How to improve the die cutting precision of the die-cutting processing factory?
- 2019-04-23-

The main part of the die-cutting processing factory is cutting. Now the die-cutting machine can cut a variety of materials, such as paper, adhesive tape, copper foil, aluminum foil, graphite, etc. The precision of die-cutting is related to many factors, such as blade material. , the blade making process, the use or preservation method, and the like.

Below we analyze in detail the following factors of precision die cutting:

1, the impact of the blade

One of the most critical parts in die-cutting is the blade. How long does it take to wear it, is it sharp? These will affect the precision of die-cutting, and even affect the efficiency of die-cutting. The material of the blade is the key. What kind of material blade is used for the precision of die-cutting, what material should be used. Steel is very good, it has high hardness and durability.

2, the quality of sharpening

The quality of the sharpening knife determines the use time of the blade. The good quality of the blade has a long service life, and the quality of the cut product is also high and the precision is also high. After we sharpen the knife, we must let it cool down in time. If we need it to be sharper, the knife edge is brighter and the brightness is higher, we can polish it carefully on the oil stone, usually at the knife edge. Apply some paraffin or soap to the parts, the blade will be more durable, the cut out will be more suitable, smoother, without burrs, if there is a paper pull on the cut edge, it means that the blade is replaced, or It is the grinding of the blade.


3, the angle of the blade and its model

The angle of the blade is required. The material we cut is different, and its angle is also different. When we cut, the angle of the blade is generally fixed. Few people will choose the appropriate blade according to the material of the cutting. Angle, this is actually very bad, it will make the die cutter easy to damage, and the quality of the cutting will be very poor, it will become very blunt in a short time, the material is different, the angle of the blade is not the same Similarly, the material of the paper seriously affects the blade. For example, when the paper is very thick and contains a lot of gray powder, or the material we cut is very hard, in this case, the blade becomes dull and fast, according to the cutting. Different materials, choose different angles of the blade.

These points will determine the service life of the die cutter. We should pay attention to the protection of the die cutter when die cutting.

How to improve the precision of die cutting? ?

The traditional die-cutting process is mainly through the machine up and down type, and the cutting is carried out. Nowadays, there are many kinds of die-cutting products, and the die-cutting process is also changing with each passing day. Then, how to better control the quality of the finished products?

We have summarized several factors; for your reference:

First: the quality of the die (the blade of the die)

The die used in the die-cutting process determines the size and precision of the die-cut product. Usually, the products we die-cut, if the die-cut material is a harder material, we need a sharper die. The precision of the knife edge is required to be 0.02mm, and the edge is not sharp. These will hinder the precision of die cutting. The sharpness of the die has a great effect, which affects the efficiency of die cutting.

Second: the precision of the die-cutting position

Usually, the most commonly used PFC double-sided tape is to be completed by the die-cutting process of the casing. The casing process is realized by the front punching sleeve, and the required product size is punched out. The waste of the hole is discharged through the machine. This process and its die-cutting master, if the accuracy of the set is not enough, the FPC double-sided tape will be cut out to produce a size edge (and the size of the two glues above is different) Bad.

Third: the material of the die-cut product (main material)

The material we die-cutting will also have a little influence on the precision of the die-cutting process. The foam materials we make are relatively soft. After the die-cutting process, the foam will rise. Larger, especially some TP type foam die-cutting, the sides of the product are relatively thin, which will affect the accuracy of die-cutting. The main control is that we are in the die-cutting mode. Reserve a certain range of dimensional tolerances, the inner frame goes down the line, the outer frame goes up the line, and the precision of the die cutting is controlled within the range accepted by the customer.


How to ensure the quality of die-cut products?

There are five main aspects to ensuring product quality:

● Raw materials

Die-cutting is the process of forming a specific shape of a part of a material according to a predetermined shape by precision machining, cutting, and combination. The importance of raw materials for the quality of die-cut products can be seen.

● equipment

If it is a one-size-fits-all product, the problem is not big. If two or more are matched, it is time to test your equipment for good or bad. Constant tension, its own micro-adjustment, tension compensation device, paper stability, and accurate positioning are all related to the quality of the product.

●Mold

The accuracy of the mold directly affects the dimensional accuracy of the product (taking into account the special die-cut material, the size should be properly scaled according to the design and die-cutting experience).

●Process

The process is the method. According to the die-cutting process, the most reasonable die-cutting process is designed. The reasonable die-cutting process has a great influence on the product quality.

●Personnel

The processing of the products is the processing of the raw materials by the personnel using the equipment and the mold according to the process requirements. Experienced operators understand the machine's performance, are familiar with the materials, and strictly follow the process to produce qualified products.

If we are considering and implementing these aspects in the die-cutting operation, we believe that the precision of the die-cutting processing factory will definitely improve. What do you say?
