Principle And Die-molding Process Of The Production - India, The Molded - Printing Industry

Printing Molded products processed mainly refers to

, based on yin and yang mold, by mechanical pressure applied to some, so print is processed into the required shape or surface of a special effects of its special technology. By the process used in the mold and the final effect of different processing generally can be divided into two uneven indentation imprint and cutting technology.

Bump indentation technique is the use of the corresponding two yin, yang template, through pressure, in print embossed into a three dimensional surface relief-like pattern, the processing effect is a certain deformation of the surface of printed matter.

Indentation technique is the use of cutting blades, and steel wire arranged in the template, under pressure, will be printed rolling cut type of technology, the processing result is: both printed surface deformation, another fracture.

With the resulting development and continuous improvement of people's living standards, people goods, in addition to quality, the right product Package Requirements also increased. Molding process technology with its unique advantages, more and more widely applied in processing various types of printed surface to become non-print surface finishing technology is a little.

I. Principle of molding process 1. Molded Dimensions Proved, when the paper thickness increased, the shear stress reduction; the other hand, shear stress increased. In fact, in the case of changing the thickness of paper, play a major role not entirely the thickness of the paper, as well as molding the ratio of the size and thickness of paper, the variation of figure said:

Molding Size / molded thickness trend with shear stress

Note: 1,2,3,4 is printed with different thickness. Which 4> 3> 2> 1

2. Pressure In the molding process, because the processing of the image and the requirements are different, generally molded in advance calculated the force required to select and adjust the machine, and direct molding process. F1

mold pressure can be calculated: F1 = K * * A

The formula: F1-molded power needed, -molded in the shear stress per unit area, A-molding the actual separation of surface area, according to thickness and circumference considered as printed matter, K-molding process to consider the actual conditions and the coefficients of a series of technical factors.

Second, the production of Die Die-making, 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, makes up the template of the process operation. Die indentation production, quality assurance processed row knife key to quality.

1. System Plate Material (1) bottom plate materials include: Wood, PVC plate and sheet

board first asked board has a high hardness, resistant to pressure, be uniform wooden board, cut neatly, elastic consistency. Put on a knife, wire elastic uniform. Full page no stress, cutting out paper also force uniform, will not fracture, wear and tear on the knife small, extend the life of Die another board asked good flexibility, can ease due to bending Wood cutter is not appropriate due stress, subsequently better solid blade, the cutting, they have some cushion, so that the blade is more durable. Die for the production of wood with birch and beech. At present, Finland is the best quality wood board, wood, high hardness, good flexibility. System of good die-cutting quality. But it is expensive imported board, high quality requirements apply only to the die-board. Domestic product, the Shanghai board the best quality, homogeneous, Flexibility and the surface white. Northeast board of wood not uniform, it only applies to general Corrugated paper Box, the box of medium size, larger curve graphics and other products. Die manufacturing high quality plywood, and the template light weight. Therefore, common plywood floor boards, commonly used wood is 18mm, 15mm birch board. Cutting 18mm thick with general wood products, corrugated paper or sponge die-cutting products, is using 15mm thick wood. 20mm film and the wood used to make Adhesive Die products, commonly used version for the stripping of the boards 12mm or 8mm.

PVC plate thickness used 8mm, 5mm, 3mm, 3mm thick 18mm terms produced compound knife template, that is, the next two to 3mm plastic board, the middle layer of the 12mm board, three were chopped Position rivet after rivet with a knife on another line installed. As cutting costs, difficult installation knife, resulting in higher costs than wood cutting version, together with PVC plastic plate in the cutting will release toxic gases, metal parts of equipment and the human body are certain hazards, not suitable for promotion.

plate easy to cut thick steel plate and steel plate and high cost it is also used for the production of composite die-board. That is two layers of thin steel plate, 3mm thick, the middle is 12mm thick wood, while the cost of return, but made of die-strong, durable, can live many times tool changer version for flowers, because the long term change knife, the cost could be reduced, because of cutting quality, I can do with it.

Die-life depends on the ATC frequency, and the durability of different bottom plate is different.

(2) used knives, wire steel wire: Steel wire indentation in the cutting process used to do with the indentation line. A round mouth lines and lines of two fast mouth. High-23mm, thickness 0.7mm.

steel knife: steel knife cutting at the cutting line with indentation used to do. Steel knife is divided into single port, double-sided mouth and other specifications, the general high-23.8mm, thickness 0.7mm. Used knives, wire Sweden, Austria, Japanese products, to meet the processing of various types of die cutting products, steel knife are made of hard, medium hard, soft of three. Rigid blades, the hardness and high wear resistance, but little flexibility, forming bending is small, it is suitable for processing large, thick cardboard the shape of the simpler products processing; soft blades, low hardness, but good elasticity, forming curvature can be large, so is suitable for processing small quantities, paper thin, the shape of complex products; the hardness of steel knife is in between. Voltage

steel knife to cut the length of the small mosaic is appropriate, and generally not appropriate to conduct post-molding Voltage cut; the shaped steel knife steel wire, the knife edge and the bottom should be perpendicular to the wire to keep the steel knife blade I extend the line every point in the same plane.

(3) sticky rubber plug: its main steel knife edge on both sides of the template, using rubber elastic restoring force of effect, can be cutting edge after the separation of cardboard from the Department of launch. Its original height is 7mm, the rubber should be higher than the knife-edge 3mm ~ 5mm.

Shown: Stick diagram of a rubber plug, air liner material 2, 3 steel knife, rubber

Rubber generally synthetic polymer materials, elastic into hard, soft and neutral of three, use should be reasonable under the circumstances used.
