Flat Die Making Technology (2)

Seven, indentation bottom mold production indentation bottom mold production are the following methods:
1. Hand-bonding bottom mold This is the earliest production method of the indentation bottom mold. It uses the stamped impressions of carbon paper on the bottom mold steel plate, and presses the printing position. The indentation bottom mold is low in efficiency, poor in accuracy, the traces that are pressed out are not sufficiently plump, and the number of indentations is small. This backward production method has already been eliminated several years ago in developed countries such as Europe and the United States. With the continuous development of new technologies, this method will eventually be eliminated in China.
2, using the bottom mold slotting machine to open the bottom mold This production process is to use the South bottom mold material hand-drawn or printed on the die-cutting machine line marks, and then use special indentation bottom mold slotting machine on the bottom mold material Slot milling cutters that require groove widths mill grooves, and the quality of the indentation bottom molds varies according to the operator's skill level; at the same time, the overall cost of production is higher, and now the use of this production process is also increasing. The less you have come.
3, fiber indentation bottom mold This method of processing the bottom mold material is selected fiber board, hard and durable materials, generally used in the die cutting of the long board, the production process is more complex, need to be made on a special computer bottom mold processing machine, the overall production cost High and poor adaptability.
4, steel bottom mold This production method is directly on the bottom die steel plate processed by electric groove, this method of processing steel mold has the advantage of excellent dimensional stability and mechanical strength, the disadvantage is that the process is complex and needs Expensive proprietary equipment, this method of production is the most expensive one in the bottom of the template production, in the extremely long version of the live, and is a single product die cutting, you can choose to have.
5, indentation die This way to use indentation molding indentation bottom template is the most simple and convenient way to make, do not need to purchase equipment or specifically to customize the bottom mold, through a simple operation on the bottom mold plate Produce neat and standard indentation bottom molds, and have strong durability and low price. It is suitable for different needs of short, medium and long plates. The method of making indentation bottom molds with indentation molds is used in the world for the bottom molds. The most widely used method is also a new method for rapid development and application in China in recent years. Here we describe in detail the selection and operation of the indentation molding bottom template.
Selection and operation of indentation mould bottom mould
1. The structure and model of the indentation mold indicate that the indentation mold is mainly composed of an indentation bottom mold, a positioning plastic strip, a strong bottom film, and a protective tape.
The model of the indentation mold is expressed by “groove depth×slot width”. 2. Common types of indentation molds The indentation molds can be divided into four different types according to the use location: standard type, ultra-narrow type, and unilateral stenosis. Type, even pit type.
Standard type - used for wide distances on both sides of the indentation line at work. This type number is common type.
Ultra-narrow - used to close the indentation line to the die cutter.
Unilateral stenosis type - used to close the indentation line and indentation line.
Pit type - used to match two or more indentation lines with a distance of 4mm or less.
3. Selection method of indentation die a) Selection of indentation model number in die-cutting jamming groove depth of indentation die = maximum jamming degree, indentation die groove width = paper thickness × 1.5 + indentation line thickness pressure Trace height = die cutter height - (paper thickness + 0.05-0.1mm)

When the die-cut cardboard is used, the indentation mold is selected from the reference table (high-speed die-cutting knife is 23.8mm as the standard)

Note: The above specifications are only recommended for use, among which □ is the preferred specification b) The model of the indentation die when the die-cutting corrugated paper is selected Indentation die groove depth = corrugated paper compaction thickness, indentation die groove width = corrugated paper compaction thickness × 2.0+ indentation line thickness, indentation line height = die cutter height - corrugated paper thickness after compaction
