Most sheet metal parts, including the body, formed by a machine that presses a piece of sheet metal between the two parts of the mold (die). Because the metal is formed by only one die tends to wrinkles, cracks, or tears, died a few commonly used to form each component.Bak sub-assembly is created automatically. Once rolled into a shape of a drum, hand welded. Welding is then smoothed and drum placed on expander, which runs into the tub in final form. A bottom is then welded to the drum, and the weld is also smoothed. not visible unless you open the cabinet machine, enameling iron with porcelain coating is commonly used. Whirlpool is the exception, using plastic instead of metal enameling to sink outside.Many other parts are plastic, too. Manufacturer of plastic raw receives from where they made the inside a little ant-sized pieces, using them for engine components that do not bear the weight and / or require a very good corrosion resistance. These sections include pumps, guard bathtub (which prevents you from being thrown out of the clothes spinning tub into the sink cabinet or area), and agitator.Transmission is usually made of cast aluminum, which arrives from the manufacturer in ingot-20 pound slab of aluminum. Usually remelted scrap parts and reused. Hose, controls (timers, switches, etc.), and the motor is purchased in the form of prefabricated from other manufacturers.ManufacturingProcessThe process of creation is divided into fabrication (making part), sub-assembly (putting parts together to make the components), and assembly (putting parts together to form the final product). The fabrication process includes different procedures, each specific to a particular type of raw material-sheet, metal plastic aluminum, or. After the constituent parts have been made, they are assembled; major sub-assemblies, or components, including transmissions, pumps, spin the tub and wash, ring balance, and painted parts. Finally, sub-assemblies are put together in the shell of the washing machine, which is then complete.Manufacture* 1 Most sheet metal parts formed with a machine called the press. The name is pretty descriptive, as the engine is really pressing (or squeezing) a piece of sheet metal between the two parts of the mold called a die. This metal will take the form of space between the sides of the metal mold. Because the metal is formed by only one die tends to wrinkles, cracks, or tears, died a few commonly used to form each component. Where possible, the metal is fed directly from the coil to the press. If this is not possible, a metal that is cut lengthwise and manually (or, with parts of the larger such as cabinets, automatically) placed into the mold.* 2 plastic material formed in the injection molding machine, metal mold with one or more cavities in the shape of the desired part. Once heated to the melting point, the plastic is forced into a mold under high pressure. Furthermore, water is passed through the mold to cool and strengthen parts. Mold is then opened and the ejector pin pushed out by. When you see a piece of plastic, you can see a small circle created by this pin.* 3 Section Aluminum transmission formed into a rough shape in die cast machine, which works like an injection molding except that it does not use pressure. It
Most of the key components of transmission, motor, cracked stored under the agitator assembly. The ring is a ring weighted balance that makes the washing machine from moving during operation. liquid metals are mechanically scooped into molds and cooled. Casting rough next then given a final shape with a variety of machines that drill holes, shave the remaining metal of the critical surfaces, or cutting of metal parts.Sub-assemblies* 4 transmission is assembled manually by workers who bolt, snap, or press (tight fit) some of shafts and gears together. Workers then add the amount of oil meter and bolt the unit together.* 5 pumps are assembled automatically. Robot put the seal on the impeller and cover and body, and the pump seal. Some manufacturers use heat and vibration of others (which generates heat) as a sealant.* 6 The tub is made in the press, and sub-assembly is created automatically. Once rolled into a shape of a drum, hand welded. Welding is then smoothed and drum placed on a unit called expander, which runs into the tub in final form. A bottom is then welded to the drum, and the weld is also smoothed. If the tub is polished stainless steel so it will not snag clothing. If the tub is dipped in a solution is called soil mantle and heated to about 1600 degrees until the coating is hardened. If the tub will not be visible (the sink), the unit is done. If the tub will look (like spin), coat finish is applied following the same procedure used to coat the ground, this coat gives the final form of color like white or blue.* 7 ring great weight balance that stabilizes the washing machine. Outer structure is plastic, with a ring of metal melted into the plastic for strength. Cement is added and the balance just right. This ring, which weighs more than twenty pounds, keep the machines from "walking" or moving while in use.