RFID controlled window component production at Fenestra



by Steve Barclay

Fenestra was in process of completely updating and automating their two window component production lines, namely the production lines for wooden window frames and sashes. One of the most important requirements towards the production lines was the capability to customize each individual component according to a specific customer order. This requirement means that each component needs to be identified at each machine tool in order to determine the machining configurations (e.g. in case of a saw, this could correspond to the length of the component) for each manufacturing step.

Similar production lines have been previously implemented by using barcode technology. In Fenestra’s case the barcode technology had however severe drawbacks, namely: (i) the high amount of dust present in the wood industry environment disturbs the barcode readers lowering significantly the barcode read rates and (ii) the window components are painted and the applied paint would cover the barcodes, rendering them useless.

Vilant Systems developed and supplied an RFID based production control system for Fenestra’s window component production lines. In the system each individual component is tagged with a HF tag which enables their identification before each production machine. The manufacturing specifications for each individual product are then specified for each component at each individual machine tool based on this identification. The RFID system has very high read rate and is capable working also after the window components have been painted.

The system enables fully automated window frame and sash production lines allowing each component to be customized as per customer order instead of “fixed model” production batches. The system includes over 50 readers. As a true milestone in RFID credibility the system produces a phenomenal read rate of over 99,999% with 100 000 daily reads for over a year now.
