More and more enterprises in the purchase of in-mold labeling machine, then when the purchase should pay attention to those problems? In-mold labeling machine is a kind of mechanical and electronic equipment, which combines machine, electricity, gas, light and magnetic as a whole. In the packaging process of products, labeling is the most important part of the packaging process. With the advancement of economic globalization and China's successful entry into WTO, in-mold labeling machine is playing an increasingly important role in the process of product packaging, so what is the best in-mold labeling machine? How do manufacturers choose a good labeling machine? The first is the selection of the standard library: the standard library is related to the rate of finished products, the material of the standard library must be made of steel, to ensure long-term repeated use; The library must be up and down, left and right, rotation, front and back can be convenient and reliable adjustment; The bar of the library should have strict and firm perpendicularity to ensure the free sliding of the label before and after; The standard library bar and the standard frame is now popular practice is to use the square hole and square rod of wire cutting, in order to ensure fixed stability; Benchmarking head is a very important link easy to ignore, must use CNC lathe processing. Then the choice of the arm and the sucker: the arm must be flexible, easy to adjust the length, and the arm must not hurt the mold, so the material of the arm is best alloy aluminum; The suction cup is very important. The suction cup should be transparent and have high flexibility. The skirt edge of the suction cup must be thin and soft, which is easy to be neglected by many manufacturers. Then, it is the weight and center of equipment: equipment should have a certain weight, now many manufacturers in order to reduce the cost of reducing the weight of the machine, so bring a lot of noise and tremor; The center of gravity of the equipment must be in the center of the machine. The best detection method is that the equipment runs to the front end and is initially detected by pressing. When the center of gravity of the equipment is wrong, the vibration caused by repeated movement of the equipment is extremely adverse to the equipment. Finally, the configuration and price of the equipment: the overall structure of the equipment should be paid attention to, to achieve the same function, the less structure the better. About equipment configuration, general customers focus on the main controller, lead screw, motor, for frequent use of high, high damage rate of basic electrical components attention is not enough, this is a mistake when choosing equipment, that is, we must look comprehensively, especially to pay attention to the basic electrical configuration, set layout and wiring specifications.
