The market for die-cutting and adhesives is very mature, with large demand and the same supply market. Die cutting and adhesive are different technologies, and the difficulty of adhesive is much higher than that of die cutting. Today we will explain the difference between die cutting and adhesive!

Die-cutting-use the mold to cut the specified material into the required 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 role in bonding, but also play a role in shock absorption and aesthetics. Various shapes and materials are cut according to customer requirements. Adhesives are used wherever bonding, electrical insulation, high temperature shielding, waterproof sealing, vibration absorbing buffer, electromagnetic shielding, corrosion protection and fire protection are required.

A) Double-sided tape die cutting:

Die cutting is to punch the required shape after pasting the backing paper of the existing products. Generally, brand double-sided tape and single-sided tape are used to apply, fix, conduct, and insulate between various parts, and prevent vibration, seal, and Dust, light, etc.

Brand double-sided tapes are: 3M (USA), TESA (Desha, Germany), NITTO (Japan's Nitto), SONY (Japan's Sony), DIC (Great Japan), SEKISUI (Japan Sekisui), TERAOKA (Japan Temple) , Taiwan Siwei and mainland China produced a variety of single and double tape.

B) Protective film die cutting:

The protective film can be divided into low viscosity, medium viscosity and high viscosity according to its adhesiveness. The viscosity can be selected according to the requirements of different industries.

In the manufacture, 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 harm the appearance of the product. Because it is a light adhesive type, it can be adhered and peeled under low tension.

3) Die-cutting of conductive shielding composite materials:

Common uses: conductive shielding, one side conductive, one side insulated, 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; insulation sheet

Common applications include

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

(2) The lower periphery of the PCB: shock absorption, shock absorption, gap filling, heat insulation effect.

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

(4) Around the battery: no pollution, absorption of impact sound, and improvement of air tightness.

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

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

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

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

(9) Around the cough: Prevent noise and fill gaps.

(10) Around the LCD: dustproof, shock-absorbing, fill gaps, improve light-shielding.

4) Die cutting of automotive foam gasket

3M VHB double-sided tape, foam tape, plasticizer-resistant double-stabilizing tape, tape that can reduce fogging, etc. are often used on automotive parts such as instrument panels, lamp housings, decorations, etc. The installation is more expressive and simple ,accurate. Noise and vibration reduction: Between metal and plastic parts; between plastic and plastic parts; between metal and metal parts, paste die-cut products made of foam, felt, anti-scratch textile To reduce noise and vibration.
