As rotational moulding evolves to meet the demands of modern manufacturing, integrating technologies like RFID (Radio Frequency Identification) has become a vital innovation for product tracking, traceability, and production efficiency. ROTO-iD RFID Tags, specifically designed for rotational moulded products, make it possible to add smart tracking capabilities.
However, securely attaching these tags to moulded products requires a method that ensures durability, ease of application, and preservation of the product’s structural integrity. Spin welding emerges as the ideal solution, combining robust bonding with efficient installation.
The Spin Welding Process Explained
Spin welding is a specialized method of joining thermoplastic materials through frictional heat. It’s widely used in applications requiring durable, leak-proof seals. When it comes to securing RFID tags, the process is adapted to meet the specific needs of rotational moulding.
Here’s how spin welding works:
Drilling a Hole
A precisely measured hole (4mm diameter) is drilled into the rotationally moulded product to accommodate the ROTO-iD RFID tag’s center location pin. This step ensures the tag is positioned securely within the product’s surface.
Positioning the Tag
The ROTO-iD RFID tag, encased in a thermoplastic (PE) housing, is placed in the drilled hole.
Applying Rotation and Pressure
Using the ROTO-iD installation driver a spin welding machine (router) rotates the tag housing at high speed while applying pressure against the surface of the moulded product.
Generating Frictional Heat
The friction between the spinning housing and the product generates enough heat to melt the interface material.
Bonding and Sealing
The rotation stops, and the melted materials fuse together as they cool, forming a permanent bond. Crucially, the process completely seals the hole drilled into the product, restoring its structural and functional integrity.

Why Spin Welding is Ideal for RFID Integration
Spin welding brings several unique advantages, making it the best method for attaching ROTO-iD RFID Tags to rotationally moulded products:
Maintains Product Integrity
The drilling of a hole is a necessary step in RFID installation. However, thanks to spin welding, this potential weak point is completely sealed during the process. The result is a product that retains its structural integrity and functional properties, such as being watertight in applications like water storage tanks.
Durable and Long-Lasting Bond
Rotationally moulded products often endure harsh environments—extreme temperatures, UV exposure, and mechanical stress. Spin welding creates a bond that is strong enough to withstand these conditions, ensuring the RFID tag remains securely attached for the product’s entire lifespan.
Seamless Integration
Unlike adhesives or mechanical fasteners, spin welding does not leave visible joints or weak points and will not peel off over time. The RFID tag seamlessly integrates into the product, preserving its aesthetic and functional quality.
Cost and Time Efficiency
Spin welding is a quick process that requires no additional consumables like adhesives or screws. This makes it a cost-effective solution, particularly in high-volume production environments.
Compatibility with Rotational Moulding
Rotational moulding is used to produce hollow, durable plastic products. Spin welding aligns perfectly with this manufacturing method, offering a secure way to install RFID tags without compromising the product’s unique structure.
Securing the Future with Spin Welding and ROTO-iD
When paired with the ROTO-iD RFID solution, spin welding becomes a cornerstone of a smart, connected manufacturing process. Once installed, the RFID tags can be tracked through various post-moulding production stages using the RFID Reader and ROTO-iD software, providing valuable insights into production management, post moulding processes, and quality assurance.
The ability to seal the installation point completely ensures that the structural and functional properties of the product—be it a water storage tank, container, or industrial part—are preserved, making spin welding a win-win for manufacturers looking to enhance their offerings with RFID technology.
Conclusion
Spin welding transforms the challenge of RFID integration into a streamlined, effective process. By securely affixing ROTO-iD RFID Tags while sealing the installation point, this technique ensures that products remain durable, functional, and ready for the demands of modern manufacturing.
