Postpress Technology - Magnetic Die indentation


Thickness of the size; A separation surface is the actual die area of ​​indentation, according to material thickness and cutting to calculate the circumference; K indentation process to consider the actual cutting conditions and various technical factors affecting the coefficient,[link widoczny dla zalogowanych], K value in the range between 0.76 and 1.34. Indentation in the actual cutting production, usually first with the press in the test material per unit length of the test method to determine the cutting force F on the value, and then calculate the size of die-cutting pressure, that the average cutting force per unit length F = P1 / l. Cutting pressure required: P: K1 · L · F above formula: P is cutting pressure; L to die around the length (including the line incision and pressure); F for the unit length of the die cutting and creasing force; K1 to consider the actual production of the coefficient of various unfavorable factors, taking K1: 1.2 ~ 1.3. Cutting pressure while also cutting the size of the rate of indentation,[link widoczny dla zalogowanych], whereas the cutting speed of indentation is a direct impact on productivity of cutting process factors, general molding speed increases, power will die JK Ding increased. Cut through and through the die _ JJ Fu printed version. 3 version of the production of magnetic cutting knife point method and attention to cutting knife Edition can take advantage of government constraints of chemical and mechanical methods to produce carved program. This method is the use of pieces of computer typeset version of the El in the cutting knife stuck parts of chemical Lin Luan loss to a certain degree of etching,[link widoczny dla zalogowanych], and then on the cutting tool for machining version until meets the requirement until the final post- treatment processes, such as nickel, chrome, carburized and laser treatment. Cutting knife in the production version to note that the three basic parameters: cutting angle, height and floor thickness. The choice of cutting an angle of the die according to the type of material, such as that sold to a paper type, mode Qieding Ding larger version of the module should be selected if the film ridicule deer horn-like material and Recovering materials should be selected more black mold small angle, generally should be controlled either 30 ¨ ~ 11O high floor to determine the thickness of the River. In the case of W under the high for the 0.44him. bottom pull thickness between the 012-014nml. die-cutting process can be divided in accordance with universal, enhanced and laser-based general-purpose J line hardness minimum. reinforced better. The use of laser cutting production version of the J line U hardness maximum. of cutting the f} 1 with fierce known a lot of life, such as cross-cutting pressure, material type, texture. touch cutting requirements (or current through the semi} knife cut through), ink, machine status and operation of I week trial personnel. it is difficult to determine the specific mode diced] line is much resistance to cutting rates, only in accordance with international circumstances quite OK. 4, magnetic characteristics of magnetic bandits die cutting technology and other cutting pressure indentation call technical characteristics than many of its own. advantages: (1) strong adsorption of magnetic force of the magnetic roller fire. can be higher the speed of cutting. (2) very high precision magnetic roller, concentricity error can be controlled within 2m blighted land. (3) lines installed by positioning cutting knife version. disassemble the small version is very easy to die 7 (4). flexible and widely used, especially for varieties of the same size but the number of cases of fancy. (5) According to the die-cutting demands of different cutting materials can be produced by processes not I. IDnZ knife take refuge, to cut costs. (6) cutting Diao version of the high precision level is good. knife version height error can be controlled in 3.11. (7) can be processed to any pattern and point D] line, the different cross-section height, base Disadvantages: (1) The cutting 『J Version by, J Majesty the high and magnetic roller gap deaf IiI I lack the shoulder system, the blade wear and tear - not like grinding. The overall style imprinted roller grinding usually 3-5 times. (2) magnetic mode earnest River Gui-not appropriate volume,[link widoczny dla zalogowanych], single Ding single, but more suitable for small-volume, multi-die processing orders of products. IV. Conclusion With the economic development. People of packaging materials and printed materials have become increasingly demanding of health standards The more rice and more concerned about the health package, it adopted J = f_I non-toxic environmentally friendly water-based ink frHilil proportion is increasing. Although the magnetic clutch {; IJ's use of technology in China for less than high, but with the Flexible 17lll ~ ilbL cases more and more. mining J_ 『J imprison die cutting technology will more and more. and round Lian die cutting technology will further expand the magnetic brush cutting technology should, in particular, Double-Twin-cut is the r success. Nan this believe in the near future. Magnetic die-cutting technology must lock the domain in the country has been tremendous development. China Packaging 2005/591
