UV exposure machine for screen plate

1. Ease of operation

• Simple interface: This type of vacuum screen printing machine usually has a simple and clear operation interface. It may have only a few basic buttons to control the main process of printing, such as exposure time setting, vacuum adsorption start and stop, etc. For example, the operator can set the exposure time through simple digital keys, and the time range can range from a few seconds to a few minutes, which can be flexibly adjusted according to the type of screen and the characteristics of the photosensitive material.

• Automated function assistance: Some advanced models have automated functions that can automatically detect whether the vacuum degree meets the requirements, and the exposure process will not start until the vacuum degree reaches the set standard. Moreover, after the exposure is completed, the vacuum state will be automatically released, making it convenient for the operator to remove the screen. Such an automated process design greatly reduces the complexity of manual operation and reduces the requirements for the professional skills of the operator.

• Simplified operation steps: The entire printing process steps are clear and concise. The operator first places the prepared photosensitive screen on the workbench of the printing machine, then puts the film, closes the cover of the printing machine, starts the vacuum adsorption, and presses the exposure button after the vacuum adsorption is stable. The whole process does not require complicated operating skills, and novices can master it after simple training.

2. Low cost

• Equipment price advantage: Compared with large and high-end exposure equipment, this easy-to-operate vacuum screen exposure machine is relatively cheap. It is designed mainly for small printing workshops, advertising production stores and other user groups that are more sensitive to cost. The price of the equipment may be only a fraction of the same type of advanced exposure machine, allowing small businesses and entrepreneurs to enter the screen printing field at a lower cost.

• Strong versatility of consumables: In terms of consumables, it can use more common photosensitive materials and screens. These consumables are easy to obtain in the market and the price is relatively stable. For example, the commonly used polyester screen and diazo photosensitive glue are relatively low in cost and can meet most of the needs of screen printing, such as making simple T-shirt printing screens, advertising banner screens, etc.

• Low maintenance cost: The structure of the equipment is relatively simple, without complex mechanical and electronic components. This makes its maintenance cost low, and generally only simple maintenance work such as regular replacement of vacuum pump oil, cleaning of vacuum pipes and inspection of light sources is required. These maintenance tasks do not require professional technicians and expensive repair tools, reducing the long-term use cost of the equipment.

3. Power-saving performance

• Energy-saving light source design: This type of plate exposure machine usually uses energy-saving ultraviolet light sources, such as metal halide lamps or LED ultraviolet lamps. These light sources have high energy conversion efficiency while ensuring sufficient exposure intensity, which can effectively reduce the consumption of electricity. For example, the energy consumption of LED ultraviolet lamps is only about half of that of traditional mercury lamps, and their service life is longer, reducing the frequency and cost of replacing light sources.

• Intelligent power management: Some plate exposure machines are equipped with intelligent power management systems that can automatically adjust the power of the light source according to the exposure time. At the beginning of exposure, the photosensitive material is quickly brought to the exposure threshold at a higher power, and then the power is automatically reduced to maintain the exposure state. This intelligent adjustment method saves electricity to the greatest extent while ensuring the quality of the plate exposure.

4. High-precision characteristics

• Vacuum adsorption system ensures accuracy: High-precision vacuum screen plate exposure machines have an efficient vacuum adsorption system. During the plate exposure process, the strong vacuum adsorption force can tightly fit the screen and the film to ensure that there is no gap between the two. This can effectively prevent light scattering, make the exposure more uniform and accurate, and thus improve the platemaking accuracy of the screen. For example, the vacuum degree can reach above -90kPa, which can make the screen and the film fit at a very high level.

• High-precision exposure control: In the exposure process, the platemaking machine uses a high-precision timer and light intensity control system. The timer can accurately control the exposure time, and the error can be controlled within ±1 second. The light intensity control system can accurately adjust the intensity of the ultraviolet light source according to different photosensitive materials and platemaking requirements to ensure the accuracy of the exposure dose. Through these high-precision control measures, high-precision and clear-patterned screens can be produced to meet the needs of high-precision screen printing, such as electronic component printing, high-precision label printing, etc.
