The machine HY-175N in the video is upgraded from standard serie HY-175, it’s customized for printing and discharging metal tubes like eyebrow pencils, UV curing system isn’t needed because UV ink doesn’t apply on metal tubes, but servo module discharging system is necessary to automatically unloading the printed tubes on the nail plates, then the worker takes the plates to wind box for drying it.
It is driven by a 12 stations vertically mounted rotary indexing table that is equipped with a high-end European SITI brand (Italian) main drive motor.
Screen printing has the advantages of large batches, low prices, bright colors, long shelf life, and fast delivery. It is recognized by more and more industries and is widely used.
Screen printing consists of five elements:
Screen printing plate, squeegee, ink, printing table and printing object;
Different screens are suitable for different products, nylon screen has good abrasion resistance, suitable for plastic printing.
Ink:
Screen printing inks are generally divided into UV inks and PU inks. PU inks are not wear-resistant, so they can only be printed on the primer, and then sprayed with a top coat for protection;
UV ink has excellent adhesion and abrasion resistance, and can be silk-printed on the top coat to greatly improve production efficiency. It is currently widely used in production.
The advantages of silk screen printing:
1. Not limited by the size and shape of the object.
Generally, printing can only be performed on a flat surface, but screen printing can not only print on a flat surface, but also print on a molded object with a special shape, such as a spherical curved surface. Anything with a shape can be performed by screen printing.
2. The layout is soft and the printing pressure is small.
The screen is soft and flexible.
3. Strong ink coverage.
It can be used for pure white printing on all black products with strong three-dimensional effect.
4. Applicable to various types of inks.
5. Strong light resistance.
The gloss of the printed matter can be kept unchanged. (The temperature and sunlight have no effect). This eliminates the need for additional laminating and other processes when printing some stickers.
6. Flexible printing methods.
7. Convenient plate making, low price, and easy-to-master technology.
8. Strong adhesion.
9. It can be silk-screened by hand or machine-printed.
10. Suitable for long-term display, and expressive outdoor advertising.
