Logo Printing Magnetic Closure Box The overall process flow and knowledge of post-printing die cutting indentation

Logo Printing Magnetic Closure Box die-cutting indentation is a special process in post-press processing, mainly according to the design requirements to consider whether to apply. This paper mainly from the definition of die cutting indentation, die cutting indentation plate and die cutting indentation production process of several aspects, roughly introduced the overall process of die cutting indentation.

What is a die - cut indentation?

Die cutting indentation process is according to the design requirements, make the edge of color printed matter into various shapes, or add a special artistic effect on the printed matter, and achieve a certain use function. With steel knife arrangement die (or with steel plate engraving die), in the die cutting machine the substrate punch cut into a certain shape of the process called die cutting process; The use of steel wire through the imprint, imprint on the substrate or leave a groove mark for bending process called indentation process.

What is a die - cut indentation plate?

Die cutting plate, in fact, is a steel wire edge, its height is about 23.8mm, the steel wire on the fixture bent into a variety of required shape, and then arranged in a "plate". By embossing, the substrate is cut into the desired shape. The indentation plate is also a steel line, the height is slightly lower than the die cutting knife line (about 0.8mm lower), there is no edge, the row of "plate" after the imprint, the substrate surface traces. There are special requirements for seamless cutting tools, is made of whole steel, the cost of this tool is higher, but durable.

Die - cut indentation plate of the bottom plate there are several?

The production of die cutting indentation printing plate to do a good job of the bottom plate, and then the network cable according to the requirements of the knife bending, discharge in the bottom plate, the bottom plate has two kinds of metal bottom plate and wood bottom plate.

(1) metal plate. The metal base plate has lead space typesetting, cast plate, steel plate engraving, plate engraving and so on. Lead - space layout is the layout of lead - space groups of different sizes. The cast lead plate is made of molten lead alloy. In this method, the steel wire is first bent into the desired shape, with a 10mm edge around it, and the outer edge is fixed with a wooden strip. Then the molten lead alloy liquid pouring in, after cooling, it becomes a die cutting knife version. Steel engraving plate is the first steel belt bent into a similar curve and die cut mark closed frame, joint welding firm, both sides of the ground into about 30mm height. Then accurately planed the frame line of the cut figure, according to the line will file out the knife edge, and finally heat treatment made die cutting plate. This die-cutting production is difficult, the process is more complex. Steel plate engraving plate is generally selected slightly larger than the printed text and text, thickness of 25mm steel plate, the need to be processed on the side of the grinding process, and then coated with photographic solution, sun. The text and text required beyond the edge line to milling, and then carved out the edge, the final heat treatment. This type of die cutting knife version although the cost is very high, but can be used repeatedly for a long time, generally suitable for small and complex shape products. At present, lead space typesetting is mostly used.

(2) board bottom version. Board bottom version of plywood, wood, zinc wood nail board and other several. Plywood is generally 9 to 13 layers with a thickness of 18 to 20mm. It is to transfer the design pattern to the plywood, in the line at the hole saw seam, and then the die cutting line and indentation line inlaid into the die cutting indentation plate. This method of die - cutting quality is higher, and die - cutting plate weight, shorter than the empty lead plate. Wood bottom plate is directly sawed into hard wood as a bottom plate. Zinc wood nail board is the die cutting pattern on the zinc board made negative figure, the zinc board nail to the board, after trimming embedded steel knife can be installed in the die cutting machine. Plywood is commonly used for the board bottom plate.

What is the production process of die - cutting indentation version?

Die cutting indentation version of the production, commonly known as row knife. The so-called row knife refers to the steel knife, steel wire, lining material according to the requirements of the requirements of die cutting indentation version of the process operation. At present, the domestic row knife operation basically uses metal empty lead and plywood two kinds of lining materials.

Gluing plate as a lining material template, first of all to make the bottom plate, other operations are basically the same.

(1) the manufacture of the bottom plate. It means that according to the design requirements of the product, a certain way is used to draw or draw the outline of the die on the bottom plate, and then through different process processing, saw out the narrow groove according to the outline. In the making of the bottom plate, the drawing of the die profile and the advantages and disadvantages of the sawing seam is the key to affect the quality of the plate. The making of the bottom plate, at first all by manual completion, the accuracy of the die completely depends on the individual technical level, must first draw the die on the board by hand and then use a wire saw along the graphic line saw seam; Has a laser plate-making system, in this system, the automation homework until the last working procedure, operation as long as the stay of die-cutting products shape size, paper thickness parameters enter electronic computer, electronic computer can control plate making system, make the floor according to the punching die graphics automatically move under the laser beam.

② Steel knife (line) guillotine cutting and molding processing. Steel knife (line) guilfer cutting and molding processing, refers to the design specifications and requirements, die cutting with steel knife, steel guilfer cut into the largest molding line segment, and then its processing into the required geometric shape process. When forming the knife, the choice of steel knife and steel line should be paid attention to. The rigid steel knife has high mechanical strength and poor elasticity. It should be used as a linear row knife as far as possible. Soft steel knife, good elasticity, try to be used as a large bending arc row knife. When choosing steel knife and steel line, the thickness of the material and the width of the indentation line should also be considered. The general rule is: the thickness of die-cutting products is different, the height and thickness of the steel line should be different, with the reduction of paper thickness, the height of the steel line increases, the thickness decreases.

(3) a knife. According TO the product design specification and shape, after drawing the specification sample and checking with the printed text and text, we can start the knife arrangement operation. According to the different lining materials used, the knife row operation is slightly different. The technical requirements and process difficulty of metal empty lead knife row are generally slightly higher than those of plywood empty material. When USING METAL EMPTY LEAD CUTTER, IT IS ACCORDING TO CERTAIN technological REQUIREMENTS, THE CUTTER shape is fixed directly in the specified position of the mold plate with empty lead to complete the cutter arrangement operation, which is very similar to the typesetting operation in movable type printing. In the metal empty lead row knife, the operator is required to be able to flexibly and correctly use all kinds of lining materials, and the printed plate can not be loose or strung in the die cutting process. Especially in the arrangement of all kinds of geometric figures, it is necessary to ensure that the figure is standard, and to ensure that the tightness is appropriate. A version of multiple maps, to be consistent with each other, not because of the empty lead ratio is different, and the difference. In addition, the vertical line of each point on the back plate of the knife should be equidistant, so as to facilitate clamping and fixing the knife. When USING THE PLYWOOD lining material TO ROW THE KNIFE, the steel knife and steel wire embedded in the bottom plate should be vertical with the plane of the bottom plate after sawing the seam, and the gap should be appropriate. There should be no deformation or twist in the embedding or processing. If the layout is composed of multiple base plates, the single base plate should be lined up and shaped first, then arranged one by one, and finally unified clamping and fixing. After the layout of the plate, the longitudinal and transverse lines to each other into a 90 degree Angle, the edge lines to be parallel to each other, so that the whole layout can be flat. In addition, the steel knife, steel wire interface should be discharged in the appropriate position, the interface gap should be appropriate, not due to pressure and overlap or gap too large phenomena.

(4) Check and fix knife. Fixed knife is also known as plate or card plate, is the layout of the plate card in the frame. After the tool arrangement is completed, do a comprehensive check again, and only after the check is correct can the tool fixing begin formally. Empty lead lining material plate fixing knife, to add wood around the frame, with solid lock directly fixed; With plywood as a lining material die cutting plate, should be according to the specific situation of the whole layout, add wood, fastened by the solid plate lock clamp.
