Die indentation is in a special finishing process, mainly based on the design requirements to consider the application. In this paper, the definition of indentation from the die cutting, die cutting and die-cutting plates indentation indentation several aspects of the production process, cutting a rough introduction to the whole indentation process.
What is a die indentation? Die indentation technique is based on design requirements, so that the edge of color printing for a variety of shapes, or printed on the increase in the types of special artistic effects, and to a use function. Lined with steel knife mold (or into a mold with a steel sculpture), the cutting machine to cut to the shape of substrate impulse process is called cutting process; the use of steel wire through the imprint, the traces of substrate by pressure or conducive to bending of the groove marks left in the process known as the indentation process.
What is the indentation of the plate cutting?
Die plate used was actually the mouth of steel with a front line, its height is about 23.8mm, the steel wire bent in the fixture on a variety of shapes needed, and then arranged in groups, "plate" . After embossing, so that substrates cut into the shape required. Indentation plate used is steel wire, high wire than the cutting knife with slightly lower (by about 0.8mm), no front items and exclusive form a "plate" with the impression after, to mark the surface of substrates. Empty-seamless special tools required, is made of single piece of steel, the higher the cost of such a tool, but durable.
Indentation of the bottom plate cutting plates are there?
Make cutting indentation plate with first and bottom plate, then the required cable type knife bending is good, emissions in the bottom plate, the bottom plate of wood with metal bottom plate and bottom plate of two.
metal bottom plate. Layout metal bottom plate of a lead air, pouring stereotype, steel-based lithography, plate lithography and so on. Lead space layout is an empty set of different sizes arranged in sections of lead. Casting stereotype is cast molten lead alloy liquid bottom plate. This method is first steel wire bent into the shape required, to stay out of 10mm around the edge of the external fixation with wood. Then pouring the molten lead alloy into the liquid, the cooling was turned into a cutting knife version. Type of steel bent steel engraved version is the first curve with cutting marks almost closed boxes, solid welded joints, two grind about 30mm high. And accurately under the cut plane graph border, filed by line will cut out, made of die-final heat treatment. This die-making difficult, complicated process. Steel engraved version is generally used in printed pieces slightly larger than the illustrations, the thickness of 25mm steel plate, the processing side grinding of need, and then coating photosensitive liquid, Fanshai. Graphic knife will need to go beyond the line of site milling, and then carving knife out of the final heat treatment. Although cutting knife version of this costly, but the long term repeated use, generally suitable for small and complex shaped graphics products. More use of lead in air current layout.
wooden bottom plate. Wood bottom plate of plywood, wood, zinc and several wooden boards nailed together. Plywood is generally 9 to 13 layers, thickness 18 ~ 20mm. It is to transfer designs to the plywood, drill holes in the line Department saw kerf, then cutting knife embedded into the line and the crease line made of die indentation plate. High quality die this way, and die-light weight, compared with an empty row of knives lead plate between the short. Sawn wood bottom plate that is molded directly to the hard wood as the bottom plate. Zinc the nailing of wood together is to design cutting boards made of zinc overcast map to zinc plates nailed to the board, by inserting a steel knife after trimming can be installed in the die-cutting machines. Wood bottom plate is commonly used plywood.
Die indentation What version of the production process?
Die indentation plates, commonly known as Pai knife. The so-called row refers to the steel knife blade, steel wire, lining materials in accordance with the requirements space, fight the composition of die indentation version of the current process operation, the basic operation of the domestic arrangements of metal air knife lead and two plywood lining air material.
Laminated version of the template materials for lining air, making the first floor to the other of the same operation.
