Rogers foam application and processing technology detailed introduction

Rogers foam is a kind of excellent performance foam, suitable for cars, electronic devices, refrigerators, central air conditioning, in addition to open dispensing, production and processing, and its related products customized, punching, heat resistance to 150℃, ultra-low temperature to minus 40℃. In the die-cutting production and processing of electronic device auxiliary materials, it also has irreplaceable effects. Today I'm going to join you to learn all about Rogers foam.

First, Rogers foam characteristics:

1, specifications and models: 0.79mm, 1.57mm, 1.14mm, 2.36mm, 6.35mm, 12.7mm, 4.78mm, 9.53mm, 0.53mm, length and total width can be manufactured in accordance with the actual provisions.

2, tone: gray black, dark gray.

3, adhesion: high adhesion, high external force, temperature resistance and acid resistance. The application of super glue thickness is not the same. The second layer uses silicone vulcanized rubber; For converters, small computer keyboards, electronic components.

4, wear resistance, high temperature resistance, low temperature resistance, buffer, sound insulation, seismic, sealed; Such as excellent shrinkage resistance, extremely high resilience, impact resistance, elastic continuity, etc., are widely used in a variety of fine goods earthquake resistance and other effects.

2. Scope of application:

① Control panel layer: zero pollution, avoid loose, avoid collision noise, avoid adhesion.

②LED periphery: avoid light transmission, impact absorption, single high sealing.

③ Near the PCB: absorbing impact, absorbing vibration, making up the gap, heat insulation and insulation actual effect.

④ Keyboard gasket: anti-ductility, zero pollution, good reliability specifications.

⑤ Rechargeable battery surrounding: zero pollution, absorption of impact sound, improve sealing.

⑥ Cushion: good coefficient of friction, zero pollution, good reliability specifications.

⑦ Disc end sanitary napkins: absorb vibration, avoid collision noise, improve sealing.

⑧ Friction washer: good coefficient of friction, zero pollution, good specification reliability.

⑨ disc cover sponge pad: absorb vibration, block motor noise, seismic, improve sealing.

⑩ Speakers around: avoid noise, make up the gap.

Around the LCD: anti-fouling, impact absorption, gap making up, improve light blocking.

● Application in the car industry:

1, high brake light: waterproof and block light;

2, LED and operating panel gasket: gasket;

3, rear view camera and shining signal light: waterproof and antifouling, sealing pad;

4. Reverse camera: waterproof and antifouling seal;

5, shift door: cache;

6, lithium battery pack: natural environment seal/spacing.

● Application on power lithium battery:

Advantages:

1, a variety of thin and thick selection;

2, excellent heat transfer;

3, excellent reduction characteristics and resilience;

4, flame retardant to UL94-V0;

5, in line with Rohs standards.

● Application of bullet trains on high-speed rail:

Exhaust system software seal, display seal ring, lighting cabinet seal ring, HVAC engineering seal, sound insulation and noise reduction, overhead seal, door seal, wind and according to table seal, gap filling, chair foam, aluminum silicate fiber, electrical control cabinet seal ring, fluctuating wood floor material.

Third, Rogers foam die-cutting:

1, machine equipment: rotating die cutting machine

Production and processing method: roll cutting

CNC blade: Metal material hand carved round blade

Application: complex processing technology, a lot of production of goods die cutting

2. Detailed introduction of materials:

Self-adhesive, protective film, sponge, wire mesh, metal foil, composite, double-sided tape;

3. Detailed introduction of processing technology:

Segmentation - subvolume - compound - die cutting

segmentation

Raw material dealers generally have very few standard size rolls of material. This specification of materials generally can not be applied, the length and total width are not consistent with the provisions of production and processing, at this time, we can change the length and total width of the material roll according to the rewinding/segmentation, to consider the provisions of production and manufacturing. We can divide all kinds of materials. For example: plastic film, paper, cloth, pharmaceutical tape and industrial production tape.

Rewinding/slitting

Method - Longitudinal section

Machine equipment - rewinding slitter machine, rotating die cutting machine equipment

Numerical control blade - head, slot cutting head, air cutting head

Application - PET film, paper, composite material and so on

Die-cutting process analysis (Figure) :

Sub-roll:

Method: Cross section

Machine equipment: automatic cutting table

CNC blade: beef rib kitchen knife, white steel single and double blade knife, round wheel knife

Application: Cut tape, foam, protective film, etc

Compound type:

Using pressure sensitive tape as a medium, two or two kinds of materials above are bonded together, and the composite material has the characteristics of a variety of materials, so that the non-pressure sensitive material has more and more pressure sensitive and self-adhesive characteristics. This type of processing can produce non-standard materials to incorporate requirements that cannot be considered with a single material.

Method: pressing

Machine equipment: crosscutting machine, rotating die cutting machine equipment

Application: rubber foam, rubber sheet, rubber and so on

Die cutting production before manufacturing compound or compound die cutting in addition to production and processing.
