Diagonal hot stamping process
The hot stamping process can improve the grade of the product and give the product high anti-counterfeiting performance. Therefore, it is applied more and more in the field of folding color box processing. However, since the electrochemical aluminum foil contains materials such as hot melt adhesive and film, the maximum application of the electrochemical aluminum foil is not only applicable. Saving material costs for enterprises, it is also advocating green for the industry and the country. Positive response to the printing policy.
The traditional hot stamping process is as follows: the electroless aluminum is heated by the hot stamping Plate, the peeling layer and the adhesive layer are successively melted, and the adhesive layer is bonded to the substrate under the action of pressure, the colored layer is separated from the base layer of the polyester sheet, and the aluminum layer is The colored layer remains on the substrate to complete the hot stamping. In the traditional hot stamping process, the choice of the width of the electrochemical aluminum foil mainly considers three factors: 1 The width of the electrochemical aluminum foil is 6~12mm wider than that of the hot foil pattern, so as to ensure that the shaking of the electrochemical aluminum foil during the hot stamping process will not cause the defective stamping; 2 units The area is stamped as much as possible to maximize the saving of the electrochemical aluminum foil; 3 The narrowest specification of the electrochemical aluminum foil is limited to 25mm to ensure the stability of the tensioning operation and avoid folding and gold breaking. In the conventional hot stamping process, the conventional electrified aluminum foil method is horizontal or vertical straight pull, and the width of the electrochemical aluminum foil is generally 25 mm, so in the case of a small hot stamping pattern, the horizontal or vertical straight pull type of electrochemical aluminum foil The utilization rate is low, because only a part of the middle of the electrochemical aluminum foil is used, and a large part of the electrochemical aluminum foil on both sides is wasted.
The use of the diagonal pull stamping process can solve the above problems well. The process of the oblique pull stamping process is:
(1) It can be judged whether the shape of the pattern to be stamped can be used in a diagonal pull mode. The judgment standard is: when the width of the pattern to be stamped is less than 20 mm, and the number of hot stamping patterns in the same column after the typesetting is n (n ≥ 2).
(2) Calculate the diagonal pull angle: set the interval between two adjacent hot stamping positions to be a, the hot stamping position width is b, the length is c, and the interval of hot stamping marks on the electrochemical aluminum foil is d, which is calculated according to the formula θ. Pull out the angle θ, and then determine the position of the electrochemical aluminum foil in combination with the size of the bronzing machine, and set the jump step to c+1mm.
(3) It is determined that the width of the electrochemical aluminum foil is nb+(b-1)+6 mm, and the anodized aluminum foil is obliquely stamped according to the diagonal pulling angle θ.
It is worth mentioning that when the product needs to be stamped with multiple different patterns, it must be noted whether the gap between different pieces of electrochemical aluminum foil is sufficient (≥1.5mm), and whether the diagonally pulled electrochemical aluminum foil overlaps with other straight-drawn electrochemical aluminum foil, if If there is overlap, the diagonal pull mode cannot be used.
Take a folding box order of 10,000 boxes as an example, the typesetting is 6 units in the horizontal direction and 3 units in the vertical direction, totaling 18 impositions. If the vertical straight-drawing hot stamping process is adopted, it is necessary to use 108 rolls of anodized aluminum foil with a size of 25mm×1200m; if the oblique-drawing hot stamping process is adopted, only 36 rolls of anodized aluminum foil with a size of 25mm×1200m are required, and each production is 10,000 boxes of color. The box can save 72 volumes of anodized aluminum foil. Due to the different hot stamping patterns and hot stamping positions of different products, the amount of electrochemical aluminum foil is also different. Even with a simple double-row diagonal pulling method, the saving of electrochemical aluminum foil can reach more than 30%. Therefore, the use of the diagonal pull stamping process can greatly save the electrochemical aluminum foil, greatly reducing the production cost.
