Advantages of UVLED exposure machine compared with traditional exposure machine
1. Single band, high photoelectric conversion rate, uniform irradiation energy:
The traditional exposure machine (mercury lamp) is scattered light, which is composed of bulbs, electrodes and discharge gas. The wavelength of the emitted light source is between 350-450nm, the spectrum is long, the UV utilization rate is low, and the energy uniformity is only 70-80%; The UVLED exposure machine is a parallel light source, which emits 365nm/395nm single-band light source, has no clutter energy consumption, and the energy uniformity can reach 90%, which is suitable for the precision circuit industry.
2. High efficiency and energy saving:
The mercury lamp needs to be turned on in advance to preheat the device when it is in use, and it needs to be turned on all the time during work, which consumes a lot of power; UVLED uses UV diode chips to emit light, which can be instantly lit and the output energy can be set by itself, which is very energy-saving and easy to operate.
three. No harmful emissions, safe and environmentally friendly:
The traditional exposure machine (mercury lamp) emits a spectrum with a wavelength below 200nm, which will change oxygen O2 in the air to produce ozone O3 (the mercury lamp workshop will have a small smell), and the mercury lamp itself will also bring mercury pollution. There is no effective way to deal with mercury pollution; while the UVLED exposure machine is a light-emitting UV diode chip, which is the conversion of electrical energy into light energy. It is a clean and environmentally friendly curing method that produces pollution.
Four, long service life, no consumables:
The service life of the mercury lamp is 300-600h, and the mercury lamp bulb needs to be replaced regularly; the UVLED exposure lamp can be used for more than 20,000 hours, and the UVLED curing light source can be used for several years.
Screen printing exposure machine application:
The exposure unit is used in the filed of plate-making such as pad plate, screen plate, hot stamper plate, resin plate. when you put the film onto the plate into UV exposure machine, start it, the emulsion on the plate will appear a unseen imagine. this is important process on all plate-making technology
Screen printing exposure machine features:
1,adopting high quality lamps,which save electricity with long life.
2,timer with digtal readout.
3,set and operate very easily.
4,antomatic photographic shutter operation.
5,exposure time is accurate.
6,imported special blanket vacuum pump
7,the dimension could be done as the customer's requirements.

Performance characteristics
1. Adopting imported high-quality lamp (PHILIPS), long life, high light efficiency, accurate spectral output.
2. After power on, it can start-up instantly and also with automatic vacuum adsorption, exposing and other functions.
3. Highly vacuumed vacuum pump, high precision, stable performance, which ensures the close combination between the screen and the sample map, drying out of the screen pattern more clear and realistic.
4. Micro-motor controlled built-in exposure light shade; shading board out when exposing and shading board back when replacing screen, which can save time for replacing screen without switch exposure button.
Working principle
The use of vacuum pump pumping, pumping out of the air between glass table and the black rubber blanket to form a negative pressure, and rubber blankets are negative pressure will compress the screen, film, and then through the role of ultraviolet light can copy clear pictures.

UV-LED line light exposure machine advantages:
1, long life: life is more than 10 times that of traditional iodine gallium lamp funnel type exposure machine, about 25,000 to 30,000 hours.
2, cold light, no heat radiation, according to the film surface temperature is low, resolved exposure work long-standing problem of heat deformation affects line accuracy. Especially for high precision film exposure requirements applicable to small temperature rise of the occasion.
3, heat a small, solve the gallium lamp heat, staff in clean room unbearable problem.
4, instant light, no warm-up instantly reach 100% power UV output.
5, from the opening and closing times on long life.
6, high energy, light output stable, good illumination uniformity effect.
7, the effective radiation area size can be customized .
8, the maximum illumination intensity of up to 6000mw / cm2.
9, it does not produce ozone, it is to replace traditional light source technology a safer, more environmentally friendly choice.
10, low energy consumption, power consumption is only 10% of the traditional uv lamp type exposure machine can save 90% power.
11, small size, easy to carry, and only 1/8 the size of traditional funnel exposure machine.
12, the maintenance cost is almost zero, using Tamprinter UV-LED equipment annual savings of at least 1,000 $ / SET supplies costs
