems and more; automotive, to be used for structural components, coolant systems, exhaust manifolds and more; industrial manufacturing, for applications such as various automation equipment and tubing assemblies; and medical, for use in complex components such as glass capillary tubes, epidural needles and arthroscopic drivers.
