Most extrusion systems feature fasteners and other hardware that loosen over time, opening these structures up to vibration. To avoid these harmful effects, machine designers tend to reach for steel when assembling a robotic frame. Although steel does have its benefits, it can easily drive up costs – especially where handling is concerned. It also doesn’t offer the flexibility of other material systems
Our aluminum extrusions, on the other hand, feature fasteners, standard screws and centering insertion pieces that keep the screw from loosening when tightened. This interaction between the extrusions and fasteners achieves high tensile strength – up to 4 tons per fastener – and avoids loosening of hardware and misalignment due to potential vibration.
