In electronic products, various components such as screen, receiver, microphone, keyboard and so on, the functions of fixing, sealing, dust-proof, shock-proof and protection between them need to be accomplished by a large number of adhesive products.

In the field of rotating die-cutting of such adhesives, more than one die-cutting workstation and more than one feeding roll and feeding roll on rotating die-cutting equipment, and one or more feeding belts are discharged by feeding roll.
The tapes of different materials are processed into different shapes and sizes. Each workstation completes die-cutting of one shape for the tape. The different shapes of the rubber parts cut by different positions of rotary die-cutting equipment are precisely combined according to certain position relations, and finally the adhesive products are formed.
Classification of Adhesive Products
1. According to the application method, it can be divided into thermosetting type, hot melting type, room temperature curing type, pressure sensitive type, etc.

2. According to the application object, it can be divided into structural type, non-structural type or special adhesive. The structural adhesives include epoxy resin, polyurethane, organosilicon, polyimide and other thermosetting adhesives; polyacrylate, polymethacrylate, methanol and other thermoplastic adhesives; special adhesives such as high temperature resistance, ultra-low temperature, conductivity, thermal conductivity, magnetic conductivity, sealing, water adhesives, etc.  Modified multi-component adhesives, such as Phenolic-Epoxy type, etc.

3, according to the form of curing, it can be divided into four types: solvent volatilization, emulsion type, reaction and hot melt type.

4. Synthetic chemists often like to classify adhesives according to their chemical composition.

5. It can be divided into organic and inorganic categories according to the main components.

6. According to appearance, it can be divided into three categories: liquid, paste and solid.

7. Classified by components: single component, two components, reactive type.
