In brief
The transfer-foil stack determines whether graphics release from the carrier and bond to the part under heat and pressure. Layer order and chemistry require part-specific trials.
The carrier supports printing and handling, release chemistry controls peel, graphic layers provide decoration, and bonding chemistry governs attachment to the part
The carrier supports printing and handling, release chemistry controls peel, graphic layers provide decoration, and bonding chemistry governs attachment to the part. Not every foil uses an identical number or order of layers; the supplier's construction controls.
Some transfer constructions need reverse artwork so the final viewed image reads correctly after transfer
Some transfer constructions need reverse artwork so the final viewed image reads correctly after transfer. The required orientation depends on layer order and viewing side. Confirm it with a cross-section diagram and a lettering sample before tooling.
LICHAO equipment supports heat transfer films for its reel-to-reel screen printer, supporting discussion of printed graphic layers
LICHAO equipment supports heat transfer films for its reel-to-reel screen printer, supporting discussion of printed graphic layers. Nissha describes heated roll or plate transfer of foil graphics onto a part. Qualify film printing and hot pressing as separate operations.
Record press temperature, pressure, dwell, peel timing, residue and incomplete transfer
Record press temperature, pressure, dwell, peel timing, residue and incomplete transfer. Test adhesion and durability across substrate lots. One successful-looking part does not prove a robust production window.
How do we start a trial?
Provide substrate, controlled artwork, material data, process flow and acceptance criteria. Use representative samples to confirm configuration and process window.
