High-Temp Applications in Automotive Manufacturing

Updated: Feb 11

RFID expands past supply chain to more demanding applications where RFIDs tag will face high temperatures like those found in automotive manufacturing processes.


The Xerafy Micro X-II series are RFID metal tags that allow the implementation of the RFID tags directly on the asset early in the production process to provide management with tracking information as specific to better identify where the product is, where this product is stored and detect bottlenecks within the manufacturing process.


A properly designed RFID system can greatly improve efficiencies, control costs and streamline overall production processes. Additional benefits of applying the RFID tag at the source level is to assist in inventory control, quality, and returns and counterfeiting prevention. Many applications exist where a label cannot be mounted on a surface. The current challenge from customers is for a tag that has superior performance on metal and can survive high temperatures, pressures, and harsh environments of demanding applications.


The complex process of manufacturing an automobile involves many measures and steps to ensure that what starts out as a bare chassis becomes a complete automobile able to be driven out of the factory. Ensuring that all stages of assembly are completed correctly and in a timely manner is critical.


Therefore, it is critical that each chassis has a mechanism that allows tracking at any point during the manufacturing process. In addition, the chassis goes through a paint process and a high-heat oven to rapidly cure the paint before moving to the next stage. Currently chassis are tagged with a barcode label often accompanied with a paper “traveler”. For the barcode label, physical and mechanical handling of the chassis during the manufacturing process may damage the label to the point it cannot be scanned, or the label may fall off completely. Particularly during the paint process, the label will be painted over and therefore completely unreadable. For the paper “traveler”, more often than none they are simply lost along the way due to handling.


An automatic mechanism that allows a seamless and contact-less method of tracking work in process (WIP) of an automobile, including identification of the vehicle VIN number cross-referenced with build-sheets ensures that the proper parts and even paint colors are used. Likewise, when the chassis reaches the paint booth, the mechanism must not only survive the paint process but also the baking process involving a heavy-duty oven reaching between 43°C/110°F to 60°C/140°F during a very short period of time.
