Development Tendency of Milling Machine

The development of heavy duty machine tools will present two big trends. On the one hand, is a large flexible manufacturing technology with machining center or unit, large combined compound machine tool for the development direction, among them, horizontal boring and milling machines will be gradually replaced by the high speed machining center and flexible manufacturing unit. Floor-type milling and boring machine is given priority to with development of large combined compound machining center, with two or more variegated host compound machine tools, to meet the large processing parts sheet small batch production, technology is complex, the auxiliary time, and the characteristics of the processing cycle is long, often by a process, it is difficult to complete all the machine and the two combined machining center was completely can be achieved. Such as: two compound machining center cnc milling machine, and the sharing of lathe bed and guide rail, respectively, with a rectangular table and a rotary table (index), can be boring and milling processing; A floor-type milling and boring machine with a large compound machining center CNC single column vertical lathe, common lathe bed guide rail, a landing platform and a rotary table, can complete car, boring, milling, drilling and other processing, rotary table can be divided into degrees. There are two large ground Shared bedway milling and boring machine, and other combinations. Which save area, reduce the cost, also improve the machining efficiency. Another trend is the pursuit of refinement, improve the technological content of equipment manufacturing, reflect the characteristics of the machine safety, environmental protection and human.

Above all, contemporary horizontal boring and milling machine and floor type milling and boring machine technology is developing very fast, mainly reflected in the updated design concept and machine speed and manufacturing process level has greatly improved, on the other hand is a machine tool structure change is big, the application of new technology. Horizontal boring and milling machine structure to develop in the direction of high speed motorized spindle, floor-type milling and boring machine to the pillow (not boring axis) structure direction, attachment is high speed, multi-axis linkage function, the structural type of diversified development trend, this will be the new trend of developing the technology for a period of time to come.

The Process Principle of Offset Printing

"Offset printing" and "lithography" is one meaning. This kind of printing method is through the drum colloid impression touch the glue on the surface of the ink transfer to the paper. Due to the plastic surface is flat, without concave decorative pattern, so the design of printed on paper and decorative pattern is flat, poor stereo feeling, antifalsification is poor. Required for offset printing ink is less, mould manufacturing cost is lower than the gravure.
Also known as Offset printing (Offset), Is a kind of lithography, can restore the original color, contrast and level of the original pattern clearly with high precision, is by far the most common method of paper printing. Applicable to poster, profile, instruction, paper, packaging, books, magazines, calendars, and other relevant color print.

Offset Printing Process Principle
Offset printing is the color theory as the center, using the latest achievements of science and technology, using industrial mass production, copy of the original pattern system engineering. In the process of printing process, From the review of the original pattern, process design to each of the plate making, printing process, process parameters must be determined strictly, directly involved in printing colour information transmission of psychological evaluation and quantitative detection.
Distinguish between "gravure" and "offset", see the colors and stereo feeling of decorative pattern can determine. If the two bill to contrast, the difference is very obvious, it is easy to judge. In addition to a beginner, also can use the following two methods: the first is a "touch". Gravure RMB frontal "The people's bank of China" six words, the feeling of bulging is very obvious, as long as the fingers touched gently from left to right, can clearly feel that every word is raised. The second is "the edge". Gravure printing of text and pattern, line edge will be a spreading of ink caused by tiny "burr", use a magnifying glass can see very clear. And offset printing the line edge is smooth.
The selective adsorption principle of plate
Branches in assaying principle; Indirect printing principle; Principle of oil and water should not be.

Item Details of Flexible Food Packaging

Success of food packaging besides through the use of modelling, colour, pattern, material cause consumer attention and interest from the product, but to produce consumer products packaging accurate understanding. If you are to get is not the aim of the packaging, but packaging products. Accurately convey the item facts are truly essentially the most efficient way to show product image, can be employed in a very completely transparent packaging, can open the window to demonstrate the goods inside packaging container, graphics might be drawn on food packging products, are capable of doing it within the packaging concise text, pictures may be printed for the packaging color products, etc.

Accurately convey the product or service information, also requires the class on the packaging and also the grade of the product, cover or exaggerate the quality of the goods flexible packaging, function is failure. Our export ginseng used sacks, cartons, foreign suspect is dried turnip, natural understanding from the rough packing grade.
Instead, low-end products with colorful expensive packaging, also won't fascinate consumers. At the moment our country most of the small food packaging and printing in the marketplace is quite exquisite, eye-catching color, gorgeous pattern and silver flashes of aluminum foil pouch with instructions, for consumers, there exists a huge temptation, especially children, most of that time period the meals value and price of bag is far, result in the person feel cheated, so, the standard of the packaging has to be adapted for the grade from the product.
