Surface Treatment Process

9. Carving.

Carve, also known as laser engraving or laser marking, is a process of surface treatment using optical principles. A laser beam is used to carve permanent imprints on the surface of a substance or inside a transparent substance.

10. Electric spark processing.

Electric spark processing (EDM) is a special processing method for the erosion of conductive materials by using the electrocution effect generated by pulse discharge between the poles immersed in the working fluid, also known as discharge processing or electroresist processing, or EDM for short. Tool electrodes are commonly used in corrosion-resistant materials with good conductivity, high melting point and easy processing, such as copper, graphite, copper tungsten alloy and tantalum. During processing, tool electrodes are also lost, but less than the amount of wear and tear of the metal of the work piece, or even close to no loss.

11. Laser bite flowers.

Laser bites are treated with high energy density laser reactions with steel surfaces, forming snake skin/corrosion/pear or other forms of texture.

12. Transfer printing.

Shift printing is one of the special printing methods, that is, the use of steel (or copper, thermoplastic plastic) gravate plate, the use of silicone rubber material made of surface transfer head, the gravvate ink to the surface of the transfer head, and then to the required object surface press can print text, patterns and so on.

13. Screen printing.

Screen printing is the silk fabric, synthetic fiber fabric or wire mesh on the mesh frame, using hand-carved film or photochemical plate making silk screen plate. Modern screen printing technology, is the use of photosensic materials through photographic plate making methods to make screen plates (so that the screen plate on the part of the screen is a through hole, rather than the screen hole of the text section is blocked). When printing through the scraper squeeze, so that the ink through the image part of the mesh hole transferred to the print, forming the same as the original text.

14. Direct thermal printing.

Direct thermal printing refers to a method of applying thermal agent to paper, making it a thermal recording paper, thermal recording paper under the effect of heat, so that the material (color agent) changes in physical or chemical properties and obtain an image.

15. Heat transfer.

The principle of thermal transfer is to transfer the data pattern through the printing machine to special transfer ink printing on the transfer of special paper, and then to a special transfer machine, high temperature and high pressure will be accurate transfer of the pattern to the surface of the commodity, to complete the product printing.

16. Plate printing.

Printed because the printed part of the text and non-graphic parts on the same plane, in printing, in order to enable ink to distinguish the pattern part of the plate or non-pattern part, the principle of oil and water separation, first of all by the water supply device of the plate parts to the plate of the non-graphic part of the water supply, thereby protecting the non-graphic part of the plate from ink immersion. The ink is then supplied to the plate by the ink supply device of the printed part, and since the non-text part of the plate is protected by water, the ink can only be supplied to the printed part of the text. Finally, the ink on the plate is transferred to the milk skin, and then use the pressure between the rubber roller and the imprint roller, the ink on the nipple is transferred to the substation, complete a printing, so that the printing is an indirect printing method.
