As manufacturing automation advances, businesses are placing higher demands on identification technologies with greater environmental adaptability. RFID high-temperature-resistant labels, as the name suggests, are radio frequency identification (RFID) tags that can operate stably in high-temperature environments. They can withstand temperatures as high as 150°C or even 300°C and are widely used in industries such as electronics manufacturing, metal heat treatment, automotive painting, and medical sterilisation. These labels serve as a crucial tool for achieving intelligent traceability and process control.
This article will focus on five common application scenarios for RFID high-temperature resistant tags and analyse their key roles in each industry.
-
High-temperature identification in SMT electronics manufacturing
During the SMT assembly production process, electronic components undergo high-temperature reflow soldering and wave soldering processes, with temperatures reaching up to 260°C. Ordinary tags would melt or fail under such conditions.
Advantages of RFID high-temperature resistant tags in this scenario:
Attached to PCB trays or product containers for full-process automatic identification
Can withstand multiple passes through high-temperature furnaces while maintaining stable and readable tag information
Integrated with MES systems to enable automated product traceability
-
Metal Manufacturing and Heat Treatment Process Tracking
Steel, aluminium alloys, and mechanical parts often require high-temperature quenching, tempering, hot pressing, and other heat treatment processes during manufacturing.
RFID high-temperature resistant label application highlights:
Installed on trays, workpiece hoists, or material frames inside heat treatment furnaces
Accurately marks batch information, furnace entry/exit times, and operators
Ceramic or metal-encapsulated UHF tags can withstand temperatures above 250°C
-
Paint curing and assembly traceability in automotive manufacturing
During automotive painting and curing processes, vehicle bodies must pass through high-temperature curing ovens, typically operating at temperatures between 180°C and 200°C.
Tag usage:
Installed on the chassis, fixtures, or conveying equipment
Real-time reading of vehicle identification numbers and painting process status
Resistant to paint mist and corrosion-resistant structural encapsulation, enhancing service life
-
High-temperature sterilisation management in the medical industry
Hospital surgical instruments and testing equipment often require high-temperature steam sterilisation (121°C to 134°C). Manual record-keeping is prone to errors and lacks traceability.
Application value of RFID high-temperature resistant labels:
Attached to the surface of medical devices or sterilisation racks
Records each sterilisation time, operator, and frequency
Integrates with hospital HIS or asset management systems for automatic archiving
-
Sintering and Tracking in the Glass and Ceramics Industry
Glass and ceramics manufacturing requires high-temperature sintering at temperatures ranging from 700°C to 1000°C. Traditional barcodes are completely inapplicable.
RFID label solutions:
Ceramic or high-temperature-resistant metal casing, which can be directly embedded into trays or moulds
Suitable for long-cycle, high-frequency firing environments
Automatically records product type, firing time, and process status
-
Other Potential Application Areas
Industry Application Points
Aerospace Manufacturing Identification of engine parts during thermal processing
Food Processing High-temperature sterilisation equipment recording
Energy Industry Identification and management of furnace internal facilities
Mould Manufacturing Mould temperature control, cleaning, and inventory recording
These fields are also gradually adopting RFID high-temperature resistant tags to achieve digital asset management and process standardisation.
How to choose the appropriate RFID high-temperature resistant tag?
When selecting a tag, consider:
Temperature Rating: 150°C / 200°C / 250°C / 300°C
Reading Range Requirements: Near-field reading (HF) or long-range reading (UHF)
Installation Method: Adhesive, screws, straps, or embedded
Encapsulation Material: Ceramic, PPS, PEEK, PI
Usage Scenario Cycle: Whether frequently exposed to high temperatures
Summary: The broad prospects for high-temperature RFID labels
As a powerful tool for solving tracking issues in extreme conditions, high-temperature RFID labels have become an important tool for multiple industries to improve automation levels and reduce management risks. In the future, with the development of the Internet of Things and AI factories, their application scope will become even more widespread.
