There are two basic components to virtually every manufacturing process: motors and the devices that control them. Typically, control devices are large and operate on the same voltage used to power the motors. This results in large motor-control centers that may not provide maximum reliability.
Safety is always a concern in a textile mill because of potential fire hazards. When Avondale Mills, based in Graniteville, SC, constructed a 217,000-sq.-ft. addition at its Horse Creek, SC, plant, the facility installed enclosed luminaires to both improve light and help eliminate lighting-related fire hazards.
As the number of manufacturing jobs declines in the U.S., so does the traditional image of the factory worker. Lean times have made today's worker both more competitive and technically sophisticated. A company can only be as good as its employees. But since 1980, the number of employees in manufacturing jobs has dwindled - significantly.
Soy-based engine oil does not readily boil off and resists heat degradation. In tests, it caused a significant drop in hazardous air emissions, compared with petroleum-based oil. The 2002 Farm Bill signed by President Bush encourages the use of biobased products, including those made from soybeans.
Lead Wastewater Treatment Plant Mechanic, Tom May (atop engine) inspects one of the six Waukesha lean-burn engines that provide power for the Pima County Wastewater Treatment Plant in Tucson, AZ. The engines run exclusively on sewage effluent gas. Using sewage effluent gas to fuel engines and generators, operators of the Pima County Wastewater Treatment Plant in Tucson, AZ, save an average of $30,000 a month in outside energy costs, reduce environmental pollution by fueling with gases that otherwise would be flared off to the atmosphere, and reduce the use of non-renewable natural gas resources.
RCM is not complicated, but requires groundwork and the understanding that it is an ongoing process, not a one-time project. Most writers on the subject of Reliability-Centered Maintenance (RCM) emphasize that it includes a systematic approach to determining what must be done to ensure the reliability and availability of physical assets in a production setting.
The Abengoa Bioenergy Corp. ethanol fuel plant in York, NE, is one of three U.S. facilities formerly operated by Wichita-based High Plains Corp. that produces 85 million gallons of ethanol a year. It earns $42,000,000 annually and uses more than 19 million bushels of local grain. That type of demand requires that production run at the height of efficiency.
Under the Federal Clean Air Act (CAA), many manufacturing operations have become subject to stricter local regulations regarding both VOC (volatile organic compound) and HAP (hazardous air pollutant) emissions. The CAA singles out 188 air pollutants that are of special concern, many of which are used in everyday production and/or manufacturing atmospheres.
The auto supplier's die-casting facility in Niles, IL, is nearing plant-wide completion of a 5S strategy that has both bonded the workforce and helped keep the unit competitive through tough times. Tom Dolack, director of engineering; a Metaldyne worker operates one of the facility's 40 die-cast machines; Tom Fisher, general manager; and a completed automatic-transmission valve body is cleaned and inspected.
Both the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) require facilities to perform routine inspections. These requirements were established to protect the environment from damage and workers from injuries. Routine inspections are a good way to uncover problems, and inspection forms are one of the things that an OSHA or EPA compliance officer will ask to see during an inspection.
Ixion Ceramics, Inc., a Chattanooga, TN-based subsidiary of Ixion Technologies, Inc., designs and manufactures microcircuit "packaging" for telecommunications, military, aerospace and other applications. It makes precision-engineered ceramics and metals that begin as slurries and, when shaped and dried, form tapes and pastes that are, in turn, used to create electronic circuits or screen-printed dielectric layers.
An OSHA area director and, in an exclusive interview, Assistant Secretary of Labor John Henshaw give their views on OSHA inspections, working with the business community, and the satisfaction they derive from helping make workplaces safer. On December 29, 1970, President Richard Nixon signed the Occupational Safety and Health Act.
Automatic lubricators can be installed on most applications that require greasing maintenance. Here, a worker adjusts the lubricator on a honing machine for bearing manufacture. Nearly 90% of all bearings are lubricated with grease and 80% of all bearing failures are lubrication-related.
How do you find mechanical and electrical parts for foreign-made machines here in the U.S.? Maintenance and plant engineers were asking this question at Viking Polymers, a maker of plastic polymers, when they recently needed replacement parts for a specialized, German-built machine at its Jamestown, NC, facility.
Conserving energy on the factory floor cuts costs, reduces energy dependency and helps the environment. A lighting retrofit is an effective way to do that. The U.S. business/industrial community is the best place to start cutting greenhouse-gas emissions. Why? Seventy percent of all electricity is consumed by this sector.
One of the most important parts of a cordless tool system is the corded part: the battery charger. Not only does the charger deliver power to the tools, it affects their economy, efficiency and performance. It's a complex relationship that is often misunderstood. Cordless-tool technology was developed for NASA.
At Dacotah Cement's Rapid City, SD, facility, business starts at a nearby quarry where piano-sized blocks of limestone are blasted from the earth. The blocks are crushed into gravel-sized pieces and blended with other raw materials. Next, the mix is further pulverized in ball mills, where turning steel cylinders filled with thousands of steel balls crush it into powder.
Metrics and lean manufacturing helped turn this family-owned business from a fast-growing, but disorganized player into a world-class leader in the booming market for vinyl replacement windows and doors. Republic's award-winning facility (upper left); Kevin Heylin, vice president of manufacturing (center); and Senthil Rajamanickam, director of window operations and maintenance (above).
Dock-seal fire damage caused by truck-trailer marker lights. Burned loading dock-seal head pads or head pads damaged with burn holes can be found on many docks at which truck/trailers stay parked with the engine running for as little as 20 minutes. Frequency of the burn holes - and fires, in some cases - spiked in the late 1990s, baffling investigators, who first thought they were caused by bare trailer-light bulbs touching seal material.
Weldwood of Canada, Ltd., is a leading producer of plywood and lumber products. To meet ever-increasing demand, the company, a subsidiary of International Paper Co., recently made key investments in new technology to increase plant capacity at its facilities in western Canada. Among the tools used were new computerized maintenance management systems (CMMS) that have been installed at six of its plants in British Columbia and Alberta.
