The difference between die cutting and adhesive

Die-cutting molding and adhesive market has been very mature, the demand is large, the same supply market is also very sufficient. Die-cutting and back glue belong to different processes, and the difficulty of back glue is much higher than that of die-cutting. Today we will be the difference between die cutting and adhesive under the detailed explanation!

Die cutting-Use a mold to cut the specified material into the required shape to match the customer's needs during assembly.

Back glue-as a seal with self-adhesive force.

The adhesive may be used for bonding electronic products having a lens and a liquid crystal display, such as a mobile phone, a PDA product, a notebook computer, and the like. It can not only play a good bonding effect, but also can play a shock absorption and beautiful effect. According to customer requirements of punching and cutting various shapes and material selection. Where bonding, electrical insulation, high temperature shielding, waterproof sealing, vibration absorption buffer, electromagnetic shielding, anti-corrosion and fire prevention are required, adhesive will be used.

I) Die-cutting of double-sided adhesive tape:

Die cutting is the required shape of existing products after pasting back paper. Generally, brand double-sided adhesive tape and single-sided adhesive tape are used for pasting, fixing, conducting, insulating, anti-vibration, sealing, dustproof, avoiding light, etc.

Brand double-sided adhesive tapes are: 3M (United States), TESA (Germany Desa), NITTO (Japan Japan East), SONY (Japan Sony), DIC (Great Japan), SEKISUI (Japan Water), TERAOKA (Japan Temple), Taiwan Siwei and various single and double adhesive tapes made in mainland China.

II) Protective film die-cutting:

The protective film can be divided into low viscosity, medium viscosity and high viscosity according to its adhesion. Its viscosity can be selected according to different industry requirements.

In order to protect the optical films during the manufacture, processing, transportation, and the like of the optical films, a protective film is widely used. The material has an extremely high degree of transparency and therefore does not detract from the appearance characteristics of the product. Since it is a light adhesion type, adhesion and peeling can be performed under low tension.

3) Die-cutting of conductive shielding composite materials:

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

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

Common applications of the industry are

(1)LED around: to prevent light leakage, absorb impact, improve air tightness.

(2)PCB under the periphery: absorb shock, absorb shock, fill the gap, heat insulation effect.

(3) keyboard gasket: elastic, no pollution, good dimensional stability.

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

(5) foot pad: good friction, no pollution, good dimensional stability.

(6) Disk drive tail pad: absorb shock, prevent impact noise, improve air tightness.

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

(8) disc cover cushion: absorb vibration, cut off motor noise, shockproof, improve air tightness.

(9) around: to prevent noise, fill the gap.

(10) Around the LCD: dustproof, absorb impact, fill gaps, and improve shading.

4) Die-cutting of automotive foam gaskets

3M VHB double-sided adhesive tape, foam adhesive tape, anti-plasticizer double-stable adhesive tape, adhesive tape that can reduce fog, etc., are often used in automobile parts such as instrument panels, lamp housings, decorations, etc. The installation is more express, simple and accurate. Noise reduction and shock absorption: 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., To play the role of noise reduction and shock absorption.
