Basic operation method of fuel injection processing
With the rapid development of plastic industry and the continuous improvement of plastic functions, plastic parts have been more widely used. Plastic parts are replacing traditional metal parts in different fields. A well-planned plastic part can often replace many traditional metal parts, and then simplify the product structure and save manufacturing costs. Intention. About the oil-jet processing is generally engaged in plastic spray, screen printing, transfer printing processing; EVA, rubber and other shoes color, screen printing. Plastic fuel injection has spraying line, screen printing line, pad printing machine and other equipment.
Oil-jet transfer printing is a kind of surface treatment technology, and surface treatment is a general term for all kinds of surface processing technology, is an old and extensive process. From top to bottom; horizontal appearance should be done in the direction of light. Brush: paint is painted on the surface of the object by artificial brush. Oil-spraying-coating refers to the process of forming a coating on the surface of a certain substrate, which has excellent adhesion, wear resistance, chemical resistance and other special functions, such as conductivity. For products, it is a good way to beautify and increase the value.
Plastic products can be painted, painted or painted. Because the workpiece is too large, baking is not convenient and suitable for the protection of the device, so painting and spraying paint is a common basic method in paint construction. Its characteristics are: saving paint, simple things, convenient use, easy to grasp, and strong sensitivity. The defect is: labor intensity is big, productivity is low. The applicability of fast-drying paint is poor, if the operation is not skilled, the film is prone to cracks, hanging and uneven defects.
Before painting, the paint must be mixed evenly (to prevent the deposit of pigment in the deposit period), and adjust to the appropriate viscosity, generally to judge by experience: that is, after brushing the paint lifted, 30-50 drops per minute needle of natural flow / is appropriate. Less staining and more brushing, from top to bottom, from left to right, first inside and then outside, first inclined straight, first difficult then easy, vertical and horizontal brushing. Finally, I should pay attention to it once again.
The function of screen printing is almost the same. Screen printing is to use a transfer machine. The words of screen printing are relatively simple. Hand printing can also be done. However, the screen printing is relatively stable, but not sensitive. Some products can only do screen printing, and some can only use screen printing, each has its own advantages. Transfer printing is the use of imaging principle, the original plan to print the picture into a film, and then the picture will be etched on the steel plate. This is a delicate process, once the film, is fundamentally decided, if the printing effect is not satisfied with the film with the change. After drying the steel plate, install it on the oil plate of the printer, transfer the picture to be printed on the plate to the product to be printed with the silicone head of the printer. The efficiency of pad printing is high, and the effect of manufacturing is more delicate and beautiful.
In the meantime, the most extensive use of oil-jet transfer printing, its application and development in modern times can be said to be a thousand miles, a variety of paints and sensitive transfer printing method is eye-catching, in the appearance of the product its role and value is vividly displayed.
