The die-cutting processing factory is a processing technology whose principle is a process for processing products by means of punching and punching the products by means of punching. Traditionally, die cutting is a collective term for in-mold die cutting and indentation processes for printed packaging materials. With the continuous development and development of electronic products, die-cutting has been developed from the traditional sense of packaging and printing materials to the development of soft, high-precision products such as self-adhesive, foam, mesh, and conductive materials. The molding process is collectively referred to as die cutting.

The die-cutting processing plant has not only limited the development and specific position of the electronics or printing industry. The industry has developed to the present day. Any product that can use the flat or round-rolling tool for automatic punching and indentation molding is considered to belong to the die-cutting industry. product. The area involved is not just the electronic printing industry.

In production, we will encounter a wide range of die-cut products, but common die-cut products can be divided into the following categories according to their use and structure:

1. Glue: It is mainly used for pasting. The double-sided tape is die-cut into the desired shape according to customer requirements. The general form is face paper + glue + bottom paper. Under normal circumstances, the face paper has a single handle with the same shape and glue; there is a single sheet without a handle, the shape is larger than the shape of the glue; and the whole sheet of paper directly and the bottom paper sandwich the glue in the middle Both the paper and the backing paper are separated, and the material is paper or PET. The release force is selected according to customer requirements.

2, glue + mesh die-cutting class: mainly plays the role of dustproof and waterproof. The mesh is die-cut into the desired shape, and the double-sided adhesive of the desired shape is adhered to the customer for use. The general form is mesh + glue + bottom paper. Depending on the needs, we choose mesh yarns with different characteristics, such as waterproof, non-waterproof, and metallized.

There is also a common form: face paper + glue + mesh + bottom paper, this form of product has the dustproof function of the mesh, and also takes into account the double-sided adhesive paste function.

3, glue + foam: mainly plays a role in earthquake prevention. The foam and glue are brought together and die cut into the desired shape. The general form is: foam + glue + bottom paper; there is also a form: lining paper + foam + glue + bottom paper, this type of product has the function of shockproof, and has the function of double-sided adhesive.

According to the type of foam, it also plays a different role, but most of these products are used in the processing and assembly of electronic and digital products, advertising, electronic street signs, and LED board bonding.

4, glue + foam + glue + mesh category: the general form is: mesh + glue + foam + bottom paper. Mainly waterproof, dustproof, shockproof, or the electronic components and the case, etc., do not fall off, shift, etc.

The main role of this type of product is to protect the product from damage, and some require high aesthetics. However, some sophisticated electronic products require denser holes in the sand, and are smaller and have higher data requirements.

5, protective film: mainly used to paste on the surface of other products, such as: lenses, for protection. These products are currently required to be extremely strict, and no scratches or dirt are allowed.

Different protective film materials are generally selected depending on the application method and requirements. Commonly used materials are: Nitto7568, P1020, HR6030 and so on. Some products are used in the circulation process of other products to protect them. Generally, the next step or process will be torn off. Some protective films are directly listed on the terminal products, and their requirements are higher.

6, glue + non-woven fabric: also play the role of dust, waterproof. Commonly used materials are: 3M9448, etc., with good initial tack and holding viscosity, easy die-cutting processing, good stability, good adhesion to plastic, rubber, rough surface; good adhesion at high temperature, press tape The color is divided into white glue and black glue. Widely used in various fields such as automobiles, digital cameras, LCDs, TVs, PDAs, LCD monitors, and laptops.

7, other categories: such as conductive cloth, copper foil, aluminum foil, etc., mainly for shielding and conduction. This type of die-cut product is used between the heat source and the heat sink to eliminate the heat between the heat source and the heat sink, thereby making the heat dissipation of the electronic device more uniform and accelerating the heat dissipation efficiency of the material. Generally, various thermal interface materials need to have good thermal conductivity and surface wettability.
