How RNA Automation Automated Fastener Replenishment with Fabory Logic

RNA Automation, based in Birmingham, UK, specialises in automated feeding systems, robotics and visual inspection. Before introducing Fabory Logic, fastener replenishment relied on manual stock checks, purchasing approval and manually created purchase orders.

Fabory introduced RFID-tagged smart bins and a Weight Scale Cabinet to automate stock monitoring and replenishment. Within three months, RNA reported zero stockouts and reduced the time spent on stock checks and purchase-order administration from four to five hours per week to less than 30 minutes.

The challenge: manual replenishment and purchasing administration

Before Fabory Logic was implemented, the purchasing process for fasteners at RNA followed a traditional model. A merchandiser carried out an on-site stock check, recommendations were reviewed and approved by the purchasing department and a purchase order was then created and sent manually.

This process created communication delays and bottlenecks in replenishment. It also required the purchasing team to spend several hours each week on repetitive administrative work.

Missed stock counts or delayed approvals could lead to stockouts, urgent orders and production disruption.

How the manual process worked

1 Manual stock check A merchandiser manually checked fastener stock on site.

2 Purchasing review Recommendations were reviewed and approved by the purchasing department.

3 Manual purchase order A purchase order was created and sent manually.

Two technologies, one automated replenishment process

Fabory implemented two inventory technologies at RNA: RFID-tagged smart bins and a Weight Scale Cabinet. Both reduce the need for manual stock checks and support automatic replenishment when predefined stock thresholds are reached.

RFID inventory management RFID smart bins When stock levels drop below the set threshold, the RFID-tagged smart bins generate automatic notifications to Fabory so replenishment can be arranged.

Real-time consumption monitoring Weight Scale Cabinet The Weight Scale Cabinet tracks material consumption in real time. When the weight falls below a predefined minimum, a replenishment order is automatically triggered.

Results within three months

RNA reported measurable improvements within three months of implementing the new system.

Before installation, the company experienced five to six stockouts per month. After installation, RNA reported zero stockouts during the three-month results period.

The purchasing team had previously spent four to five hours per week on stock checks and purchase-order administration. After implementation, this was reduced to less than 30 minutes per week spent monitoring the automated system.

The case reports that this change recovered more than 200 working hours.

Better visibility for purchasing

The automated system also provides live inventory data that supports purchasing forecasts.

With stock monitoring and replenishment handled automatically, the purchasing team can spend less time on repetitive inventory administration and more time on strategic sourcing.

The reduction in manual ordering steps also helps reduce the opportunity for errors within the replenishment process.

“Fabory UK’s new fastening solutions are an excellent addition to our operations. The solutions align seamlessly with RNA Automation’s business model, which is focused on delivering innovative automation solutions.”

The result: less administration and greater stock visibility

By combining RFID smart bins with weight-based inventory monitoring, RNA moved from a manual replenishment process to a more automated approach.

Within three months, RNA reported zero stockouts and reduced weekly inventory administration to less than 30 minutes. The case also reports more than 200 working hours recovered.

Live inventory data supports purchasing forecasts, while automated replenishment reduces the need for manual stock checks and purchase-order creation.
