The die-cutting and adhesive market is very mature, and the demand is large. The same supply market is also very sufficient. Die cutting and gumming are different processes, and the difficulty of gumming is much higher than that of die cutting. Today we will explain in detail the difference between die cutting and adhesive!

Die cutting-use the die to cut the specified material into the desired shape to meet the needs of customers during assembly.

Adhesive-as a self-adhesive seal.

Adhesive can be used to bond electronic products with lenses and liquid crystal displays, such as mobile phones, PDA products, notebook computers and so on. It can not only play a good bonding role, but also can play the role of shock absorption and aesthetics. According to the requirements of customers, die-cut various shapes and materials. Adhesives are used wherever bonding, electrical insulation, high temperature shielding, waterproof sealing, vibration absorption buffering, electromagnetic shielding, anticorrosion and fire protection are required.

A) Double-sided tape die cutting: 

　　Die-cutting is to stamp the required shape after attaching the base paper to the existing products. Generally, brand double-sided tape and single-sided tape are used for pasting, fixing, conducting, insulating between various parts, anti-vibration, sealing, anti- Dust, avoid light, etc. 

Brand double-sided adhesive tapes are: 3M (USA), TESA (German tesa), NITTO (Japan Nitto), SONY (Sony Japan), DIC (Great Japan), SEKISUI (Japan Sekisui), TERAOKA (Japan Temple) , Taiwan Siwei and various single and double tapes produced in mainland China.

B) Die cutting of protective film: 

The protective film can be classified into low viscosity, medium viscosity, and high viscosity according to its adhesiveness. The viscosity can be selected according to the attributes required by different industries. 

　　In the manufacturing, processing, and transportation of optical films, protective films are widely used to protect these optical films. The material has extremely high transparency, so it will not damage the appearance of the product. Because it is a light adhesive type, it can be bonded and peeled under low tension.

C) Die-cutting of conductive shielding composite material: 

Common uses: Conductive shielding, one side conductive and one side insulation, double-sided insulation and middle conduction to prevent loosening, impact noise, and adhesion prevention. 

Material selection: imported and domestic conductive foam, conductive cloth tape, conductive copper and aluminum foil tape, conductive rubber, etc .; copper foil (Cu), aluminum foil (AL), Mylar thermal conductive silicon film; insulation sheet

Common application industries are

(1) Around the LED: prevent light leakage, absorb impact, and improve airtightness. 

(2) Lower perimeter of PCB: absorb shock, absorb vibration, fill gaps, heat insulation effect. 

(3) Keyboard gasket: rebound, no pollution, and good dimensional stability. 

(4) Around the battery: no pollution, absorb impact sound, improve air tightness. 

(5) Foot pads: good friction, no pollution, and good dimensional stability. 

(6) Rear pad of disk drive: absorb vibration, prevent impact noise, and improve air tightness. 

(7) Friction pads: good friction, no pollution, and good dimensional stability. 

(8) Disk cover cushion: absorb vibration, block motor noise, prevent vibration and improve air tightness. 

(9) Around the clamshell: prevent noise and fill gaps. 

(10) Around the LCD: Dustproof, absorb shock, fill gaps, improve shading.

4) Die cutting of automobile foam gasket 

3M VHB double-sided tape, foam tape, double-stabilized tape that can resist plasticizers, tape that can reduce fog, etc., often used on automotive parts such as instrument panels, lamp housings, decorative objects, etc. The installation is more express and simple ,accurate. Noise and vibration reduction: between metal parts and plastic parts; between plastic parts and plastic parts; between metal parts and metal parts, die-cut products made of foam, felt, scratch-resistant textiles, etc. are attached , To play the role of noise reduction and shock absorption.
