What should you pay attention to after using flexible cutting plates?

1. What impact does the different blade angles of flexible blades have on cutting products?

 

    The blade angle design of the flexible knife blade is determined by the facial tissue, glue and base paper to be cut. The blades are available in 75°, 60°, 55°, 50°, etc. An experienced mold maker will determine the appropriate blade angle based on the cutting material details provided by the customer and combined with past experience.

    Choosing the wrong blade angle during design will affect the cutting effect and life of the mold. Generally speaking, the larger the blade angle, the longer the life of the mold; but if the blade angle is smaller, the cutting effect will be better, and the possibility of burrs around the label will be smaller. Generally, 75° is used for cutting coated paper, and for film products, the cutting edge angle should be below 60° to ensure that the surface material is cut rather than pressed.

 

2. Can the flexible blade be used to cut full cuts?

 

    Yes, the flexible knife blade can not only be used to make dotted lines for cutting and full penetration, but also cutting knives and in-mold labels for full penetration. Of course, waste disposal issues must be taken into consideration.

    The engraving circular knife can be made into an air-blasting or air-suction circular knife, but if the magnetic roller itself is a standard type without any air-blasting or air-suction device, the flexible knife blade will be used when cutting small holes or small grooves (anything smaller than 6mm in size). shape) there is a problem with waste disposal.

    Solutions that can reduce problems and increase the likelihood of success are: filling the blade with thin foam to discharge waste, or making the blade higher to make the contraction and expansion of the foam more effective.

 

3. What is the difference between the cutting material of the flexible knife blade and the engraving round knife?

 

    The flexible blade can be used to cut most self-adhesive surface materials, including paper films, and can also be used to cut thin cardboard.

    However, due to the problem that the blade can only be limited to (less than 2mm), there are limitations when cutting thick cardboard and foam materials. If used to cut hard aluminum or iron sheet materials, engraving round knives have inherent disadvantages in terms of life.

    However, because the flexible blade is made of CNC and does not require any manual molding, its cutting marks on the backing paper have an overwhelming advantage compared to the engraving knife with manual molding. The flexible blade is used in cutting self-adhesive materials. has its absolute advantages.

 

4. What information do I need to provide when ordering flexible knife blades?

 

     (1) The model of the rotary machine; (2) Information about the magnetic roller: tooth width, roller width, pillow shoulder diameter; (3) Cutting shape pattern, please note that the knife line diagram to be provided is after die cutting A shape drawing of the finished product, not a line drawing of the actual blade. If the circular die-cutting is used on the material, the line drawing on the actual blade is a mirror image of the shape drawing of the finished product after die-cutting; (4) The details of the material to be cut. There are several ways to tell the material details to the supplier: (a) the material supplier’s number and material schedule; (b) inform the type of top paper and bottom paper, and the thickness of the top paper and bottom paper; (c) send a Roll material to mold supplier.

 

5. What should you pay attention to when receiving the ordered flexible knife blade?

    To ensure that everything runs smoothly when put on the machine, after receiving the ordered flexible knife blade, you should first check whether the external packaging is intact. Then take out the knife skin and check whether the internal packaging is intact.

    Check the supplier's test results provided with the knife to see if the cutting shape, die-cut effect, and cut marks on the backing paper are ideal.

    It is best to open the package and carefully check that each blade is in the same condition as when it left the factory. After checking that everything is correct, repackage the inventory and prepare it for the machine.

 

6. Can the flexible blade be repaired after it wears out?

    In most cases, no. In addition to the above mentioned situations, add a layer of tissue paper, film or a layer of ink to the bottom of the knife plate for temporary adjustment.

    Although you can slightly repair the blade if you return it to the original factory, this is generally not recommended because the flatness of the blade cannot be guaranteed, and the marks on the backing paper after cutting cannot be guaranteed to be even.

 

7. How to maintain and prevent rust of flexible knife blade?

    The surface of the flexible knife blade should be cleaned of ink, glue and any other impurities after use. The surface of a good flexible knife blade has been specially treated to prevent rust and adhesive. These coatings can resist rust and adhesive in most cases.

    However, due to the wear and tear of the surface coating during die-cutting and possible back grinding, it is recommended to spray a little WD40 evenly after use and cleaning, and then seal and package it to achieve complete rust prevention.

 

8. How to package and place the flexible knife blade?

    Most flexible knife blades require edge bending, especially those suitable for small-sized magnetic rollers, which may require full bending.

 

    Therefore, flexible knife blades are mostly packaged in tubes. After use, the user sprays anti-rust agent on the flexible knife blades, seals them tightly in a plastic bag, and puts them back into the tube package in roll form. You can also use plastic bags to seal tightly and hang them upright.
