Die & double side tape ----------- Chris Gu China Coverting

Die

Type of the die： wooden die, etching die, plastic board die, metal die, caving die, QDC die etc.

Normal height of the die: Red back ground is the most popular height customers using.

Etching die：2、2.5、3mm (According to the thickness of the fixed board, the back board can be 6mm or 20mm etc.)

Caving die：8、23mm   (According to the processing requirement, choose the right height.）

Plastic board die：7、8、10、12mm    

Wooden die：23.6、23.8mm   

Aluminum board die：8mm

Die for sucking hole wastage：23-25mm (Etching die, caving die can be used for suck hole wastage.)

Metal die：90、115、120mm（According to the die cutting machine, choose relative height.）

QDC die：90、115、120mm（According to the die cutting machine, choose relative height.）

Sharp of the die blade：

Etching die：

After immersed in the liquid medicine, get the outline of the mold. The rough-cut knife mold is placed in the CNC engraving machine for manufacturing.

The processing time depends on the length of the knife line. It is generally 1 to 4 hours.

The etched knife mold has a very high dimensional accuracy, which can generally be maintained at ± 0.03mm, the flatness of the blade is good, the sharpness is normal, and the lifetime isn’t long.

Caving die：

The material of the carving die: hardness is more than 50 degrees, thickness is 8mm steel.

Characteristic: more durable, long lifetime. Can be re-sharping several times.

High precision, about ± 0.03mm, not easy deforming, flatness of the blade is good.

Plastic board die：

According to the product shape, use CNC machine to cut the slot on the board.

The cutting blade is manually / automatically folded into the corresponding shape by the bending machine, and it can be inserted into the slot of the board.

Generally suitable for die cut label paper products. It has good flatness. Low cost, the thin blade isn’t suitable for punching hard materials.

Wooden die:

According to the product pattern, cut the wood board by CNC machine.

Manual or auto bend the blade by the bending machine.

Insert the blade into the board.

The accuracy is general and the scope of application is wide, such as PET / PC, insulating materials, Copper and aluminum foil, and other general die cutting materials, there are many different type blades, boards for choosing. long life, low production cost and other advantages, compared with the plastic board die, the flatness is slightly worse.

Aluminum board die:

CNC machine cut the slot on the aluminum board. And bend the blade, insert the blade into the slot.

Good flatness, lower cost, the blade can be changeable, not affect the accuracy etc. Not suitable for die cut thick material.

Die for such hole wastage：

The waste suction die is mainly used for suck wastage of the small holes. The diameter is about 1-10mm. Automatically remove the wastage avoid manual digging.

Aluminum board with die to about 23mm thickness, cut slot at the relative position, for wastage move out. Compare with normal etching die or caving die, the lifetime is little weak.

Metal die：

It is suitable for punching hard plastics, cardboard, and insulating paper. It was first used for the punching of steel sheets in the hardware industry. It can be installed on a die cutting machine for continuous punching.

Wastage of the small hole can be automatically separate from the product.

QDC die：

QDC is the English abbreviation for quick die change.

Install the caving die or etching die into the metal die for cutting and punching holes. You can quickly replace the caving die or etching die and quickly, replace the positioning hole according to different die cutting needs. Making it a common die, with the advantage of normal die and metal die.

Die cut material

Double side tape

Type of double side tape：PET、Nonwoven fabric, woven fabric, glass fiber, no base material etc.

Base material：PET、Non-woven fabric, woven fabric, foam etc.

Structure of the tape:

PET double side tape：

Common thickness: 0.05-0.2MM, with good dimensional stability, thermal stability, chemical stability, good initial adhesion and holding viscosity, easy die cutting processing, good adhesion to plastic, rubber, nameplate; applicable Wider temperature range and harsh environment; long-term temperature resistance 100-120 ℃, short-term temperature resistance up to 140-200 ℃

Non-woven fabric double side tape：

The common thickness: 0.15-0.16mm; the color is divided into white translucent and black; easy to operate, durable, good temperature resistance, waterproof, good resilience, strong adhesion; short-term temperature resistance 120- 150 ℃, long-term temperature resistance 70-80 ℃

No substrate double-sided tape：

Common thickness: 0.06-0.13MM, the color of the tape is transparent, has excellent adhesion effect, can prevent shedding and excellent waterproof performance, good processability, good temperature resistance, dimensional stability, thermal stability, chemical stability Good performance, good initial stickiness and good stickiness; can be applied to a wider temperature range and harsh environment; long-term temperature resistance 80-95 ℃, short-term temperature resistance up to 180-205 ℃;

Conductive double-sided tape：

It is a kind of adhesive with certain conductive properties after curing or drying. The conductive particles are combined together through the adhesion of the matrix resin to form a conductive path to realize the conductive connection of the adhered material.

Thermally conductive double-sided adhesive: Double-sided thermally conductive adhesive is a kind of high-performance acrylic pressure-sensitive adhesive filled with high thermal conductivity ceramic particles coated on both sides of glass fiber cloth or no substrate, and is used in high-power LED lighting aluminum substrate and radiator Adhesive installation, CPU heat sink, LED backlight module TV, etc.

Foam material

Foam is divided into PU foam, antistatic foam, conductive foam, EPE, EPP, flame retardant foam, antistatic EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, XPE foam and IXPE foam, etc.

EVA foam：

There are two types of foaming styles: 1. Closed-cell foaming (EVA pads are usually closed-cell foaming), 2. Open-cell foaming.

Color: white, black, colorful, more white and black are commonly used in industry, and colorful is less.

EVA hardness: 25, 38, 45, 50, 60, 70, 80 degrees, the industry commonly used foot pads are 38 or 45 degrees, electronic internal accessories are generally 25-38 degrees.

Characteristics:

The closed cell structure is non-absorbent, moisture-proof, and has good water resistance. It is easy to be processed by hot pressing, cutting, gluing, and laminating. It has high resilience and tensile strength, high toughness, and has good shock resistance, anti-skid, and buffer properties.

CR foam:

Lightweight and has strong toughness, low thermal conductivity, excellent thermal insulation, independent bubble structure, low water absorption, excellent impact resistance, can be used as a buffer material.

Usage

Cushioning materials for transportation of precision machinery, medical equipment, furniture, glass, etc., protective cushioning materials for small electrical appliances, door sealing materials, luggage compartment sealing materials, engine hood cushioning gaskets, various pipe sealing materials, lighting seal materials, engines Shockproof materials, instrument buffers and sealing materials, cooler and air conditioner use insulation sealing materials, refrigerator and freezer insulation sealing materials, noise prevention sealing materials for various mechanical equipment, residential soundproofing wall sealing materials, waterproofing of various electrical appliances Moisture-proof sealing materials, moisture-proof sealing materials for various mechanical equipment, etc.

With foaming, cutting, special-shaped cutting, hot press forming, punching, grinding and compounding processing methods and processing equipment, it can process various products of different specifications.

EPDM foam：

EPDM foam Sponge Product Features: The product is divided into closed-cell and open-cell foam.

The closed-cell foam material has a wall membrane between the cells and the cells, which are not connected to each other. It has an independent cell structure and mainly It is a small cell shape or extremely fine micropores. The internal cells of the open-cell foam material communicate with each other and communicate with the outer skin. It is a non-independent cell structure, mainly large cells. Or coarse holes.

Foaming has excellent weather resistance, ozone resistance, corrosion resistance, heat stability, good thermal insulation, thermal insulation, shock absorption, sound absorption, sound insulation, sealing and flame retardant. Ethylene-propylene rubber products can be used at -40 ~ 120 ℃.
