The choice of birthday gift packing box embossing process!

1. Ensure that the quality of the birthday gift packing box indentation is not affected by.

When setting the birthday gift packing box indentation position, based on the front end of the birthday gift packing box process selection, design the birthday gift packing box indentation area size and depth, but also according to the anti-breakage indicators, as well as the weight of the loaded items to determine the four corners of eight sides or four corners of four sides. In terms of die-cutting width, birthday gift packing box layout should be as small as possible, the layout is too large or multi-pieced, easy to die-cutting pressure adjustment difficulties, to completely level the layout, there are certain technical difficulties. Therefore, a reasonable arrangement to ensure that the quality of birthday gift packing box embossing is not affected.

2. determine the birthday gift packing box grey board card using the process.

Then, determine the birthday gift packing box grey board card using full penetration process, half penetration process, or single side indentation process, double side indentation process, confirm and then audit the data, design birthday gift packing box indentation iron block height. The height of the iron block must be calculated according to the relevant data of birthday gift packing box, the calculation method is: the height of the knife bar 23.8mm minus the thickness of the grey board card, plus the thickness of birthday gift packing box package material and tape thickness, the calculation formula: T = D - H + B + J. Which, T = iron block height, D = knife bar height, H = grey board card thickness, B = package material thickness, J = tape thickness. For example, choose a thickness of 2mm grey board card; quantitative 157g/m2 coated paper, its thickness is 0.17mm; tape thickness is 0.04mm. according to the formula can be obtained, the iron block height = 23.8-2 + 0.17 + 0.04 = 22.01mm.

The value obtained above is the birthday gift packing box indentation iron block height, but because the birthday gift packing box selected materials are different, H and B for variable values, so according to the birthday gift packing box different materials to calculate the height of the iron block, choose the birthday gift packing box gray plate card molding paste way, decide the birthday gift packing box indentation depth and location. Careful planning and evaluation, the production process can be accurate, the four sides of the die-cutting will not appear not through, burrs and other defects, laminated birthday gift packing box box surface can be flat and perfect.

3. birthday gift packing box embossed knife drawing requirements

According to the birthday gift packing box embossing process design requirements to draw the embossing knife plate, in addition to the birthday gift packing box specification size, iron block position, height is also very important.

First, according to the formula T = D - H + B + J to calculate the height of the iron block, to confirm the birthday gift packing box embossing position, and according to the birthday gift packing box after forming the box body four corners to decide with ordinary tape or cloth-based adhesive fixed. In addition, the thickness of the birthday gift packing box wrapping material should also be calculated, these factors are an important basis for calculating the indentation object.

Then, according to the birthday gift packing box design requirements, the position dimensions and the height of the iron block are marked with grey lines in the birthday gift packing box cutter layout. The same area of iron, not only height, but also size, small iron is often higher than large iron, in a stepped juxtaposition, if necessary to make a detailed description (as shown in Figure 1). These marking data is the important basis for the production of birthday gift packing box knife plate, any omission may cause the knife plate production failure.

4. birthday gift packing box all-through process

birthday gift packing box structure, appearance design is very different, the process is long and tedious, one of the most important is birthday gift packing box die-cutting, birthday gift packing box die-cutting and divided into full penetration and half penetration. The birthday gift packing box die-cutting process is suitable for most grey card die-cutting. When applied to birthday gift packing box embossed products, the full penetration of the die-cutting and embossing process can be carried out simultaneously, the operation of the die-cutting pressure requirements are very demanding, both to completely cut off all four sides, but also to ensure that the embossing depth of birthday gift packing box meet the process requirements. Pressure is too large, indentation depth exceeds the standard, birthday gift packing box laminated surface will appear depression; pressure is too light, birthday gift packing box gray board card four sides can not be completely cut off, the phenomenon of even paper, clear waste will also appear broken skin and other undesirable problems.

Therefore, birthday gift packing box all-through process in adjusting the pressure, to adjust the knife line first, all to meet quality standards, and then the birthday gift packing box indentation of the iron block to adjust.

5. Confirm the actual birthday gift packing box depression depth.

Under the same pressure, the thickness of the iron block at the bottom of the bday gift packing box indentation is subsidised one at a time to make its iron surface higher. After several adjustments, then test pressure, followed by calipers to measure the actual birthday gift packing box depression depth of grey board card, while the four corners and eight sides are measured in turn, all meet the standard before production. birthday gift packing box production process, but also every 500 ~ 1000 sheets of inspection to ensure the consistency of batch quality. After all of this is completed, the box is then transferred to the birthday gift packing box V-grooving process, ready for grooving.
