Discussion on the Making Process of High Quality Carton Die-Cut

Third, die cutter and indentation line

After the cutting of the stencil is completed, the cutting knife and the indentation line should be installed according to the relative position of the die-cut carton. In order to ensure the quality of die-cutting, firstly, a good quality die-cutter and indentation line should be selected. First of all, the die cutter is introduced. The thickness of the die cutter used in the carton is 0.71mm and the height is 23.8mm. The hardness is soft, medium hard, and hard.

Die cutters can be divided into soft and hard knives according to their hardness. Soft knives do not refer to soft blades, but die cutters use a lower hardness HRC35, which is performed on the edge of soft knives or processed to a hardness. On the H-day C56, the software knife line can be bent out of a smaller arc and radius; the hardware knife refers to the overall hardness of the die-cutting knife to HRC45, and the blade body has a higher hardness as a whole. Die cutting knife according to the shape of the edge, commonly used standard knife and double peak knife. For paperboards with a die-cut thickness of more than 0.5mm, we recommend the use of double-edge knives. This knives have two miter blades, which can effectively reduce the negative effects of the two convex surfaces, and the knife edge is extremely sharp and easy to cut into cardboard.

The indentation line is used to complete the indentation work of the carton folding on the die-cut plate. The thickness of the indentation line is commonly used 0.7mm, 1.42mm, 2.13mm, etc. The height of the indentation line is 22mm~23. 8mm. The selection principle of the indentation line is that the thickness of the indentation line is greater than the thickness of the paper; the height of the indentation line is equal to the height of the die cutter minus the thickness of the paper minus 0.05 mm to 0.1 mm.

The above brief introduction to die cutters or indentation lines is given below. The following describes the installation of die cutters and indentation lines and related processing equipment. The installation of the die cutter and the indentation line firstly cuts and bends the die cutter and the indentation line to the corresponding length and shape according to the length of each box type cutter line. The special equipments that can be used to process die cutters and indentation lines include blade trimmers, blade forming machines (bending cutters), blade punching machines (blade cutters), blade cutters, and the like.

The blade cutting machine is used for cutting the die cutter and the indentation line. Firstly, the length of the steel wire required on the die cutting plate is measured. There is a stopper on the blade cutting machine to allow the length of the steel wire to be positioned. After the specified position is good, all steel wires of the same length on the die-cut version are required to be cut at one time, and the length of the second section is taken again to re-define the specified position, which can effectively improve work efficiency.

The blade shaper (blade cutter) is used to accurately shape the arc or angle of a die cutter or indentation line on a die plate. Each device has a special die forming a variety of commonly used arcs and angles to bend the knife line, the formation position and bending degree of the knife line have corresponding rules for positioning, can guarantee the same arc in the same layout and The versatility of the angle makes operation easier and faster.

Blade punch (cross-bridge cutter) is used to pass the die cutter or indentation line on the die-cut board; , can ensure the smooth loading.

When the cutter cutter is used to make the die-cutting plate, the vertical intersection of the two die cutters is due to the presence of the blade bevel at the edge of the transverse die cutter. If the vertical die cutter section is cut into a straight line, it will cause a vertical intersection where Phenomenon, knife cutting angle cutter is to solve the problem of cutting at the vertical intersection of the two die cutters. Through the cutting of the blade angle cutter, the cutting edge of the die cutter can automatically cut out a sharp corner, just as well as the transverse die cutting edge. The inclined surface of the mouth is relatively effective to cut off the vertical intersection of the two touching cutters.

In the above, the cutting line processing equipment for the die cutters and indentation lines, which are commonly used for die-cutting and indentation of carton boxes, is introduced. After the blades are cut and shaped well, the cut stencils must be placed on the platform during installation, and a section of the machined cutting lines should be advanced. With the part down, align the corresponding stencil position, hammer the upper edge with a special knife die, and insert the knife line into the stencil. It needs to be emphasized that the special tool die hammer or wooden hammer must be used to install the knife line. The head of the knife die hammer is made of high elastic rubber. When the cutting line is used, it can be ensured that the edge will not be damaged.
