The aspects that should be paid attention to when choosing a labeling machine

In-mold labeling machine is a kind of mechanical and electronic equipment that combines mechanical, electrical, pneumatic, optical, and magnetic. In the packaging process of the product, labeling is the top priority of the subsequent packaging process. With the advancement of economic globalization and China's successful entry into the WTO, in-mold labeling machines are playing an increasingly important role in the product packaging process. So what machine is the best in-mold labeling machine? How does the manufacturer choose a good labeling machine? Based on my many years of production experience, I have summarized the opinions of thousands of on-site engineers from plastic manufacturers and provided some suggestions for your reference only. The selection of the in-mold labeling machine should pay attention to the following aspects: 1. First is the choice of the standard library: The standard library is related to the yield problem, the material of the standard library must be made of steel to ensure long-term repeated use; the standard library must be up and down , Left and right, rotating, front and rear can be easily and reliably adjusted; the stop rod of the standard library must have a strict and firm verticality to ensure the free sliding of the label; the current popular method of the stop rod and the frame of the standard library is to use wire cutting Square holes and square rods to ensure the stability of the fixation; the stop of the benchmark rod is a very important and easily overlooked link, which must be processed by CNC lathe. 2. Then there is the choice of arm and suction cup: The arm must be flexible, its length must be easy to adjust, and the arm must not touch the mold, so the material of the arm is preferably aluminum alloy; the suction cup is very important, the suction cup should be transparent and high Flexibility, the skirt of the suction cup must be thin and soft, which is easy to overlook by many manufacturers. 3. After that, it is the weight and center of the equipment: The inner labeling machine equipment must have a certain weight. Now many manufacturers reduce the weight of the machine in order to reduce costs, which brings a lot of noise and tremor; the center of gravity of the equipment must be at the machine's In the center, the best detection method is to run the equipment to the forefront, and use the pressing method to perform preliminary detection. When the center of gravity of the equipment is wrong, the vibration caused by the repeated movement of the equipment is extremely unfavorable to the equipment. 4. Finally, the configuration and price of the equipment: Pay attention to the overall structure of the equipment, to achieve the same function, the less structure, the better. Regarding equipment configuration, general customers pay more attention to the main controller, lead screw, and motor. They don’t pay enough attention to the basic electrical components that are frequently used and have a high damage rate. This is a misunderstanding when selecting equipment. Pay attention to the basic electrical configuration and set the layout and wiring specifications; the price depends on the benevolent, the wise see the wisdom, it is recommended to look at the price-performance ratio. Regardless of the standard library, arms, suction cups, weight, or electrical parts configuration, think about what customers think, use them for customers, strive for perfection in product quality, and continue to improve the in-mold goal toward accuracy, efficiency, zero-waste standard, durable, and cost-effective. The quality of the labeling machine.
