We all know that the existing UV photosensitive materials on the market can basically be cured by UV curing lamps, including photosensitive resins in 3D printing. Photosensitive resin prints are very thin and soft after a period of time. At this time, it is necessary to use a UVLED curing oven for secondary curing. In general, the higher the light power, the better the curing effect.
However, in practical applications, the higher the power of the UVLED curing oven, the better the curing effect and the faster the curing speed. Is this true? In fact, this also requires the selection of UVLED curing ovens with appropriate wavelength and power according to the characteristics of different photosensitive materials. how to choose? We should consult the photosensitive grease manufacturer and the UVLED curing oven manufacturer, and determine the purchase after comprehensive consideration of the test.
The power of the UVLED curing oven is the UVLED radiant energy, also known as the penetrating power. First, it needs to meet the spectral wavelength and power density requirements of UV ink (varnish) absorption. If the power of the UVLED curing oven is not enough, even if the light duration is long and the number of UV curing devices is large, the product will not be fully cured. Conversely, it also ages, seals and embrittles the surface layer of UV inks (varnishes). At the same time, the adhesion of the ink (varnish) is also not good, which will make the overprinted interlayer bonding force worse. Since the low power UV curing light cannot penetrate the bottom of the ink layer, the bottom is not cured or insufficiently cured.
In this case, UVLED curing oven has obvious advantages over UV mercury lamp. The higher the power of the UV mercury lamp, the greater the heat, and the mercury lamp tube generally needs to be replaced every 800-1000 hours, which is not friendly to heat-sensitive materials and delays production efficiency. As a cold light source curing machine, Height-LED UVLED curing oven has a good heat dissipation design. Even if it runs with high power for a long time, the temperature of the device will not rise very high, and there is no need to replace the lamp beads. Therefore, as long as we communicate with the photosensitive material manufacturer about the wavelength required for curing, the UVLED curing oven can complete the curing well. Of course, the higher the power of the UVLED curing oven, the better the effect. Good curing requires the combined action of power, wavelength, irradiation distance, irradiation time and other factors to achieve better curing effect.
