OMRON TM12 Cobot

From manual glue removal to automated precision finishing

Topcustom, an Italian manufacturer of custom Ocritech bathroom sinks, needed a more consistent way to finish a wide range of product geometries. Operators were manually removing acrylic glue bands and deburring varied contours, which required skilled labor, introduced variability, and extended delivery timelines during peak product mix.

To improve the process, Topcustom implemented an OMRON TM12 collaborative robot with 1300 mm reach. Using CAD/CAM data from each customer’s 3D model, the system generates toolpaths for glue residue removal and edge refinement, with adjustments retained for repeat production. Integrated safety scanners allow supervised operation by pausing motion when personnel enter the work zone.

The automated cell helped increase output by 15% to more than 800 sinks per week while supporting a consistent two-week order-to-delivery window. It also reduced rework, freed operators from repetitive manual finishing, and created a foundation for future digital scheduling and traceability.

Results at a glance:

15% increase in finished sink throughput now over 800 units per week
Order to delivery window reduced to two weeks from a prior three week upper bound
Consistent removal of 1.5–3 mm acrylic glue band with repeatable edge quality
Dual side coverage from a single TM12 reach eliminates repositioning delay
Product code to path linkage enables scalable digital traceability
Labor redeployed from manual edge work to supervision and variant integration
Safety scanner integration protects personnel without cycle penalty

Tailored automation for precision finishing

Precision finishing can be challenging in high-mix production environments with demanding hygiene and surface-quality requirements. OMRON worked closely with Topcustom to develop a robotic cell that combines collaborative robots, integrated safety, and CAD/CAM data flow.

The solution supports more predictable finishing quality while freeing skilled staff for higher-value work. If your team is exploring ways to reduce manual bottlenecks or improve custom production workflows, we can help identify an approach that fits your process.
