Die Cutting Machine Frequently Asked Questions

1.Uneven die-cut marks and insufficient depth When round-pressing circular die-cutting of self-adhesive materials, sometimes uneven die-cutting marks and insufficient die-cutting depth occur because the die-cutting knife does not completely cut the surface material. Cut off, causing the waste edge to take away the label surface material during the pulling process. When encountering this situation, you can try the following solutions: First, check whether the pressure of the die-cutting knife is uniform, and adjust the die-cutting seat to apply it on the die-cutting surface. the pressure on the knife; the second is to ensure that the die-cutting knife cuts through the label surface material. For a new die-cutting knife, if it is initially used, it will require greater pressure. If the material can be cut, it means that the height of the die-cutting knife does not match the material parameters or the height of the die-cutting knife has a large tolerance to the target height during production.                                                                                                                                                                                                                                          

2.The width of the waste edge in the paper feeding direction is smaller than that in the axial direction.The waste discharge edge in the paper feeding direction serves as the main force for waste discharge. If its width is smaller than the axial waste discharge edge width, it will be easy toCause the waste discharge edge to break.It is recommended that before production, first ensure that the width of the waste discharge edge in the paper feeding direction is greater than or equal to the width of the axial waste discharge edge. Secondly, in the early label settingWhen timing, also consider the stress in the paper feeding direction, and appropriately widen the width of the waste discharge edge in the paper feeding direction, which can effectively avoid the breakage of the waste discharge edge.Case.                                                  

3.Material peeling force is too large Excessive peeling force applied to the self-adhesive material will make it difficult to separate the surface material and the backing paper, causing the waste discharge edge to be easily broken. When die cutting, you should Choose the appropriate adhesive and control its peeling force within the appropriate range. In addition, you should also ensure that the silicone oil is evenly coated on the edge of the label. Materials with special requirements need to be replenished with silicone oil on the edges to ensure that the material peeling force is applied evenly. The end surface of the self-adhesive slitting roll is defective If there are defects on the end surface of the self-adhesive slitting roll such as burrs, glue overflow, and damage, the waste edge will easily break during die cutting. This requires fucking When cutting self-adhesive materials, operators pay special attention to controlling the cutting quality to avoid burrs and stained gaps. For defective Materials should undergo appropriate pretreatment such as burr removal and slitting to reduce the possibility of waste edge breakage.
