Performance analysis of quick installed creasing matrix and resin bottom mold

If you use the quick installed creasing matrix, you can ask the auxiliary workers to cut the quick installed creasing matrix in the spare time before the last order is completed. When the order is relatively stable, you can always consider to ensure that there is a spare set of quick installed creasing matrix. matrix, so as to avoid the time delay caused by shearing and creasing matrix.

The development of the materials used in the flat die cutting creasing bottom mold has gone through five stages, namely “manual interlining”, “hand stitching”, “quick loading cresing matrix”, “resin bottom mold” and “steel bottom mold”. “. Among them, the “intermediate line” and “joint line” methods use cardboard that matches the thickness of the printed product, and manually dig or splicing grooves with the required thickness and width. Because the creasing quality in this way is extremely unstable, this way is only reserved for die cutting relatively rough products, and is no longer used in the more demanding cigarette pack die cutting; and the “steel bottom die” is generally The current penetration rate is still not high due to the high cost and high risk when used together with steel knife molds or resin knife molds.

Quick install creasing matrix and resin base

Integrate all the quick loading creasing matrices to be used for die cutting single gang cigarette packs on a resin plate, which constitutes a resin bottom mold; After being divided into several parts and canceling the non functional connection between each creasing strip, it becomes several ordinary creasing matrices. Therefore, in the main part of the creasing trunking, the effect and accuracy of the quick installed creasing matrix and the resin bottom mold are not much different.

Comparison and Analysis of Processing between Ceasing Matrix Interface and Endpoint

Since the resin bottom mold is based on the actual process size of the printed product, a professional machine is used to engrave and process a groove on an integral resin plate, so the processing at both ends of the increasing matrix is ​​more rounded and in place, and the interface between different increasing matrices The connection is also relatively complete and stable. The quick installed creasing matrix is ​​spliced ​​by a single “straight line”, and the connection between the different creasing matrices is not as compact as the resin bottom mold. In actual operation, it often depends on the proficiency of technicians and the difference in handling methods. And there is a certain gap, which directly affects the appearance of the cresing line.

In addition, when using the quick loading increasing matrix, it is necessary to trim both ends of the quick loading increasing matrix and the increasing matrix inside the glue position before die cutting. Therefore, in terms of appearance effect and operation difficulty, the resin bottom mold is better than the quick loading creasing matrix. But as long as the operator’s technical proficiency is in place, the effect of the interface and the endpoint is not very different. The customer’s requirements for the product creasing line are mainly uniform and straight, full and easy to fold, not bursting the line and color, and there is no high requirement for the details of the interface connection.

The raw materials used in the resin bottom molds produced by different manufacturers are the same, that is, synthetic resin, while the raw materials used in the quick loading creasing matrix are relatively diverse.

(1) Relatively speaking, the paper quick loading creasing matrix of the same specification has the best softness and is easy to trim. If there is a double sheet, the creasing groove will become thicker obviously. Depending on the paper material, there will be obvious wear and tear, the cresing is not full enough, and even the length of the creasing line is shortened.

(2) The lines extruded by the plastic quick loading creasing matrix are the fullest and have the longest service life. Under normal circumstances, 500,000 prints will not show obvious wear. Even if there are many double sheets in the production process, the creasing slot will not be significantly wider. However, when it is used for creasing printed products with poor paper quality, it is prone to bursting and color bursting, and because the material of the plastic quick loading creasing matrix is hard, the trimming process is relatively difficult.

(3) The resin bottom mold has moderate performance in terms of durability and deformation resistance.
