The development of UVLED light curing technology in recent years has become more and more mature, and it has also 

been widely used in various industries. Compared with traditional mercury lamps, UVLED light curing has the advantages of 

fast curing, energy saving and environmental protection, and is more popular with customers. And UVLED is a cold light 

source, suitable for the curing of heat-sensitive materials, and has a wider range of applications than mercury lamps.

      In the printing industry, many printing materials are plastic, paper, film, etc. This type of material requires the curing 

equipment not to be too hot to avoid damaging the material itself, but also requires the curing equipment to have a 

certain amount of energy to quickly complete the UV ink curing. In this regard, as a cold light source curing device, UVLED 

curing machine is more suitable for UV ink curing than mercury lamps. Next, Height-LED uses an example of label printing 

technology that is more sensitive to heat.

      Heat shrinkable film label is a kind of film label printed on plastic film or plastic tube with special ink. During the 

labeling process, when heated (about 70℃), the shrinkable label will quickly follow the outer contour of the container. 

Shrink, close to the surface of the container, heat shrinkable film labels mainly include shrink sleeve labels and shrink 

wrap labels. The shrink sleeve label is a cylindrical label made by printing after heat shrinking as the base material. It is 

easy to use and is very suitable for special-shaped containers.

      The production of heat-shrinkable film labels requires high process technology. For ordinary water-based and solvent-based 

inks, if the drying temperature is too high, the material will heat shrink; if the temperature is too low, the ink will not be dried 

thoroughly. The process is quite complicated and the rejection rate is high. The UVLED curing machine can make the UV ink under 

the action of ultraviolet energy, make the polymer material form a network cross-link in an instant, the ink cures quickly, and has 

no effect on the temperature of the printing material. The unique cold curing system is very suitable for the label of heat-sensitive 

materials. Production. So that UV light curing technology can solve the problem of heat shrinkable film labels.

      Moreover, the UVLED curing machine has a pure ultraviolet light output, no heat radiation, infrared lamp pollution, and no 

heavy metals, which are harmful substances. Compared with mercury lamps, it is more green and environmentally friendly. At 

the same time, the UVLED curing machine saves energy consumption, and the energy consumption of the UVLED curing 

machine is only mercury lamps. About 10% of the lamp, the service life is about 20 times that of the mercury lamp. This is why 

in recent years, more and more customers have changed the mercury lamp production line to the UVLED curing production line.

      As a professional manufacturer of UVLED curing equipment, Shenzhen Height-LED has rich curing experience and can 

customize suitable UVLED curing machines according to the customer's process. Welcome to consult.
