Solution:
Tags are applied directly to the surface of metal tools. Their high-temperature resistance ensures continued readability in extreme heat environments, enabling comprehensive inbound/outbound management and “no-tool-left-behind” control within high-temperature zones.
Typical Case Study: A steel mill’s hot rolling workshop managed over 300 high-temperature tools in an operating environment of 120–180°C; the tags remained fully functional and stable after three years of continuous use.
Power Equipment Inspection Management
Typical Environments: Boiler Rooms, Substations, Generator Rooms
Managed Assets:
- High-temperature pipelines and valves
- Pressure vessel equipment
- Power generation assets
- Inspection tools
Solution:
Tags are affixed to equipment nameplates or critical components. Inspection personnel use handheld scanners to read the tags, automatically recording inspection timestamps and equipment status to establish comprehensive equipment maintenance records.
Results:

- Fully traceable equipment maintenance history
- Rapid localization of anomalous equipment
- 60% increase in inspection efficiency
Pressure Vessel Asset Management
Typical Environments: Petrochemical Plants, Chemical Plants, Pharmaceutical Plants
Managed Assets:
- High-pressure gas cylinders and steel bottles
- Pressure vessel bodies
- Specialized equipment accessories
- Container-specific tools
Solution:
Tags are affixed to the container surface to record information such as container ID, inspection dates, filling records, and operating units. This enables full lifecycle management of pressure vessels and provides automated reminders for mandatory inspections.
Compliance:
Meets the traceability management requirements for pressure vessels stipulated by the *Law of the People’s Republic of China on Safety of Special Equipment*.
Metal Container/Pallet Management
Typical Environments: Warehousing & Logistics, Production Workshops
Managed Assets:
- Metal turnover boxes
- Steel pallets
- Metal storage racks
- Logistics containers
Solution:
Tags are mounted on the bottom or sides of containers. Identification is performed via portal gates or handheld scanners, enabling comprehensive management of container borrowing/returning, circulation tracking, and inventory auditing.
Results:
- Container turnover rate increased by 40%
- Container loss rate reduced by 90%
- Automated inventory tracking; efficiency improved by 95%

FAQ
Q1: How is the 230°C high-temperature resistance of the tag achieved?
A: It is achieved by utilizing a housing made of specialized engineering materials, a high-temperature-resistant antenna, and an industrial-grade chip, all of which have undergone rigorous high-temperature aging tests. In practical applications, the tag operates stably over extended periods in environments reaching 200°C.
Q2: How much external force can the tag withstand after being attached?
A: It utilizes 3M VHB industrial adhesive, featuring a shear strength of >1.5 MPa and capable of withstanding a tensile force exceeding 100 kg. It will not detach under normal usage conditions; however, for applications requiring even stronger fixation, a bolt-mounting option is available.
Q3: Does the reading distance decrease in high-temperature environments?
A: There will be a slight impact, but the reading distance remains greater than 1 meter. In tests conducted at 180°C, the reading distance still reached 1.2 m.
Q4: Can the tags be reused?
A: If attached using the adhesive backing method, the adhesive surface will be damaged upon removal, so reuse is not recommended. If attached using the bolt-mounting method, the tags can be reused.
Q5: Can these tags be used in food-grade or medical-grade applications?
A: The tag housing material complies with RoHS environmental standards; however, it has not undergone specific food-grade or medical-grade certification. If you have such requirements, please inform us in advance, and we can provide relevant material certifications or a customized solution.
Q6: What are the MOQ and pricing details?
A: Please contact our customer service team to inquire about the MOQ, as pricing varies based on order volume tiers. We will provide an optimized quotation tailored to your specific quantity requirements.
Q7: What is the lead time for delivery?
A: Standard products (non-customized): 2–3 weeks; Custom encoding/printing: 3–4 weeks; Special customizations: 4–6 weeks. Lead times for large-volume orders will be negotiated separately.
Q8: Are samples available for testing?
A: Yes! We can provide samples for testing and validation purposes (a nominal fee to cover sample costs may apply). We highly recommend conducting preliminary tests in your actual operating environment to ensure the tags fully meet your requirements before placing a bulk order.
