There are some differences in the operation process between machine-printed silk-screen silicone and manual silk-screen silicone. The following are the specific operation steps of the two:
Machine-printed silk-screen silicone operation
Silicone preparation: Mix the silicone and curing agent in a certain proportion. The selection of silicone is very important. The appropriate type and hardness of silicone should be selected according to the specific printing needs. The amount of curing agent added also needs to be controlled. Too much will cause the silicone to cure too quickly, affecting the printing effect.
Screen production: According to the pattern design to be printed, make the corresponding screen. The selection of the screen should be determined according to the size and fineness of the printed pattern. Generally, screens of different meshes are used to achieve different effects.
Printing preparation: Pour the prepared silicone into the silicone tank of the printer, adjust the pressure and speed of the printer, install the screen and adjust it. At the same time, prepare the substrate to be printed, clean the surface to ensure dust and oil free.
Start printing: Start the printer, apply the silicone evenly on the screen, and then print the silicone onto the surface of the substrate by pressure. During the printing process, it is necessary to pay attention to controlling the speed and pressure of the printer to ensure uniform and consistent printing effects.
Curing: After printing, the silicone needs to be cured. Generally, drying or UV curing is used to ensure that the silicone is completely dry and cured. The curing time and temperature need to be determined according to the type and thickness of the silicone. Too short will cause the silicone to not be completely cured, and too long will affect production efficiency.
Inspection and packaging: After curing, the printing effect is inspected. Check the clarity, color saturation and other indicators of the printed pattern to ensure that they meet the requirements. Finally, the printed products are packaged to prevent surface damage.
Manual silk-screen silicone operation
The operation process of manual silk-screen silicone is similar to that of machine-printed silk-screen silicone, but it focuses more on manual operation. The following are some key steps:
Glue dilution: Mix the silicone and diluent evenly until it becomes a liquid gel. The amount of diluent added can be adjusted according to actual needs to obtain a viscosity suitable for printing.
Color glue: Add an appropriate amount of color paste or pigment to the diluted silicone and stir it thoroughly to obtain the silicone of the desired color.
Prepare the screen and substrate: Select a screen suitable for the pattern and prepare the substrate to be printed. Make sure the screen is clean and unblocked, and the surface of the substrate is clean and dust-free.
Manual printing: Pour the adjusted silicone on the screen, and use a scraper or scraper to gently spread the silicone so that it is evenly coated on the screen. Then press the screen on the substrate with your hands or tools, and print the silicone onto the surface of the substrate by pressure.
Curing treatment: After printing, curing treatment is also required. Choose the appropriate curing method and time according to the type and thickness of the silicone.
Subsequent treatment: After curing, check the printing effect to ensure that it meets the requirements. Then carry out necessary cleaning and packaging.
Differences
Efficiency and precision: Machine-printed silk-screen silicone usually has higher production efficiency and printing accuracy, which is suitable for large-scale production. Manual silk-screen silicone is more flexible and suitable for small batch or personalized production needs.
Operation difficulty: Machine-printed silk-screen silicone requires professional printing equipment and operating skills, and has high skill requirements for operators. Manual silk-screen silicone is relatively simple and easy to learn and master.
Cost: The equipment and material costs of machine-printed silk-screen silicone are usually high, but the production efficiency is high, which is suitable for large-scale production to reduce unit costs. Manual silk-screen silicone has a lower cost, but the production efficiency is relatively low.
In summary, there are differences in the operation process between machine-printed silk-screen silicone and manual silk-screen silicone, and each has different characteristics and applicable scenarios. In actual applications, the appropriate printing method can be selected based on production requirements, cost budget, and operating skills
