Compared to other thermal processes, the UV process has
4 merits below.
■Instant curing |
■Pollution-free and safety |
●Time saving : |
The curing time only lasts 0.1~a
few seconds |
●Space saving : |
The process itself is compact |
●Cost saving : |
The system can be design into
a proper scale according to the disposal volume. |
|
●Improved working
environment : |
In principle, the
system is powered by electricity and no solvent
are in use, so the system will not cause some
problems of the air-pollution and odor emission. |
●Simplified
equipments : |
Solvent disposal
devices and anti-pollution facilities are not
needed. |
|
■Low temperature curing |
■Improved quality |
●Suitable for heat-sensitive
materials : |
The materials can be chosen widely. |
●Energy saving : |
Energy is just consumed in the
necessary process at the necessary time. |
|
●Reinforced
strength (high-intensity) |
●Flawless and
odorless :
The finished work is perfect in uniformity and
has no paints and any bad smell of ink with it. |
●Metallic luster
gives the product a feeling of quality. |
●Solvent resistance,
chemical resistance and pollution resistance are
improved greatly. |

The realization of any each of processes: adhering, peeling,
curing or drying relies on the chemical bonding of the organic
compounds caused by UV irradiation.
It is necessary to find proper processes for different products
and materials. Being as an example, the different kinds of
light sources used in UV curing process are listed below.
