What are the product structure classifications of die-cutting factories

Die cutting is a processing technique that uses a punch press to stop the indentation and punching of products in the mold. Traditionally, die-cutting is a general term for the in mold punching and creasing process of printing packaging materials. With the frequent rise and development of electronic products, die-cutting has evolved from the traditional packaging and printing material die-cutting to the mold stamping and cutting forming process for the contour hierarchy of soft and high-precision products such as stickers, foam, mesh, and conductive materials, collectively known as die-cutting.

Die cutting was once not limited to the development and specific positions of the electronics or printing industry. Today, any product that can be automatically cut, pressed, and formed using flat or circular rolling tools is considered a die cutting industry product. The scope it touched was not only limited to the electronic printing industry.

In consumption, we will encounter various die-cutting products, but common die-cutting products can be divided into the following categories according to their use and structure:

The common method is to use face paper, glue, and base paper. Under normal circumstances, there are single sheets of noodle paper with handles that differ in appearance from the adhesive; There are also single sheets without handles, with a shape larger than that of glue; The entire face paper is directly sandwiched with adhesive between the base paper, and both the face paper and the base paper have release properties. There are also PET materials available, and the release force is selected according to customer requirements.

The common method is mesh+tape+base paper. Choose different characteristics of mesh according to different needs, including waterproof, non waterproof, and metal plated, etc.

9759彩票集团Another common method is to use face paper, adhesive, mesh, and base paper. This method combines the dust-proof function of mesh with the adhesive function of double-sided tape.

9759彩票集团3. Glue+foam: mainly used for shock absorption. Combine foam and glue together and mold into the desired shape. The common method is: foam+glue+backing paper; There is another way: backing paper+foam+adhesive+backing paper. This type of product has both shock-absorbing function and double-sided adhesive function.

Depending on the type of foam, it can also have different effects, but these products are mostly used in electronic and digital product processing and assembly, advertising, electronic road signs, and LED board bonding and fixing.

4. Glue+foam+glue+mesh type: The common method is: mesh+glue+foam+base paper. Mainly used for waterproof, dustproof, and shockproof purposes, or to stick electronic components and casings together without falling or shifting.

The main function of this type of product is to decorate and maintain the product from damage. Some require high aesthetic appeal, but nowadays some sophisticated electronic products require denser and smaller holes in the mesh, resulting in higher data requirements.

5. Maintenance film: mainly used to stick on the surface of other products, such as lenses, for maintenance purposes. This type of product has strict external requirements and is not allowed to have scratches or dirt.

9759彩票集团Usually, different maintenance membrane materials are selected based on the application method and request. Commonly used materials include Nitto7568, P1020, HR6030, etc. Some products are applied to other products during the flow process for maintenance purposes. Usually, it will be torn off in the next stage or process, and some maintenance films are directly applied to the end product and put on the market, with higher requirements.

6. Adhesive+non-woven fabric: also has the functions of dust and water prevention. Commonly used materials include: 3M9448, which has good initial and holding adhesion, is easy to die cut, has good stability, and has good adhesion to plastics, rubber, and rough surfaces; It has good adhesion at high temperatures and is divided into white glue and black glue according to the color of the tape. Widely used in various fields such as automobiles, digital cameras, LCDs, TVs, PDAs, LCD displays, laptops, etc

7. Other types: such as conductive cloth, copper foil, aluminum foil, etc., mainly used for shielding and die-cutting of conductive shielding materials. This type of die-cutting product is used between the heat source and the heat sink. By sweeping the air between the heat source and the heat sink, the heat dissipation of electronic devices is more evenly distributed, which accelerates the heat dissipation efficiency. Ordinary thermal interface materials require good thermal conductivity and surface wettability
