Automotive silicone waterproof plug, domestic automotive connector plug, waterproof sealing ring

Automotive rubber gaskets are a critical type of silicone product used for sealing and protection, widely applied in automotive, mechanical, and electrical fields. They primarily serve functions such as sealing holes, dustproof sealing, and fixed sealing. Their core purpose is to prevent the ingress of liquids, dust, and other contaminants into equipment, while also featuring high-temperature resistance, wear resistance, and corrosion resistance, ensuring stable operation of automotive and other equipment under complex working conditions.

Core Features of Silicone Waterproof Gaskets for Automotive Parts

Material Properties: Made of silicone material, it exhibits excellent resistance to high and low temperatures, maintaining elasticity within the range of -100°C to 300°C. Additionally, it is colorless, odorless, non-toxic, and environmentally friendly, meeting medical and food-grade safety standards. It also offers advantages such as ozone resistance and superior electrical insulation, enabling adaptation to various harsh environments.

Structural Design: The product specifications are diverse, with common types including solid plugs and hollow plugs. The outer diameter ranges from 2mm to ≥10mm, among others, allowing for the selection of appropriate dimensions based on specific usage scenarios. For some products, such as the waterproof plug model A0409 with dimensions D5.75H7.35Φ1.25, they meet standardized installation requirements.

Functional Advantages: In addition to its basic sealing function, it can also be used for part masking in processes such as powder coating, electroplating, and electrophoresis to prevent paint and chemical liquids from seeping in. It also features shock absorption, stability, and anti-slip properties. The silicone material is soft and easy to handle, supports reuse, and reduces long-term usage costs.

Silicone Waterproof Gasket Applications and Customization Services for Automotive Parts

Main Application Areas: Primarily used in automotive wiring harnesses, lamp heads, and connectors, while also expanding into industries such as electronics, electrical appliances, mechanical instruments, lighting, and sports equipment. For example, it is employed to seal and block holes in automotive lamp heads and to protect threaded holes, pipe ends, and other components from contamination during machining.

Custom Services: We support custom orders based on provided designs or samples, offering mold production tailored to client requirements. Utilizing liquid silicone injection molding technology, molds are typically made from S136 material, with a monthly production capacity of up to 10 sets. For custom products, precise calculations of formulations and molds are essential to ensure dimensional stability and reliable quality. Liquid silicone...
