Extrusion Technology 40mm Series Q & A

+ What makes the Robotunits 40 mm extrusion system different from other aluminum extrusion systems?
The Robotunits 40 mm series stands out with its universal 14 mm T-slot design, ensuring full compatibility across all profiles and accessories in the system. Its patented fastening technology allows for strong, vibration-safe, and play-free connections without drilling or milling. Each extrusion features a tubular honeycomb internal structure, offering outstanding torsional rigidity and strength-to-weight ratio. This results in lightweight yet durable assemblies with connection strength comparable to welded joints.
 
+ What extrusion sizes and configurations are available, and can they be mixed?
The 40 mm series includes multiple profile options such as 16x40, 40x40, 40x80, 80x80, and 40x120, covering a broad range of framing needs from light-duty to heavy-duty applications. Standard lengths reach up to 6 meters, and the uniform slot design enables compatibility with other Robotunits series like the 50 mm line. This modular flexibility makes it easy to mix profiles and expand or modify structures as needs change.
+ How are the extrusions connected, and can assemblies be reused or adjusted?
Robotunits extrusions use drop-in nuts and engineered fasteners that securely fit into the 14 mm T-slot, creating robust, precisely aligned connections without machining. Assemblies can be easily repositioned, adjusted, or reused without damaging the profiles, making them ideal for modular setups or applications requiring frequent changes. The fastening technology delivers strength equivalent to welded joints while maintaining full adjustability and reusability.
 
+ What are the mechanical limits and structural capabilities of the 40 mm series?
The honeycomb core structure of the 40 mm profiles delivers excellent torsional stiffness and load-bearing performance. Fasteners and connectors can withstand tensile loads up to 4 tons, depending on configuration. The system is suitable for machinery framing, guarding, conveyors, and automation equipment. For high-load or vibration-sensitive designs, engineers can reference Robotunits structural data or request application support to confirm load ratings and deflection limits. 
 
 
+ What are the practical benefits—availability, finish, compatibility, and support services?
All Robotunits extrusions come anodized for corrosion resistance and are available pre-threaded or cut to length for easy assembly. The standardized slot and hardware design simplify inventory and ensure full cross-compatibility across the Robotunits system. Authorized distributors such as Valin offer cut-to-length, kitting, and turnkey assembly services to streamline project implementation. The modular design allows users to expand, reconfigure, and reuse components, offering a long-lasting, cost-effective, and scalable framing solution.
