Cold foil printing, also known as cold foil stamping, is a modern method of printing metallic foil on a substrate in order to enhance the aesthetic of the final product. . Cold foil printing can be done two ways: the older dry lamination process common in the offset printing industry, or the newer, more versatile wet lamination process, which is dominant in the flexo label indus
Cold stamping, also known as press working, [1] is a manufacturing operation in which thermoplastics in sheet form are cold-formed using methods similar to those used in metalworking. [2] A precut thermoplastic sheet, possibly reinforced, is softened by heating to a temperature particular to the plastic in use.
The process is performed as follows: Sheet is adhered to a substrate with a heated roller. Laser traces desired dimensions of prototype. Laser cross hatches non-part area to facilitate waste removal. Platform with completed layer moves down out of the way. Fresh sheet of material is rolled into position.
Inorganic LED - Flexible LED is commonly made into 25, 50, 100 m, or even longer strips using a roll-to-roll process. A long neon LED tube is using such a long flexible strip and encapsulated with PVC or silicone diffusing encapsulation. Organic LED (OLED) - OLED for foldable phone screen is adopting roll-to-roll processing technology.
Rolled Annealed copper foil is produced through a rolling and annealing process, as described earlier. It offers good flexibility and is commonly used in flexible printed circuit boards (PCBs) and other applications where flexibility is required.
The physical properties, and sometimes chemical properties, of the materials need to be communicated to packaging engineers to aid in the design process. Suppliers publish data sheets and other technical communications that include the typical or average relevant physical properties and the test method these are based upon.
A simple cross-section schematic of the slot-die coating process. Slot-die coating is a coating technique for the application of solution, slurry, hot-melt, or extruded thin films onto typically flat substrates such as glass, metal, paper, fabric, plastic, or metal foils.
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
