Equipment Debugging
Select High-precision Equipment: Give priority to selecting equipment with advanced intelligent control technology, such as CNC cutting machines. Such equipment can make the cutting process accurate to the micron level, and can accurately cut straight lines, curves, and complex shapes. At the same time, select suitable cutting tools according to the characteristics of the sticker material. For example, a drag knife is more suitable for cutting various paper stickers, which can achieve clean and highly precise cutting. When choosing high-precision equipment, the cutting should be accurate and meticulous.
Adjust Cutting Parameters: Accurately adjust parameters such as the speed, angle, feed rate, and retract rate of the cutting knife according to the size, shape, and material thickness of the sticker. For example, for thicker sticker materials, it may be necessary to reduce the cutting speed and increase the feed depth to ensure that the sticker is completely cut through without damaging the backing layer. For thinner stickers, the cutting speed should be appropriately increased to reduce the contact time between the blade and the material and avoid excessive cutting. Adjusting the cutting parameters is a method of fine cutting, which can better ensure the precision of kiss-cut labels.
Mold Making
Precisely Design the Mold: Use professional computer-aided design software to accurately draw according to the design size and shape of the sticker. When designing, consider the pattern details, edge contour of the sticker, and the separation requirements from the backing layer, etc., to ensure that the mold can accurately cut out the required sticker shape and that the cut sticker can be easily peeled off from the backing layer.
Ensure the Quality of the Mold: Select high-quality mold materials, such as steel or hard alloy, etc., to ensure that the mold has sufficient rigidity and wear resistance, can withstand the pressure and friction during the cutting process, and is not easy to deform or wear. During the mold making process, strictly control the machining accuracy. Through precision machining equipment and processes, ensure the dimensional accuracy and surface quality of the mold, so that the cutting edge of the mold is sharp and uniform to achieve precise cutting.
Material Preparation
Material Flatness: Before cutting, ensure that the sticker material to be cut is completely flat, without wrinkles, bends, or warping. Uneven materials will lead to uneven contact between the blade and the material during the cutting process, affecting the cutting precision and may even cause cutting deviation or blade damage. For materials of slightly lower quality, they should be picked out first, and in subsequent processing, try to produce products from these materials as much as possible to avoid waste.
Material Consistency: Ensure that the thickness, hardness, and other characteristics of the sticker material are consistent throughout the entire roll or sheet of material. If there are situations of uneven thickness or large differences in hardness in the material, the resistance received by the blade during cutting will be different, resulting in inconsistent cutting depths and affecting the effect and precision of kiss cutting. In terms of the rotation of the material, it should also be consistent. Otherwise, during production, it is very likely to get stuck or have inconsistent quality, which will make the ordering customers dissatisfied with this batch of products, and it will be difficult to have the possibility of a second cooperation.
Operation Process
Properly Place the Material: Place the sticker material accurately on the workbench of the cutting machine and use a positioning device or fixture to fix it firmly to prevent the material from moving or shaking during the cutting process. At the same time, ensure that the edge of the material is parallel to the coordinate axis or reference line of the cutting machine to facilitate the precise control of the cutting path. Only by properly placing the material can the machine be installed for production to avoid deviations in the material during the production process and the production of products of poor quality.
Operator Skills: Operators need to receive professional training, be familiar with the operation method and performance of the cutting machine, and be able to skillfully set parameters, adjust tools, and perform cutting operations. During the operation process, strictly follow the operation procedures, stay focused, and deal with problems that occur during the cutting process, such as tool clogging and material deviation, in a timely manner. Provide skill training for the company’s employees to improve their skills and make production more efficient.
Quality Inspection
First-piece Inspection: Before formal mass cutting, perform the first-piece cutting first and conduct a comprehensive inspection of the first-piece product, including the shape, size of the sticker, the quality of the cutting edge, and whether there are situations such as missed cutting or excessive cutting. If problems are found, adjust the equipment parameters or the mold in a timely manner until the first-piece product meets the quality requirements. For the products produced, they should be carefully inspected to ensure, as much as possible, that the product quality is excellent and provide customers with satisfactory label products. If you want all products to meet the standards, then all products should be checked and inspected.
Process Sampling Inspection: During the mass cutting process, conduct sampling inspections regularly to ensure the stability of the cutting quality. The frequency of sampling inspections can be determined according to the production quantity and product requirements. Generally speaking, when the production quantity is large, the sampling inspection frequency should be appropriately increased. For individual unqualified products found, analyze the reasons in a timely manner and take corresponding corrective measures, such as adjusting the tool, cleaning the equipment, etc. During the process, regularly check the production equipment to avoid problems during the production process that affect the production progress.
Equipment Maintenance: Regularly maintain and service the cutting machine and the mold, check whether the mechanical components, transmission system, tools, etc. of the equipment are working normally. If there is wear or damage, replace or repair them in a timely manner. At the same time, clean the dust, debris, and other impurities on the surface of the equipment and the mold, and keep the cutting work area clean to ensure the precision and stability of cutting. Maintain the production equipment and check the equipment to ensure production efficiency.
