Molded sheet metal

Conductive silicone rubber molded sheets have good conductivity by adding conductive particles (such as silver plated glass microspheres, aluminum silver plated particles, etc.) to the silicone rubber matrix. This conductivity enables the material to perform well in electromagnetic shielding, effectively shielding electromagnetic interference (EMI).

CHARACTERISTICS

1. Conductivity: The uniformly distributed conductive particles inside the molded conductive silicone rubber sheet give it good conductivity, which can provide a stable conductive path under certain pressure and effectively suppress electromagnetic interference.

2. Sealing performance: The silicone rubber substrate has good sealing performance, which can effectively prevent moisture, dust, and other harmful substances from entering and protect internal electronic devices from damage.

3. Mechanical properties: The molding process endows the sheet with high mechanical strength, making it less prone to deformation or fracture during use and able to withstand certain tensile and compressive forces.

4. Weather resistance: Conductive silicone rubber sheets usually have excellent heat resistance, cold resistance, oil resistance, and chemical corrosion resistance, and can maintain stable working conditions in various harsh environments.

5. Customizability: Different sizes, thicknesses, and conductivity of sheets can be customized according to the specific needs of users to meet the requirements of various application scenarios.

2、 Application Fields

Molded conductive silicone rubber sheets are widely used in multiple fields due to their unique properties:

1. EMC field: As a shielding material, it is used for electromagnetic shielding and sealing of small and medium-sized military electronic chassis, cabinets, shelters, and microwave waveguide systems.

2. Aerospace: In the manufacturing of spacecraft and aircraft, it is used to make components that require high conductivity and sealing performance, such as connector gaskets, sealing gaskets, etc.

3. Electrical and Electronic: Used in electrical equipment, electronic products, and communication devices to make conductive connectors, grounding pads, seals, etc., ensuring the normal operation and safety of the equipment.

4. Medical devices: In the manufacturing of medical devices, conductive silicone rubber sheets can be used to make conductive electrodes and other components, improving the accuracy and durability of medical devices.

3、 Production process

The production process of molded conductive silicone rubber sheet mainly includes the following steps:

1. Raw material preparation: Select high-quality silicone rubber as the base material and prepare an appropriate amount of conductive particles.

2. Mixing and dispersion: Evenly disperse conductive particles in silicone rubber to ensure uniform distribution of conductive particles in the rubber.

3. Compression molding: Place the mixed conductive silicone rubber into a mold, apply certain pressure and temperature for compression molding, and obtain the desired shape of the sheet.

4. Sulfurization treatment: Sulfurization treatment is applied to the molded sheet to cure it and achieve stable physical and chemical properties.

5. Quality inspection and packaging: Conduct quality inspection on the vulcanized board to ensure that its conductivity, sealing performance, and durability meet the requirements, and then package it for storage and transportation.
