- Precise 20" x 24" Vacuum UV Exposure Unit 50cm x 60cm Screen Printing Machine
Our Precise Vacuum UV Exposure Unit is equipped with special UV lamps and auxiliary vacuum suction device. After putting the screens and well printed transparency film on the glass, close its cover and let it work after set the needed vacuum and exposure time, then it will make the screens and transparency film close on the glass tightly by evacuating the air of the vacuum chamber emerging from the rubber blanket. When the set time is up, it will deflate automatically, then the exposure is finished. Please cut off the power supply.
It has the same exposure effect with the exposure unit exposed of iodine gallium light. Even if its exposing time is a little longer, but because of its small volume, light weight, low cost and easy transporation, which is much fit for small business and family workshop for making screens with high precision.
Screen printing screens are coated with a light sensitive emulsion using a scoop coater. When the emulsion is dry, place a positive print of your image on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate.
1.Rational design & easy operation: based on humanity and practicality principles, with the elaborate designed table type structure, it’s much easier for screen exposure with high precision.
2.Independement settings of vacuum and exposure time with automatic memory function: The vacuum time and exposure time can be set up separately just according to actual requirements (setting ranges: 0-999 seconds); When exposure is finished, the power supply of the lamp will be automatically cut off, it will deflate and beep by itself, then please turn it off. When you need exposure again, just connect the power supply, then it will work automatically according to your former settings because of its automatic memory function.
3.Oilless vacuum pump with high quality is durable with no need for oil injection.
4.8 pieces of special UV exposure lamps will guarantee a precise and even exposure effect.
5.The high strength toughened glass (thickness: 0.24”/6mm) is with high press resistance and not easily scratched. Besides, once broken, it will turn into pieces without sharp edges to avoid user’s injury.
6.All-metal construction & elegant appearance with advanced electrostatic paintings, easy to clean and no rust.
