In the past year, aircraft manufacturers have been increasing RFID tag solutions to meet the needs of Airbus and Boeing. Both companies have set a schedule for supplier aircraft parts marking. To meet these needs, Brady, an industrial and security printing technology company, has released the second generation of aviation RFID solutions to provide complete RFID printing and encoding solutions for UHF RFID system customers.
As part of the solution, the company's software, RFID printers, handheld readers and tags are primarily sold to European companies serving Airbus. Recently, these products began to be sold to North American suppliers. For example: Rockwell Collins has signed a contract to use RFID tag solutions in its own business. The printing and coding system from Brady will generate the tags needed to identify and track Rockwell Collins' flying components wirelessly.
Brady manufactures 11 different styles of ATA Spec 2000 compliant RFID tags, nine of which can be printed on rolls. Wesley Columbia, Brady's global strategy and marketing manager, said it is the world's largest line of aerospace labeling products. He said the company's goal is to meet a variety of needs, including tracking of fuel lines, life jackets, oxygen generators and more.
Aero RFID solution is a product of the Brady SmartID business unit that provides RFID printing, encoding and reading solutions. Columbia said Brady has a long history of labeling in the aerospace industry. "Given the Brady's materials science and RFID expertise, RFID tags are coming in very well." The company's dual-record tag stores historical data related to maintenance. Authorized parties can access this information via RFID tags. The company also introduced a multi-record memory tag designed to store aircraft part life and parts maintenance history.
In addition to air tags designed for safety equipment, the company also offers a variety of flexible alloy metal tags and rigid metal tags. Brady also created a chemically resistant surface on its label, which means that the fluid and kerosene fuel will not damage the printed information on the label.
Brady's aviation RFID solution also includes a desktop software for managing the printing and encoding of labels as well as an RFID printer encoder jointly developed with Honeywell for printing and encoding labels. Brady also offers a handheld reader (Nordic ID or Zebra MC9190-Z card reader), as well as a software for collecting read data.
So far, Columbia said most of its customers are early adopters of RFID and are all major Airbus providers. In recent months, the client base has expanded to North America to meet similar Boeing requirements.
Rockwell Collins intends to use the Brady solution to turn metal tags on and off to identify aircraft components. These labels can be used on flat and curved items. Rockwell Collins will use these tags in their existing manufacturing workflow system.
Some of Brady's other customers include fuel lines, electronics, passenger seats, oxygen generators and life jackets.
Some companies also intend to use RFID tags to collect and store oxygen generator maintenance history and expiration management.
Because life-saving equipment must be regularly inspected and maintained, RFID technology will provide airlines with a quick way to identify the location, condition, safety, and useful life of safety equipment without touching the equipment. In some cases, the label needs to be attached to the metal can body, while in other cases the label needs to be placed on the cylinder shell.
In addition, aerospace RFID tags are used to track life jackets and other safety equipment. Without RFID technology, removing the lifejacket with a barcode label takes more than an hour for the ID number. However, using RFID technology, this process can be reduced to within a few minutes.
"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."
Gravity Die Casting
Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.
The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.
GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.
There are three key stages in the process.
- The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
- Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
- Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.
Advantages
- Good dimensional accuracy
- Smoother cast surface finish than sand casting
- Improved mechanical properties compared to sand casting
- Thinner walls can be cast compared to sand casting
- Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
- Steel pins and inserts can be cast in to the part
- Faster production times compared to other processes.
- Once the tolling is proven, the product quality is very repeatable.
- Outsourced Tooling setup costs can be lower than sand casting.
