Extrusion Technology 50mm Series from Robotunits

Extrusion Technology 50mm Series from RobotunitsThe 50 mm Series from Robotunits is a premium-grade modular aluminum extrusion system engineered for demanding automation and machine-construction applications. Featuring a robust 14 mm uniform T-slot and a tubular honeycomb interior for exceptional torsional and load resistance, this extrusion family supports heavy-duty frames, robot bases, machine guards, workstations and enclosures. All profiles are anodized for corrosion resistance and immediate use—no additional surface finishing required—and the system offers full cross-compatibility with Robotunits’ broader modular platform, enabling re-use, reconfiguration and long-term adaptability.

The main areas of application are mechanical engineering, protective equipment, assembly cells, and manual workstations.

Extrusion Technology 50mm Series Q & A

+ What features distinguish the 50 mm extrusion series from other extrusion systems?
The 50 mm series provides greater rigidity and load capacity than smaller systems such as the 40 mm series—making it ideal for machine frames, guarding, and heavy industrial structures. Each profile features a universal 14 mm T-slot for full cross-compatibility with all Robotunits components. A tubular honeycomb core improves torsional stiffness and vibration resistance, supporting long-term durability in demanding environments.
 
+ What sizes and profile options are available?
The 50 mm extrusion family includes profiles such as 50×50, 50×100, 50×200, 100×100, and 100×200 mm, with standard stock lengths up to 6 meters. All profiles share the same slot geometry, allowing seamless integration with 40 mm series extrusions and accessories. The modular system supports mix-and-match design, making it easy to build frames tailored to specific load and span requirements.
+ How are connections made, and can assemblies be reconfigured?
Connections use drop-in nuts and specialized fasteners that fit the 14 mm T-slot—no drilling or welding required. This method ensures quick assembly and allows parts to be reused or repositioned without damaging the profiles. The connection design maintains vibration resistance and long-term precision alignment, even after multiple reassemblies.
 
+ What are the mechanical limits and ideal applications?
The 50 mm series delivers excellent torsional rigidity and load-bearing strength thanks to its internal honeycomb structure. It’s suitable for high-load frameworks, machine bases, and dynamic assemblies. For extreme vibration or high-impact environments, engineering review and load testing are recommended to confirm performance limits. While highly durable, it’s not a one-for-one replacement for heavy welded steel in extreme shock applications. 
 
 
+ What support and customization options are available?
Robotunits provides anodized profiles, tapped ends, and complete accessory compatibility across its modular system. Customers benefit from cut-to-length, kitting, and pre-assembly services available through distributors such as Valin. The modular design enables quick expansion and cost-efficient reconfiguration, reducing downtime and long-term ownership costs.
