What are the extension products of precision rubber and plastic components in the field of electronics and electricity?

In the field of electronics and electricity, the extended products of precision rubber and plastic components are designed around five core functions: insulation protection, sealing and waterproofing, shock absorption and buffering, structural support and signal transmission assistance, and are suitable for consumer electronics, industrial control, communication base stations and photovoltaic energy storage. The specific product types and applications are as follows:

Insulation protection extension products

Connector insulation shell/terminal sheath: based on engineering plastics such as LCP, PA9T, PBT, etc., it has the characteristics of high temperature resistance, high frequency insulation and bending resistance after precision injection molding. It is used for 5G connectors and industrial aviation plugs to isolate current leakage and ensure stable signal transmission.

Motor/transformer insulating sleeve: made of silica gel and fluororubber, it is resistant to high and low temperature (-50℃~200℃) and arc. It is sleeved outside the motor winding and transformer lead to prevent short circuit, and is suitable for industrial servo motors and charging pile transformers.

Insulating gasket for PCB: Most of them are made of ultra-thin silica gel or polyimide composite rubber and plastic material, and the thickness can be as low as 0.1mm, which can accurately fit the gap between PCB board and shell to avoid short circuit caused by contact between metal shell and line.

Sealed waterproof extension products

Sealing ring of equipment cavity: With EPDM, silica gel and fluororubber as raw materials, it can be made into O-ring and special-shaped gasket by molding or extrusion, which is suitable for mobile phone, notebook computer and outdoor base station shell, realizing IP67/IP68 waterproof and dustproof, and resisting moisture and dust erosion.

Sealing strip for battery pack: It is made of TPE or silicone foam material, which is both elastic and sealing. It is used for battery modules and energy storage cabinets of new energy vehicles to prevent coolant leakage and external water vapor intrusion and ensure battery safety.

Sensor sealing assembly: customized special-shaped rubber and plastic parts, suitable for pressure sensors and temperature and humidity sensor probes, resistant to oil pollution and chemical corrosion, ensuring the measurement accuracy of sensors in harsh industrial environments.

Shock absorption and buffering extension products

Shock-absorbing foot pad for electronic devices: It is made of silica gel and polyurethane (PU) and designed into a round, square or special-shaped structure, which is attached to the bottom of servers, frequency converters and precision instruments to absorb the vibration caused by equipment operation, reduce noise and protect internal components.

Damping parts of rotating shaft: TPE or silicone composite materials are used for rotating shafts of notebook computers and security cameras. By accurately controlling the damping coefficient, the smooth hand feel of equipment can be realized when opening and closing, and the parts can be prevented from being damaged due to collision.

Harness damping buckle: Rubber-plastic material and nylon insert are integrally formed to fix the internal harness of automotive electronic and industrial equipment, buffer the harness pull caused by start-stop or vibration of the equipment, and prevent wires from breaking.

Extended products of structural support and functional assistance

Precision gears/transmission parts: Micro gears made of engineering plastics such as PEEK and POM by precision injection molding are used in the transmission systems of printers and smart home controllers, which have the advantages of self-lubrication, low noise and light weight, and can replace some metal gears to reduce costs.

Elastic components of key/switch: made of TPE and silica gel, made of film key shrapnel and touch switch dust cap, with soft touch and stable rebound, used in remote controllers and industrial control panels to improve the service life and operating feel of keys.

Damping frame of cooling fan: a fan fixing frame made of rubber and plastic material, which is suitable for cooling fans of servers and graphics cards, buffers the vibration of the fan running at high speed, and at the same time isolates the fan noise from being transmitted to the equipment shell.
