Can a flexible blade be made into a double or multi-layer type?
can. For example, the label is cut in half and the dashed lines between the labels are cut. Or some blades on the multi-layered label paper cut the first layer, and some blades cut the first and second layers of material. In order to avoid the problem of runout of the die during high-speed operation, the distance between the fully-cut cutter wire and the cutter wire should preferably be 3 mm.
What is the effect of the different blade angles of flexible blades on the cutting product?
The blade angle design of the flexible blade is determined by the combination of face paper, glue and backing paper to be cut. The blade has 90°, 80°, 70°, 60° and so on. Experienced toolmakers will use the cutting material details provided by the customer, combined with past experience to determine the appropriate cutting edge angle. Selecting the wrong blade angle at design time will have an effect on the cutting effect and life of the die. In general, the blade angle is larger and the life of the mold is longer. However, if the angle of the blade is small, the cutting effect will be better, and the possibility of flashing around the label is less likely.
Can a flexible blade be used to cut all wear?
Although not ideal, many customers choose flexible blades for cost savings or fast delivery times. The flexible blade can not only be made into a full-cut, dashed line, cutting blade, but also used to process the fully-cut in-mold label. Of course, in addition to life, we must also consider the issue of waste. Engraving round knife can be made into air or air suction round knife, but if the magnetic drum itself is a standard type without any air or air suction device, flexible blade when cutting small holes or small slots (any smaller than 6mm size There is a problem with waste. Programs that can reduce the likelihood of problems and increase success are: using thin foam to fill the blade edge, or raising the blade edge to make the foam shrink and expand more effectively.
What is the difference between the cutting material of a flexible blade and a round knife?
Flexible blades can be used to cut most of the adhesive surface materials, including paper film, can also be used to cut thin cardboard. However, due to the problem of shorter blades, there is a limit to cutting thick cardboard and foam materials. If it is used to cut hard aluminum or iron sheet materials, the life cycle of engraving round knife has its inherent weakness. However, due to the fact that the flexible blade is completed by the CNC without any manual trimming, the traces cut on the bottom paper are overwhelmingly superior to those of the manual trimming sculpting tool. The flexible blade has an advantage in cutting the adhesive material. Its absolute advantage.
Order flexible blade need to provide that information?
(1) The model of the rotary machine;
(2) The data of the magnetic roller, including the number of gear teeth, the diameter of the pillow shoulder and the roller body;
(3) Cut the pattern of the shape. Note that the cut line pattern to be provided is the shape of the finished product after die cutting, not the line pattern on the actual die plate. If the circular die cutting is used on the material, the actual pattern on the tool plate is the mirror image of the shape after the die cutting;
(4) To cut the details of the material. There are several ways to tell the supplier about the details of the material: a) the material supplier's number and bill of materials; b) telling the type of top and bottom paper, the thickness of the top and bottom paper; c) sending a roll of material to Mold supplier.
What should I check after receiving the ordered flexible blade?
In order to ensure that everything runs smoothly on the machine, after receiving the ordered flexible blade, it should first check whether the external package is intact. Then remove the blade and check if the inner package is intact. Inspect the supplier's test results provided with the knife to see if the cutting shape, die-cutting effect, and cutting marks on the base paper are satisfactory. It is best to open the package and carefully check that each blade is as good as the factory. After checking everything, the inventory is repacked and ready for use.
Can the flexible blade be repaired after it has worn out?
In most cases, it cannot. In addition to the above-mentioned situation, a thin layer of thin paper is applied to the bottom of the plate, and the film or the layer of ink is applied for temporary adjustment. If you return to the original factory, you can also do a slight repair of the blade, but in general it is not recommended to do so, because the flatness of the blade can not be guaranteed, the trace on the bottom paper after cutting is difficult to ensure uniform.
How to maintain and rust-proof flexible blades?
After the flexible blade is used up, its surface should be cleaned of ink, glue and any other impurities. Rothley flexible blades are resistant to rust in most situations with the introduction of the popular European surface treatment method, together with chemical components that are particularly resistant to rust. However, due to the abrasion of the surface coating treatment during die-cutting and the possible back-grinding, it is recommended to apply a small amount of WD40 evenly after use and cleaning, and then seal the package to achieve a complete rust-proof purpose.
How to pack and place flexible blades?
Most flexible blades require edge bending, especially for small size magnetic rollers, which may require full bending. Therefore, the packaging of the flexible blades is mostly packaged in tubes. After the user uses them, the rust inhibitor is sprayed on the flexible blades, sealed tightly with a plastic bag, and packaged in a roll-like manner. It can also be placed in a plastic bag and placed straight after being sealed.
The above questions and answers are frequently encountered and raised by Mr. Bill Shen, who has summarized the use of magnetic rollers and flexible blades for many years in many trademark manufacturers in the Asia Pacific region. Having lived in Australia for 17 years and promoted in the rotary die industry for nearly 12 years, Mr. Shen returned to China in early 2007 and founded Rotheley (Guangzhou) Technology Co., Ltd. The introduction of the top European production equipment, processes and raw materials, the wholly foreign-owned enterprise Rotheley (Guangzhou) Technology was put into operation in Huadu, Guangzhou in early 2007 and began to supply the flexible blades and magnetic drums needed to serve China and the Asia-Pacific market.
