Introduction to the relevant knowledge of the automatic leather shell machine
The fully automatic leather case machine focuses on the function of making leather case and hard paper case. The automatic cover machine adopts vacuum conversion system, automatic lubrication and oiling system, quick mold change system, intelligent control glue preheating device, and can automatically complete the operation of conventional book case cover gluing equipment, as well as double-sided cardboard, center strip or center paper positioning, edging, two-way leveling. It is also widely used in the manufacture of products, and it also largely satisfies the diversified thinking of investors, and can recover the investment cost in a short period of time.
The gravure printing process of the automatic leather case machine is divided into two steps, that is, the traditional gravure printing process is used to print the graphic on the film, and then the film with the pattern is laminated on the non-woven fabric through the lamination process. Generally, non-woven bags with large-area colorful patterns use this process. It is characterized by exquisite printing, full machine production and short production cycle. In addition, the fully automatic leather case machine has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. There are two kinds of thin film light and matt to choose from, and the matte has a frosted effect! The disadvantage is that it conflicts with the concept of environmental protection, because the film is difficult to degrade.
Fully automatic leather case machine heat transfer belongs to special printing! This method requires an intermediate medium, that is, first print the graphics on the heat transfer film or paper, and then transfer the pattern to the non-woven fabric through the heat transfer printing equipment . The commonly used medium for textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layered versions, comparable to photos. Suitable for small area color image printing. The disadvantage is that the price is high and the printing cost is high.
As we all know, the processing technology of gift box lids used in different packaging boxes is different, and the gift boxes that gift box lid machines can pack are also different. A good exquisite gift box usually packs some exquisite but expensive products, which can better highlight the temperament and level of the products. Of course, for some applicable and popular products, they can be packed in ordinary gift boxes.
The lid of the gift box is processed into a plate. Today's gift boxes are exquisite and beautiful, so the colors of the plates produced are also varied. Usually, a style of gift box not only has four basic colors, but also several colors, such as gold and silver, which are all spot colors.
The paper used for the cover processing process, the ordinary gift box wrapping paper uses double copper paper and dumb copper paper, and the weights are 125G, 105G, and 157G respectively. The wrapping paper of a small number of gift boxes will be more than 200G. Because the wrapping paper is too thick, the mounted gift box is prone to blisters and looks sluggish. Paper mounting is to choose the appropriate double gray paper according to the needs of customers, commonly known as gray cardboard or gray cardboard.
For the printing of the cover processing process, the gift box is only wrapped in printing paper, and the mounting paper will not be printed, and most of it will only be dyed. Because the gift is an outer packaging box, the printing process is very demanding, and color difference, ink dots, and bad editions are taboo, which will affect the appearance.
