Digitally validated, AI-optimized bowl feeders designed for reproducible, high-performance feeding.
RNA’s Digital Bowl Feeders represent the next generation of feeding technology — a truly unique innovation on a global scale. Using AI and 3D Geometric Deep Learning, RNA can create a digital twin of the feeding system, allowing it to be simulated, tested, and optimized virtually before the physical system is built.
Before any hardware is manufactured, the sorting solution is tested, verified, and approved using Digital Feeder™ simulation. Even at an early concept stage, this allows RNA to determine whether a component can be fed reliably, providing confidence that the final solution will perform as intended in real operation and can be reproduced consistently across builds.
Many RNA bowl feeders are already digitized and can be tailored precisely to the application. The RNA Digital Bowl Feeder features a sorting track (custom tooling specific to the material), which can be CNC-milled or 3D-printed. This tooling is developed after detailed simulation and assessment of the bulk material.
Using multiphysics simulation combined with 3D Deep Learning AI, the optimal tooling geometry is calculated with high precision. This ensures close alignment between the digital simulation of the feeding process and the actual, reproducible behaviour of the components in operation, resulting in stable, predictable transfer from bulk material to the linear outfeed.
RNA’s digital capabilities are applied not only to advanced systems, but also to conventional feeding technologies — combining proven mechanical design with modern digital intelligence to deliver reliable, reproducible bowl feeder solutions.

RNA 3D machined bowl feeders are custom-designed and manufactured using advanced 3D machining techniques. RNA focuses on the CAD/CAM-supported production of polyamide and aluminium bowl feeders for very small and small parts. With RNA digital solutions, all 3D machined bowl feeders can be reproduced and fully simulated.
RNA 3D printed bowl feeders are designed and produced using additive manufacturing techniques, allowing for rapid customisation and full reproducibility. They are flexible and can be quickly changed over for different part shapes and sizes, making them ideal for industries that require high flexibility, such as electronics and small parts manufacturing.
