Midwest Acoust-A-Fiber (MWAAF), which supplies automakers with high-temperature insulation and
noise-suppressing composite fiber materials for new vehicles, is employing a hybrid
RFID-based system at one of its two plants in Delaware, Ohio, in order to track raw materials as they enter the facility and are used in manufacturing. The factory also utilizes the system, provided by
Analytica, to track its finished products when they are placed in a storage area at the warehouse, and when they are shipped to customers.
Midwest Acoust-A-Fiber supplies its products to such companies as
General Motors,
Chrysler and
Ford Motor Co.. The firm custom-designs heat shields used in vehicular exhaust systems, catalytic converters and engine manifolds sustaining temperature ranges of up to 2,300 degrees Fahrenheit (1,260 degrees Celsius). The company also manufactures products to absorb noise coming from an engine, or under the body of a vehicle. At its two facilities, Midwest Acoust-A-Fiber employs 150 workers and operates 24 hours a day, five days a week, to meet the needs of its customers. Its annual revenues in 2007 was reported as topping $25 million.
Fiberglass and other raw materials arrive at the plant in rolls that are stored and then consumed during manufacturing. Finished products are stored in MWAAF's warehouse, then later sent to automotive manufacturers. With a growing operation in a limited amount of space, the company has developed a very tightly designed manufacturing facility with a growing number of assembly lines and production output. By employing bar codes with RFID, the firm can ensure it has the materials it needs on hand, without developing a space-consuming overstock.
Manually inputted records of shipment arrivals and departures provided MWAAF's managers with a solid understanding of the raw materials coming into the factory, as well as the shipments of finished products sent out. However, their knowledge of the plant's raw-material consumption and productivity rates was limited to a set of weekly or monthly reports. Three separate employee shifts work throughout each 24-hour period, making it difficult for workers to have a clear understanding of where materials and finished products were located, and what the quantity was.
"One of the main things we wanted," says Andrew Callahan, Midwest Acoust-A-Fiber's IT manager, "was to monitor our raw material, so that we had an accurate inventory count at any time."
Midwest Acoust-A-Fiber sought a solution that would take advantage of bar-coded labels already attached to rolls of raw material arriving from suppliers, as well as the bar-coded labels MWAAF places on boxes of its finished products for auto manufacturers. The bar-coding system alone would not allow the company to see where products were located within the facility, however, because the system knew only that the bar codes had been read, not where they had been read.

RFID Tag for use on Iron Holders
I would like to know if there is a system to control the mangement of my empty and full iron material holders with RFID over a factory of more than three sqaure miles. Can anybody give me a response please. We are losing iron holders because people are stealing them for melting. THANKS!

Need more information
There is no doubt that certain factory floor conditions can have an impact on a successful rfid implementations- the trick is identifying what the obstacles may be, what needs to be tracked and how to work around those conditions if possible. Ask Analytica for more detail about other work/analysis they have done in manufacturing. www.analytica-usa.com > I wanna know if there is a system to control my mangement of > my empty en full iron materialholders with rfid over a > factory of over tree sqaure miles.Please can anybody give > me a respond please about this because they begin to steel > the iron holders for meltin.THANKS

Tracking Iron Holders
It's definitely possible to track metal containers over long distances. There are a number of active RFID companies that have tags that can be mounted on metal. Three square miles is a lot of area, so you will need to invest in a significant number of readers to cover that area. The question is not whether it is feasible but rather will the cost be justified by the reduction in theft and improved visibility of containers and material.

But i also wanna know if i can work with passive tags on metal containers. Is this possible. BesT regards,

Is there the possibilty to work with passive tags. If this can what is the maximum range of the newest passive tags.Best regards,
