Switching power supply unit. Screen printing on metal
The substrate is a brushed metal panel printed with functional identification markings for an industrial power supply unit. The print required precise multi-point registration across the full panel surface to ensure terminal labels, voltage indicators and warning text aligned exactly with the physical connectors and cutouts on the finished assembly. The ink system used was formulated for metal adhesion and durability,.
The project involved the production of 100 identical metal power supply units for different types of systems -a component requiring precise screen printing using special scratch resistant inks on a metal substrate with strict scratch and durability requirements. Made in 2 days with 0 defects.
Process:
One print pass was executed on an ATMA TP 45 flat-bed screen printing press. Yango cleaning system was used in between passes to maintain screen integrity, dust free print and better print quality. A custom inline production line ensured consistent substrate handling and throughput precision throughout the run. Each interface symbols, was proof-checked before batch approval.