* Manufacturers washer 8 using one process multiple paintings. One manufacturer has been using prepainted steel by steel producers. Although less expensive, type of steel does not offer the best rust protection for cut edges are not painted. Other companies treat their parts with a variety of chemicals to clean and ready them before applying the paint. In some cases, the paint comes in a powder with a consistency like flour. Mixed with air and given an electrical charge, the powder is sprayed on the part that hangs from the overhead conveyor and opposite charge and powder that will attract each other. After spraying, the conveyor moves to the oven that melts the paint, when the part cools, the paint finish.Assembly* 9 The process begins with the installation of the transmission on the ring balance. Transmission is set on a racing pads sink, wash basin sitting on a conveyor. Other bearing (lower bearing), brake assemblies, and the pulley hard put at the end of transmission. Furthermore, the rotating mechanism called the pivot dome and ran legs on the assembly to hold all the pieces together.* 10 Using a hydraulically operated mechanism, and then lift the assembly workers, called modules, to the bottom of the washer. The springs were added to hold the module and base together. A seal is added, like spin the transmission bolted to the inside of the sink, and the plastic cover snaps into place. A plastic hub, a stirrer attached to the transmission, which is bolted to the output end of the transmission shaft. Then the agitators who snapped to the hub.* 11 The pump and mounting bracket are now jumping into the motor, which is equipped with a shield to protect against potential leaks. The assembly is bolted to the bottom of the washing machine and connected to the transmission module with belts and hoses.* 12 Furthermore, the hinge cover attached to the lid and the top. The top of the washing machine bolted to the cabinet with a hinge for easy maintenance. A mixing valve to control the mix of hot and cold shot to the back of the cabinet. Graphic panels, which provide the words and pictures to explain the controls, mounted on the control panel, the inherent self-control from the rear. Cable, connected as a single unit, called a harness. Harness is clipped to the control connector on one end and the other end is passed through the hole in the top to be fitted to the motor. Because of their large size and weight, cabinet assembly is then placed in a washing machine by a robot.* 13 cabinet is bolted to the bottom, and the controls are snapped together with the mating connector on the module and motor. The drain hose is pulled through the cabinet and a section called goose neck is added. This section is what gives shape hose hanger so it will accelerate down the drain. After the test, the front panel bolted, and an information package and accessories added.* 14 units completed are packed automatically. A machine open cardboard box, a flat for shipping, and drop it on top of the washing machine. Upper and lower lids folded and glued together. Then the machine applies pressure at the top and bottom of the box to make sure the glue sets properly. After the glue has set, place the machine webbing at the top of the crate to add strength to lift truck transportation (units made from the top to reduce the risk of damage).Quality ControlAll parts purchased from outside producers who place inspected before use, and most of the sub-assemblies are also examined. For example, all transmissions are automatically tested for operation, noise vibration, and. All pumps are leak tested using air, automatically if they have automatic and manual assembly if it is manual. All parts painted visually examined for defects. Daily samples were placed in the tub of detergent, bleach, and steam for corrosion testing. Once it has been completely assembled, the machine filled with water and tested for defects noise, vibration, and visual, as well as functional and control mechanisms. After packaging, some units are put through a severe test to simulate transport conditions to test Cartoning process.Byproducts / wasteThe rest of the rest of the sheet metal are sold to metal recycling centers, and the rest of remelted aluminum for use. The rest of the plastic is ground into smaller pieces and used back in the non-visible part because the color can not be kept consistent. The paint is not used (in powder form) reclaimed and reused automatically. Of chemical processes such as paint reacted to form hazardous waste and disposed of safely.FutureAs motorcycles became cheaper and more durable, it would be economical to offer washing machines driven directly by the motor and not the belt, make washing machines more flexible and less noisy. Another trend is likely to be a gradual shift over load washing machines with front-load washing machines, which, because they require less water, meet government restrictions on water use. In Japan, the washing machine is being tested that cleans with bubbles instead of agitators. Using a computer, the machine "senses" how dirty every load of clothes and then generates bubble activities necessary to eliminate the amount of dirt. It is called "fuzzy logic" because it mimics human logic closer than a regular computer. If successful, this machine will be available elsewhere. Further in the future people can use washing machines clean by using ultrasonic-sound waves that vibrate at frequencies of more than
Although today most home washing machines in the United States is the top-loading, is likely to be gradually replaced by a front-load washing machine. Because they require less water, front-load washing machines meet government restrictions on water use. Also, in Japan being tested washer that cleans the bubble rather than an agitator. Using a computer, the machine "senses" how dirty every load of clothes and then generate bubbles acfivity necessary to eliminate the amount of dirt. 20,000 cycles per second, can not be distinguished by the human ear
