Selection technology of indentation strip mold used for different paper materials

with the continuous improvement of product packaging requirements in the commodity market, cartons and cartons, as the most widely used packaging products, should not only have exquisite printing and decoration, but also have perfect physical quality and compressive strength. The indentation bottom mold in the die-cutting indentation process is an important guarantee for the box quality. In addition to the secondary method of manually pasting the bottom mold, there are also the bottom mold produced by the bottom mold slotting machine, fiber indentation bottom mold and strip indentation bottom mold, etc

from a technical point of view, the indentation strip mold is highly respected for its simple and convenient operation, complete specifications and wide application range. It not only makes up for the shortcomings of the low relative position between the hand bonded bottom mold and the die-cutting plate, the low width and dimensional accuracy of the groove itself, and the short service life, but also reduces the overall cost of the carton. Whether in automatic die-cutting machine or semi-automatic die-cutting machine, indentation strip mold can have perfect performance

the indentation strip mold does not need the special equipment to machine the bottom mold, nor the expensive price of the fiber bottom mold, nor the quality problem of uneven box angle bending. The indentation depth is relatively stable, suitable for different paper types, and it is cheap and durable, suitable for different needs and uses. Even workers who have never done indentation strip mold can skillfully use it in a short time

the use method of indentation strip mold is simple and convenient. When using, first measure the length of the indentation line on the knife template, cut the indentation strip mold according to the measured length, and put the synchronous belt and reducer that locate the suction strip; In terms of force measurement, the electronic universal testing machine adopts the load sensor elastic opening card to cover the indentation line, tear off the protective adhesive, install the die-cutting plate, and then start the die-cutting machine once, and the indentation strip mold is positioned on the bottom die steel plate. Then tear off the positioning adhesive strip and complete the positioning of the indentation strip mold. Reinstall the bottom mold steel plate and start the die-cutting machine to carry out the die-cutting operation

there are many kinds of cartons with different shapes, and the paper of die-cutting color boxes is also different. For different box shapes and paper, different specifications of indentation strip mold must be applied

the specification of the indentation strip mold is: groove depth × Pit width, such as SLB type 0.44 × The specification of 1.3mm is: Standard indentation strip mold, the depth of the groove is 0.44mm, and the width of the groove is 1.3mm

in touch cutting indentation, different types of paper should use different specifications of indentation strip mold, in which cardboard and corrugated paper have different selection methods

selection of indentation strip mold during paper jam die cutting

first measure the thickness of the paper with a caliper. The thickness of the indentation line used for touch cutting should be greater than or equal to the thickness of the paper, and the groove depth of the indentation strip mold should be equal to the thickness of the paper. In production practice, the groove width of the indentation strip mold can be selected according to the following formula: indentation groove width = paper thickness × 1.5+ thickness of indentation line

for example: the thickness of the paperboard is 0.52mm, the thickness of the indentation line is 0.71mm, and the depth of the groove of the indentation strip mold =0.52mm (about 0.5mm). After calculation, the groove width of the indentation strip mold =0.52 × 1.5+0.71=1.49 mm (about 1.5 mm), then the model of indentation strip mold should be 0.5 × 1.5 mm。

selection of indentation strip mold during corrugated box die cutting

first measure the thickness of corrugated board after flattening, select the thickness of indentation line to be greater than or equal to the thickness of corrugated board flattening, and select the depth of groove to be equal to the thickness of corrugated board flattening. What we need to explain here is that if the thickness of the indentation line is less than the thickness of the cardboard, the indentation line is not prominent enough. When the carton is folded, it is easy to deform at the indentation line, and when it is serious, the cardboard will burst, which will eventually affect the beauty of the carton, although some regions have taken some targeted measures to control it. In addition, if the depth of the groove is less than the thickness of the cardboard, the same situation will occur; If the groove concentration is greater than the thickness of the paperboard, the situation will be better, but it is also easy to cause cracks in the parts connected by the indentation line. Therefore, in actual production, we usually calculate the width of indentation strip mold groove according to the following formula: indentation strip mold groove width corrugated board flattening thickness × 2 + thickness of indentation line

for example: the flattening thickness of corrugated board is 0.85 mm, the thickness of the indentation line is 1.0 mm, and the groove depth of the indentation strip mold =0.85 mm (about 0.8 mm). After calculation, the groove width of the indentation strip mold =0.85 × 2+1.0=2.7 mm (about 2.0mm), so the indentation strip mold model should be 0.8 mm × 2 . 0mm。

after making the choice of these two kinds of paper and indentation strip mold, maybe you are not very clear about this formula, and have some questions, why can't you choose the indentation strip mold used in corrugated cardboard for paperboard? Because there are great differences between the two:

1. If the corrugated paper indentation strip mold is selected for the paperboard, the product will have adverse effects, resulting in uneven expansion angle of the box, bending, insufficient compressive strength, and insufficient indentation lines, so that the product cannot be guaranteed

2. Due to the different paper thickness between the two, the width of the indentation strip mold of corrugated paper is significantly wider than that of the indentation strip mold of paperboard, while the indentation strip mold of paperboard is narrow. If the indentation strip mold of paperboard is selected for corrugated carton, the indentation line of the product will burst, the quality is poor, and in serious cases, the product will be scrapped, causing economic losses and customer outflows

for different paperboard, such as AB wave, EB wave, b wave, e wave, F wave, G wave, etc., you need to choose different indentation

strip mold

in the printing and packaging carton industry, die cutting is a crucial process and an indispensable department. Therefore, if you are not sure about die cutting and make semi-finished products, the cost will be greatly increased. The flexibility and convenient use performance of the indentation strip mold just adapt to the development trend of multiple varieties and different batches of cartons and cartons, which is favored by more and more carton and carton processing enterprises. It not only reduces the consumption of manpower and man hours in the production process, but also has high-quality fatigue testing machine for enterprises. It is a kind of precision instrument, fast service and quality for fatigue characteristics and fatigue life test of experimental materials, Provides a reliable guarantee
