Pad printing machines and screen printing machines are important equipment for graphic and text marking of products, and are an essential part of industrial production. However, it is necessary to consider widely how to choose a pad printing machine that meets the company's product printing requirements. Under normal circumstances, we must first understand the following conditions when choosing a pad printing machine:
1. The dimensions of the product to be printed and the printing position of the pattern
2. The size of the pad printing pattern
3. The number of colors of the pattern
4. Daily production
Next, we will examine the above problems to determine which pad printing machine is most suitable.
1. Product dimensions and pattern printing conditions
The shape of the product and the position of printing the pattern on the product directly affect the selection of front and back strokes of the pad printing machine.
The itinerary of the standard pad printing machine is divided into five types:
100MM stroke (eg: Z-P100D, Z-P100S2)
150MM stroke (such as: Z-P150D, Z-P150S2, Z-P150C2, Z-P150S4, Z-P150C4 ... etc.)
200MM stroke (such as: Z-P200D, Z-P200S2, Z-P200C2, Z-P200S4, F-P200C4, F-P200S6, C6, S8, C8 ... etc.)
250MM stroke (such as: Z-P250D, Z-P250S2, Z-P250S4, Z-P250C4 ... etc.)
300MM stroke (such as: Z-P300D, Z-P300S2, Z-P300S4, Z-PC300C4 ... etc.)
The longer the stroke, the more the rubber head protrudes from the steel plate after adhering ink to the face printing position, and the position of the pattern can print to tend to the middle position in the shape of the product. For example, we come to this situation: the printing pattern of some products is very small, but the external dimensions of its products are large, measured according to the printing area, but there is no front travel the stroke of the machine is 125mm. enough, no matter which way the products are placed on the workbench, there is no way for the print head to reach the position to print, so a model with a longer stroke is required longer to achieve.
2. The size of the printed pattern
The size of the printing pattern is directly related to the printing weight and the size of the steel plate For example: Normally, if the 100X100MM (standard) steel plate is placed on the oil pan machine, the maximum printing area: 75X75MM. By expanding the oil pan, the size of the steel plate can achieve a larger printing area, but the expansion of the oil pan to increase the printing area is only for single-color machines.
There are different names for the size of steel plates. In the market, everyone is used to using inches to describe them. For example, 100X100 steel plates are referred to as 4X4 steel plates, 100X150 steel plates defined as 4X6, and 100X200 steel plates defined as 4X8. The size of the steel plate and the printing area of each series of Zhengting models can refer to the specific performance parameters.
In addition, the size of the pattern that can be printed on each model is determined by the pressure generated by the cylinder bore of the print head. It does not mean that width can be to press the steel plate as much as possible. the longer the length, the narrower the width, because the print head cylinder can only take so much pressure to print.
3. The number of colors of the pattern
The number of colors of the pattern is easy to understand. In general, there are several colors on the product. Usually, it is necessary to consider using a multi-color pad printing machine. Zhengting pad printing machine can provide 2-8 color printing requirements You can choose the pad printing machine with rotary table type and shuttle type, which can register accurately and delicate pattern and text printing.
4. Daily production
It can also be said that the number of products produced is the most important reason for choosing pad printing. At present, there are usually two types of pad printing machines in the form of a rotary table or a shuttle type. The speed of the turntable is the fastest, whether it is two-color, four-color, six-color, or eight-color, the speed of the turntable is the same, because the This model prints all colors in one production. circle However, there are advantages and disadvantages to the
