In general, the basic dimensions of the tray are given by the customer, but in addition, the other parts of the size by printing factory in accordance with the circumstances of the paper width deputy, paper thickness and automatic packaging machines to determine. Among them, the most important thing is to set the size of the respective positions of the level of the line, if set properly, could affect the carton forming, plug not inserted into the tongue, locked buttoned live phenomenon. If these problems is the use of manual packaging, it may have little effect, but if it is on automatic packaging, the problem is big. Therefore, in each die-making must be based on the situation of the paper, carefully set the size of each location.
Currently die-making, handmade, laser cutter production. Handmade is the most primitive method of making templates, grooving, machetes and knives are mounted all done by hand, making influenced by subjective and objective factors, the error is so large die-size handmade, often uneven line knife straight, high and low income position is not accurate, so the die-die-cutting carton forming natural effect is not good. The current production methods has basically been eliminated, only some rough product (If the boxes, etc.) can be used. Laser cutter template is introduced in the early 1990s Daomo technology, laser grooving machine automatically machete. Because of its small by subjective factors, the production of high precision, small error, short production cycle and other reasons, is currently widely used in the market.
Unfortunately, whether by hand or laser Daomo Die, loaded knife still need to complete the hand, a laser knife stencil, after a reasonable selection tool and set the size of the line, put the knife has become the most critical link. A knife mounted technical personnel, experience and sense of responsibility has affected the quality of a knife version. In practice, we often encounter a new production of laser template knife than inadequate income position, the knife loose cable is received too large, the size of the problem of inconsistency in general this is mainly due to production staff inexperience or loaded knife work problems caused by the sense of responsibility. Therefore, to avoid this situation that the impact to the product quality and die work, in a new production of laser cutter template for the first time, we must carefully check the knife knife line edition on whether there is loose, play sample before mass production, carefully check each carton forming the subject, in particular the case of low bit line to close each position. Sure no problem and then no bulk die.
Further, when the die-making, should if too high, it will cause a "burst line auriventris" phenomenon based on a high degree of product selection of the appropriate paper knife line, the indentation of steel wire used, too short, in the indentation, paper fibers may not fully pressed through. Since the paper's own elasticity, when both sides of the tray molding and folded back, the opening will expand outward to form an opening bulge phenomenon. In addition, the choice of steel, steel wire, should be considered by the width and thickness of the die-cut products line indentation factor. General rule is: With the paper thickness decreases, the height of the steel wire is increased, reducing the thickness.
