The difference between laser etching and traditional chemical etching

In the die-cutting process, there are several important factors: die-cutting materials, die-cutting equipment, die cutter and die-cutting process. These factors play a vital role in the goodness of the final product. They are like the four legs of a table. If any one of the legs is wrong, the table will be crooked.

Among these factors, die cutter is one of the factors that is very important. Today we will compare the difference between laser die cutting and etching die cutter!

Laser Die Cutting

Laser die cutting is a process in which a blade is processed into various necessary shapes using special equipment and placed into a mold in the gap between the laser-cut board and the PVC plywood. It is mainly used in mold industries such as printing, packaging and electronic materials. Compared with traditional manual processing technology, laser die cutting has the following advantages:

(1) High efficiency: After laser die cutting, drawing becomes simple and can be designed directly on the computer using professional software without any description; it solves the problem of low efficiency of traditional manual drawing with a pen on a drawing board;

(2) High precision: Laser die cutting uses CNC fully automatic operation in the cutting process, with uniform cutting gap and high dimensional accuracy, which can reach 卤0.1, further meeting the needs of various electronic The cutting demand of materials has brought revolutionary changes to the cutting problem of electronic materials. The traditional manual cutting process produces large errors. Etching knife mold: Etching knife mold is exposed by bonding film and steel plate, and then developed and reinforced by etching machine, and the excess part is etched away. Finally, the engraving and milling machine is used to process the blade into shape, and then the surface is treated. The material used for etching knife mold is high carbon steel plate imported from Japan.

Etching die is a die developed after laser die cutting. It has high precision, high difficulty, seamless blade, smooth line break and high repeatability. It is mainly used in soft circuit board PFC, electronic film, polarizer, backlight, transparent film, refractive film, self-adhesive, Mylar film PET...

Etching die has the following advantages:

(1) Etching die has no interface, no interface problem, and the cutting surface of the cut product is smooth; there is no contact at the corner, and there is no burr at the corner of the cut product;

(2) The die is smooth and has no joints. The blade has good flatness, fast replacement and convenient mold adjustment, which saves materials and time consumed during testing;

(3) The etching knife mold has high dimensional accuracy, with a tolerance of up to 卤0.03; the minimum double knife position can reach 0.5mm; several identical products on the same mold have almost the same size; the same knife mold is repeatedly produced with extremely small errors;

(4) The blade height and angle are diversified. According to customer requirements, the blade can be up to 2.5mm, and the angle can reach 30-60 degrees according to different cutting materials;

(5) In the face of complex workpieces, high and low knives can be easily combined on the same mold, and full-cut, half-cut, toothed knife, fold line and other forming can be achieved at one time.

Comparison between laser die cutting and etching die cutting:

Etching die cutting

The finished product design has few restrictions: small angles and narrow gaps can still be formed, which is suitable for die cutting of electronic materials.

The knife surface is flat and can be replaced quickly, saving materials and time consumed during testing.

The same set of tools can simply combine high and low knives, and can also be formed at one time when facing complex workpieces, meeting the requirements of time and precision.

The same knife edge can change different angles to cope with various materials.

The seamless incision has good verticality and a smooth cutting surface, which is especially suitable for optical films.

Short mold adjustment time.

Several identical graphics on the same mold, the size is close to the same.

Laser die cutting

There are many restrictions on the finished product appearance design: it is used for workpieces with general low requirements.

The flatness of the knife surface is poor, and it is often necessary to adjust it with shims, which requires professional operation, time-consuming and consumables.

The combination of high and low knives is difficult to control.

There is only one angle, which cannot be changed.

There are seams on the cut.

The mold adjustment time is long.

Several identical graphics on the same mold have very different sizes.

The same knife is used repeatedly, resulting in large errors.
