Coating & Dispensing Methods
Coating in manufacturing requires selection of coating equipment (coaters, dispensers) in accordance with conditions such as the target (workpiece, substrate), material (adhesive, coating material), and purpose (adhesion, surface processing, functionalization).
This section describes the following equipment and systems used for coating.
- Roll CoatingRoll coaters have a structure consisting of multiple rollers and are suitable for coating sheets or films. Various system types are available for different coating thicknesses.
- Robot PaintingPainting robots are typically used for painting or coating car bodies. Multi-axis robots and stage control have become increasingly sophisticated.
- Spray CoatingSpray coaters are generally used for spray coating the surfaces of flat sheets such as panels or glass.
- Spin CoatingSpin coaters are used to create a uniform thin film through the centrifugal force of rotation. This coating equipment is typically used for semiconductor wafers or optical media.
- DispensingDispensers are sophisticated automatic coating systems that creates a bead of adhesive or sealant, or apply a precise coating through a small quantity of adhesive or cream solder.
- Inkjet CoatingThese mechanisms are based on high-resolution on-demand printing technology. They allow precision pattern coating directly from digital data without the need to make plates.
- Screen PrintingScreen printing can be used for a wide variety of target materials, surfaces, and shapes. The use of a high-resolution screen mask allows precise pattern coating.
