In the rapidly developing packaging industry, improving production efficiency and printing quality is an important challenge faced by every manufacturer. Pail bucket screen printing machine can meet the customized needs of different industries and different customers, and is gradually becoming an important tool for many companies to enhance their competitiveness.
Screen Printing Principle
The pail bucket screen printing machine uses a scraper to squeeze the ink so that the ink is transferred to the rotating barrel surface through the mesh of the graphic part under the state of close contact between the screen and the barrel surface, so as to realize pattern printing.
Screen Printing's Benefits
Strong Adaptability
Screen printing can be printed on surfaces of different shapes and materials, including flat, curved and round objects. Common substrates include cloth, plastic, glass, metal, etc.
High Precision
Screen printing can achieve high-precision pattern reproduction, especially suitable for large-area and small-batch pattern printing. Usually, the accuracy of screen printing can reach ±0.1 mm.
Bright Colors
The ink of screen printing is brightly colored, has strong coverage, and can ensure that the pattern is clearly visible on surfaces with different background colors.
Strong Durability
The printed pattern has strong wear resistance and UV resistance, suitable for long-term use, especially outdoors or in harsh environments.
Applications
When the pail bucket screen printing machine is used in the field of plastic products, it is mainly responsible for printing trademarks, patterns, text and other information on the surface of various plastic products such as plastic containers, plastic toys, and plastic signs. Plastic products are made of various materials and have large differences in surface polarity, which makes it difficult for ink to adhere evenly. In addition, static electricity may adsorb dust and affect the printing effect during the printing process. For plastic products of different materials, corona treatment, chemical primer and other pretreatments are performed before printing to increase the surface polarity to improve the adhesion of ink; you can install an electrostatic eliminator to remove static electricity on the surface of plastic products and avoid dust adsorption.
In the field of metal products, the pail bucket screen printing machine is mainly responsible for printing personalized patterns, corporate logos, scale logos and other tasks on the surfaces of metal plates, metal parts, metal crafts and other objects. The metal surface is smooth and dense, and the ink adhesion is poor. At the same time, the metal has strong thermal conductivity, which will affect the drying speed and curing effect of the ink. You can roughen the metal surface by sandblasting, grinding, etc. to increase the ink adhesion area; use infrared drying, hot air drying, etc. to adjust the drying temperature and time according to the thermal conductivity of the metal to ensure that the ink dries and solidifies quickly.
Pail bucket screen printing machine is used in the field of glass products. It is mainly responsible for printing exquisite patterns, decorative patterns, and text descriptions on various glass products such as glass cups, glass vases, and glass mirrors. However, the glass surface is smooth, the ink has high fluidity, and it is easy to produce flow marks; the thermal expansion coefficients of glass and ink are quite different, and the ink is easy to fall off when the temperature changes. You can perform a mild etching treatment on the glass surface with hydrofluoric acid to increase the surface roughness and improve the fluidity and adhesion of the ink. You can choose ink with a thermal expansion coefficient close to that of glass, and perform appropriate curing treatment after printing to make the ink and glass better combined, solving the problems of flow marks and ink falling off.
